3 General Principles
FLUXUS F60x
3
General Principles
For the ultrasonic measurement of the flow rate, the flow velocity of the fluid in a pipe is
determined. Further physical quantities (e.g., volumetric flow rate, mass flow rate, heat
flow rate) are derived from the flow velocity and from additional physical quantities, if
necessary.
3.1
Measurement System
The measurement system consists of a transmitter, the ultrasonic transducers with the
transducer cables and the pipe on which the measurement is conducted.
The ultrasonic transducers are mounted on the outside of the pipe. Ultrasonic signals are
sent through the fluid and received by the transducers. The transmitter controls the mea-
suring cycle, eliminates the disturbance signals and analyzes the useful signals. The
measured values can be displayed, used for calculations and transmitted.

Fig. 3.1: Example of a measurement setup
3.2
Measurement Principle
The flow velocity of the fluid is measured in the TransitTime mode using the ultrasonic-
transit time difference correlation principle (see section 3.2.2). If the proportion of gas or
solid particles is high, the transmitter can toggle to the NoiseTrek mode (see section
3.2.3).
3.2.1
Terms
Flow profile
Distribution of the flow velocities over the cross-sectional pipe area. For an optimal mea-
surement, the flow profile has to be fully developed and axisymmetrical. The shape of the
flow profile depends on whether the flow is laminar or turbulent and is influenced by the
conditions in the supply line of the measuring point (see chapter 5).

FLUXUS F60x
3 General Principles
Reynolds number Re
Coefficient describing the turbulence behavior of a fluid in the pipe. The Reynolds num-
ber Re is calculated from the flow velocity, the kinematic viscosity of the fluid and the in-
ner pipe diameter.
If the Reynolds number exceeds a critical value (usually approx. 2 300, if the fluid flows in
a pipe), a transition from a laminar flow to a turbulent flow takes place.
Laminar flow
A flow without any turbulence. There is no disruption between the parallel flowing layers
of the fluid.
Turbulent flow
A flow in which turbulence (swirling of the fluid) occurs. In technical applications, the flow
in the pipe is mostly turbulent.
Transition range
The flow is partly laminar and partly turbulent.
Transit time difference ∆t
Difference of the transit times of the signals. In the TransitTime method, the transit time
difference of the signals in and against the flow direction is measured, in the NoiseTrek
mode – the time difference of the signal from the transducer to the particle and from the
particle to the transducer. The flow velocity of the fluid flowing in the pipe is determined
from the transit time difference (see Fig. 3.2, Fig. 3.3, Fig. 3.4 and Fig. 3.5).
Sound speed c
Speed of the propagating sound. The sound speed depends on the mechanical proper-
ties of the fluid or the pipe material. In pipe materials and other solid materials, a distinc-
tion is made between the longitudinal and transversal sound speed. For the sound speed
of some fluids and materials see annex C.
Flow velocity v
Average value of all flow velocities of the fluid over the cross-sectional pipe area.
Acoustic calibration factor ka
c
ka =
————
sin
The acoustic calibration factor ka is a parameter of the transducer which results from the
sound speed c within the transducer and the angle of incidence (see Fig. 3.2). According
to Snell’s law of refraction, the angle of propagation in the adjoining fluid or pipe material
is:

Fluid mechanics correction factor kRe
With the fluid mechanics correction factor kRe, the measured value of the flow velocity in
the area of the sound beam is converted into the value of the flow velocity across the
whole cross-sectional pipe area. In case of a fully developed flow profile, the fluid me-
chanics correction factor only depends on the Reynolds number and the roughness of
the inner pipe wall. The fluid mechanics correction factor is recalculated by the transmit-
ter for each new measurement.
Volumetric flow rate
V·
V· = v · A
The volume of the fluid that passes through the pipe per unit time. The volumetric flow
rate is calculated from the product of the flow velocity v and the cross-sectional pipe area
A.
Mass flow rate
m·
m·
=
V·
· ρ
The mass of the fluid that passes through the pipe per unit time. The mass flow rate is
·
calculated from the product of the volumetric flow rate V and the density ρ.
Heat flow Φ
The heat quantity that is transferred per unit time. For the calculation of the heat flow see
chapter 20.
3.2.2
Measurement of the Flow Velocity in the TransitTime Mode
The signals are emitted and received by a transducer pair alternatively in and against the
flow direction. If the fluid moves, the signals propagating in the fluid are displaced with
the flow. This displacement causes a reduction in distance for the signal in the flow direc-
tion and an increase in distance for the signal against the flow direction in the section of
the receiving transducer (see Fig. 3.2 and Fig. 3.3). This causes a change in the transit
times. The transit time of the signal in the flow direction is shorter than the transit time
against the flow direction. This transit time difference is proportional to the average flow
velocity.
The average flow velocity of the fluid is calculated as follows:
t
v = kRe · ka ·

3.2.3
Measurementof the Flow Velocity in the NoiseTrek Mode
When fluids with a high proportion of gas bubbles or solid particles are measured, the at-
tenuation of the ultrasonic signal increases and can inhibit the propagation of the signal
in the fluid. A measurement in the TransitTime mode is not possible anymore.
The NoiseTrek mode uses the presence of gas bubbles and solid particles in the fluid.
The measurement setup used in the TransitTime mode does not need to be changed. Ul-
trasonic signals are sent into the fluid at short intervals, reflected by the gas bubbles or
the solids particles and again received by the transducer. The transit time difference be-
tween two consecutive measuring signals that are reflected by the same particle is deter-
mined. The transit time difference is proportional to the distance covered by the particle
in the time between the two measuring signals and therefore to the velocity at which the
particle moves through the pipe (see Fig. 3.5).
The average value of all measured velocities of gas bubbles and/or particles corre-
sponds to the flow velocity of the fluid:

Depending on the signal attenuation, the error of measurement in the NoiseTrek mode
can be greater than in the TransitTime mode.

HybridTrek Mode
The HybridTrek mode combines the TransitTime mode and the NoiseTrek mode. During
a measurement in the HybridTrek mode, the transmitter automatically toggles between
the TransitTime mode and the NoiseTrek mode depending on the gaseous or solid con-
tent.

Measurement Arrangements
3.3.1
Terms
Diagonal arrangement
The transducers are mounted on the opposite sides of the pipe (see Fig. 3.6).
Reflection arrangement
The transducers are mounted on the same side of the pipe (see Fig. 3.7).
Fig. 3.6: Diagonal arrangement
Fig. 3.7: Reflection arrangement
Sound path
The distance covered by the ultrasonic signal after crossing the pipe once. The number
of the sound paths is:
• odd if the measurement is conducted in the diagonal arrangement
• even if the measurement is conducted in the reflection arrangement
(see Fig. 3.9 or Fig. 3.8).
Beam
The path covered by the ultrasonic signal between the transducers: the transducer emit-
ting the ultrasonic signal and the transducer receiving it. A beam consists of 1 or several
sound paths (see Fig. 3.8or Fig. 3.9).

Selection of the Measuring Point
Attention!
Observe the Safety Instructions for the Use in Explosive Atmo-
sphere (see document SIFLUXUS_608).
The correct selection of the measuring point is crucial for achieving reliable measure-
ment results and a high measurement accuracy.
A measurement on a pipe is possible if
• the ultrasound propagates with a sufficiently high amplitude (see section 5.1)
• the flow profile is fully developed (see section 5.2)
The correct selection of the measuring point and thus, the correct transducer positioning
guarantees that the sound signal will be received under optimum conditions and evaluat-
ed correctly.
Due to the variety of applications and the different factors that influence the measure-
ment, there is no standard solution for the transducer positioning. The correct position of
the transducers is influenced by the following factors:
• diameter, material, lining, wall thickness and shape of the pipe
• fluid
• gas bubbles in the fluid
Avoid measuring points in the vicinity of deformations and defects of the pipe and in the
vicinity of welds.
Avoid locations with deposit formation in the pipe.
The ambient temperature at the measuring point has to be within the operating tempera-
ture range of the transducers (see Technical Specification (FLUXUS F601) or (FLUXUS
F608)).
Select the location of the transmitter within the range of the cable of the measuring point.
The ambient temperature at the measuring point has to be within the operating tempera-
ture range of the transmitter (see Technical Specification (FLUXUS F601) or (FLUXUS
F608)).).
If the measuring point is within an explosive atmosphere, the danger zone and gases that
may be present have to be determined. The transducers and the transmitter have to be
appropriate for these conditions.
5.1
Acoustic Penetration
The pipe has to be acoustically penetratable at the measuring point. The acoustic pene-
tration is reached when pipe and fluid do not attenuate the sound signal so strongly that it
is completely absorbed before reaching the second transducer.
The attenuation in the pipe and in the fluid depends on:
• kinematic viscosity of the fluid
• proportion of gas bubbles and solids in the fluid
• deposits on the inner pipe wall
• pipe material
24
UMFLUXUS_F6V4-5-1EN, 2016-05-11
5 Selection of the Measuring Point
FLUXUS F60x
The following requirements have to be met at the measuring point:
• the pipe is always filled completely
• no material deposits in the pipe
• no bubbles accumulate
Note!
Even bubble-free fluids can form gas pockets when the fluid ex-
pands, e.g., before pumps and after great cross-section extensions.
Observe the notes in the following table:
Tab. 5.1: Recommended transducer mounting position
horizontal pipe
Select a measuring point where the transducers can be mounted on the side of the
pipe, allowing the sound waves to propagate in the pipe horizontally . . By doing this,
the solid on the bottom of the pipe or gas bubbles in the pipe’s upper part are prevent-
ed from influencing the propagation of the signal.

Undisturbed Flow Profile
Some flow elements (elbows, slide valves, valves, control valves, pumps, reducers, dif-
fusers, etc.) distort the flow profile in their vicinity. The axisymmetrical flow profile needed
for correct measurement is no longer given. A careful selection of the measuring point
helps to reduce the impact of disturbance sources.
It is most important that the measuring point is chosen at a sufficient distance from any
disturbance sources. Only then it can be assumed that the flow profile in the pipe is fully
developed. However, measuring results can be obtained even if the recommended dis-
tance to disturbance sources cannot be observed for practical reasons.
Recommended straight inlet and outlet pipe lengths for different types of flow disturbance
sources are shown in the examples in Tab. 5.2.

8.1
Preparation of the Pipe
• The pipe has to be stable. It has to be able to withstand the pressure exerted by the
transducer mounting fixture.
Rust, paint or other deposits on the pipe absorb the sound signal. A good acoustic con-
tact between the pipe and the trans-ducers is obtained as follows:
• Clean the pipe at the selected measuring point:
– If present, the paint layer has to be smoothed by sanding. The paint does not need to
be removed completely.
– Remove any rust or loose paint.
• Use coupling foil or apply a bead of acoustic coupling compound along the center line
of the contact surface of the transducers.
• Observe that there must be no air pockets between the transducer contact surface and
the pipe wall.
8.2
Orientation
Mount the transducers onto the pipe in such way that the engravings on the transducers
form an arrow (see Fig. 8.1). The transducer cables show in opposite directions.
For the determination of the flow direction see section 11.8.

Installation of the Transducers with Portable Variofix Rail
with Chains
Normally, each transducer is mounted to its own Variofix rail. If the transducer distance is
small and both transducers are on the same side of the pipe (reflection arrangement),
they can be fixed in one Variofix rail.
Preparation and installation of the Variofix rail
• Adjustment of the Variofix rail to transducer width:
– Loosen the 4 screws (1) for the adjustment of the rails (2) with a M8 wrench (see Fig.
8.5).
– Place one transducer (3) in the center between the rails.
– Press the two rails (2) together and tighten the 4 screws (1). The transducer can be
shifted and removed.
– Remove the transducer.
• Loosen the chain tensioners (4), but do not unscrew them completely.
• If the chain has not yet been mounted in the rail support (6):
Compress the spring of the chain tensioner (4) with the cylinder (7) while pushing the
chain tensioner (4) in the horizontal groove (5) of the rail support (6).
• Place the Variofix rail on the pipe. Both rail supports (6) have to be completely support-
ed by the pipe. Lay the ball chain (8) around the pipe (if the pipe is vertical, start with the
upper ball chain).
• Press the chain tensioner (4) inside completely and push the ball chain (8) into the oth-
er groove (9) of the rail support.
• Fix the second ball chain (8) in the same way.
• Tension the ball chains (8) by tightening the chain tensioners (4).
• Repeat the steps if the second transducer is fixed to its own Variofix rail.
Installation of the transducer
• Force apart the legs of the spring clip (10) and clamp it over the outer side of the rails
(2). The height where the spring clip will snap in depends on the height of the transduc-
er.
• Apply some coupling compound to the contact surface of the transducer.
• Place the transducer between the rails (2). Observe the mounting direction (see Fig.
8.5).
• Push the spring clip (10) over the transducer until the knurled screw (11) is positioned
over the blind hole of the transducer.
• Fix the transducer by tightening the knurled screw by hand (11).
• Repeat the steps for fixing the second transducer.
• Adjust the transducer distance by loosening the knurled screw (11) of a spring clip (10)
and shifting the transducer.

11.6.2
Consistency Check
If a wide range for the sound speed has been entered in the program branch parameter
or the exact parameters of the fluid are unknown, a consistency check is recommended.
The transducer distance can be displayed during the measurement by scrolling the key
The optimum transducer distance is displayed in brackets
L=(50.0) 54.0 mm
(here: 50.0 mm) in the upper line, followed by the entered
54.5
m3/h
transducer distance (here: 54.0 mm). The latter value has
to correspond to the adjusted transducer distance.
The optimum transducer distance is calculated on the basis of the measured sound
speed. It is therefore a better approximation than the first recommended value which had
been calculated on the basis of the sound speed range entered in the program branch
parameter.
If the difference between the optimum and the entered transducer distance is less than
specified in Tab. 11.1, the measurement is consistent and the measured values are valid.
The measurement can be continued.
If the difference is greater, adjust the transducer distance to the displayed optimum val-
ue. Afterwards, check the signal quality and the signal amplitude bar graph (see section

Also write down the fluid temperature because the sound speed depends on the tem-
perature. The value can be entered in the program branch parameter or a user defined
fluid can be created for this sound speed (see section 16.2 and 16.3).

ducer distance (see section 11.6.1).
If more than one measuring channel is available/activated, the transmitter works with an
integrated measuring point multiplexer providing simultaneous measurement on the dif-
ferent measuring channels.
The flow rate is measured on one measuring channel for approx. 1 s, then the multiplexer
switches to the next activated channel.
The time necessary for the measurement depends on the measruing conditions. E.g., if
the measuring signal cannot be detected immediately, the measurement duration might
be > 1 s.
The outputs and the serial interface continuously receive the measured values of the cor-
responding channel. The results are displayed according to the currently selected output
options. The default unit of measurement of the volumetric flow rate is m3/h. For the se-
lection of the values to be displayed and for the setting of the output options see chapter
12. For further measuring functions see chapter 13.

Detection of the Flow Direction
The flow direction in the pipe can be detected with the help of the displayed volumetric
flow rate in conjunction with the arrow on the transducers:
• The fluid flows in the direction of the arrow if the displayed volumentric flow rate is posi-
tive (e.g., 54.5 m3/h).
• The fluid flows against the arrow direction if the displayed volumetric flow rate is nega-
tive (e.g., -54.5 m3/h).

Calculation Channels
In addition to the ultrasonic measuring channels, the transmitter has two virtual calcula-
tion channels Y and Z. The measured values of the measuring channels A and B can be
calculated by means of the calculation channels.
The result of the calculation is the measured value of the selected calculation channel.
This measured value is equivalent to the measured values of a measuring channel. All
operations with the measured values of a measuring channel (totalizing, online transmis-
sion of data, storing, outputs, etc.) can also be done with the values of a calculation
channel.
13.8.1
Characteristics of the Calculation Channels
In the program branch Parameter, the measuring channels to be used for the calcula-
tion and the calculation function have to be entered.
A calculation channel cannot be attenuated. The damping factor has to be set separately
for each of the two measuring channels.
Two cut-off flow values for each calculation channel can be defined. The cut-off flow is
not based on the flow velocity as for measuring channels. Instead, it is defined in the unit
of measurement of the physical quantity selected for the calculation channel. During the
measurement, the calculated values are compared to the cut-off flow values and set to
zero if necessary.
A calculation channel provides valid measured values if at least one measuring channel
provides valid measured values.

Data Logger and Transmission of Data
The transmitter has a data logger in which the measured values are stored during the
measurement (see section 14.1).
The measured values are transmitted to a PC via the serial interface directly during the
measurement (see section 14.2).
For the connection of the serial interface to the transmitter see section 6.7 (FLUXUS
F601) or section 7.7 (FLUXUS F608).
14.1
Data Logger
The following data will be stored:
• date
• time
• measuring point number
• pipe parameters
• fluid parameters
• transducer data
• sound path (reflection or diagonal arrangement)
• transducer distance
• damping factor
• storage rate
• physical quantity
• unit of measurement
• measured values (physical quantity and input quantities)
• values of the totalizers (if totalizers is activated)
• diagnostic values (if storing of diagnostic values is activated)
In order to store the measured data, the data logger has to be activated (see section
14.1.1).
The available data logger memory can be displayed (see section 14.1.6).
The storing of each measured value will be signalized acoustically. This signal can be
de-activated (see section 14.1.3 in Acoustic Signal).

Setting the Storage Rate
The storage rate is the frequency at which the measured values are transmitted or
stored. The storage rate is set separately for each measuring channel.
If the storage rate is not set, the storage rate which was selected previously will be used.
The storage interval should be at least equal to the number of activated measuring chan–
nels, e.g., the storage interval of a channel should be min. 2 s if 2 measuring channels
are activated, min. 4 s are recommended.

Setting the ringbuffer influences the storing of measured values once the data logger is
full.
• If the ringbuffer is activated, the available data logger will be halved. The oldest mea-
sured values will be overwritten. Only the data logger memory that was free during the
activation will be used by the ringbuffer. If more data logger memory is necessary, mea-
sured values in the data logger should previously be deleted.

Libraries
The internal material database of the transmitter contains parameters for pipe and lining
materials as well as for fluids. It can be extended with user defined materials or fluids.
User defined materials and fluids will always be displayed in the scroll lists of the pro-
gram branch Parameter.
User defined materials and fluids can be stored in an integrated coefficient memory (user
area). The coefficient memory has to be partitioned first (see section 16.1).
The parameters of user defined materials or fluids can be entered as follows:
• as constants without the extended library (see section 16.2)
• as constants or temperature and pressure dependent functions by means of the ex-
tended library (see section 16.3)
The material and fluid scroll lists displayed in the program branch Parameter can be ar-
ranged (see section 16.5). Shorter scroll lists make working more efficient.

The coefficient memory can be divided into parts for the following material data:
• material parameters:
– transversal and longitudinal sound speed
– typical roughness
• fluid parameters:
– min. and max. sound speed
– kinematic viscosity
– density
• heat flow coefficients (additional fluid parameter)
• steam coefficients (additional fluid parameter)

Introduction
If the extended library is activated, it is possible to enter material and fluid properties as a
function of the temperature or of the pressure and additional fluid parameters (heat flow
coefficients, steam coefficients and concentration coefficients) directly into the transmit-
ter or by means of the program FluxKoef.

The density of a fluid is unknown. If the mass flow rate is not mea-

The measurement of the flow velocity and the volumetric flow rate
will not be affected. However, the value of the mass flow rate will be

The dependence of the material/fluid parameters on the temperature and pressure can
be described
• as constants
• as linear function
• with polynomials of grade 1 to 4
• with customized interpolation functions
In most cases, constants or a linear function are sufficient.
If, e.g., the temperature fluctuations at the measuring point are low compared to the tem-
perature dependence of the material properties, the linearization or the complete neglect
of the temperature dependency will not result in a considerable additional measuring er-
ror.
If, however, the process conditions fluctuate strongly and the fluid parameters depend
strongly on the temperature (e.g., viscosity of hydraulic oil), polynomials or customized
interpolation functions should be used. Contact FLEXIM to find the best solution for the
measuring task.
Customized interpolation functions
Some dependencies are only approximated insufficiently by polynomials. A number of
customized interpolation functions Basics: Y=F(X,Z) are available to interpolate mul-
tidimensional dependencies y = f(T, p). For further information contact FLEXIM.

SuperUser Mode
The SuperUser mode offers the possibility of an advanced analysis of the signal and the
measured values as well as the definition of additional parameters adapted to the mea-
suring point, in order to achieve better measuring values or during experimental work.
Features of the SuperUser mode are:
• Defaults will not be observed.
• There are no plausibility checks when parameters are being entered.
• There is no check whether the entered parameters are within the limits determined by
the laws of physics and technical data.
• The cut-off flow is not active.
• A value for the number of sound paths has to be entered.
• Some menu items that are not visible in the normal the normal mode are displayed.
Attention!
The SuperUser mode is intended for experienced users with ad-
vanced application knowledge. The parameters can affect the nor-
mal measuring mode and lead to wrong measuring values or to a
failure of the measurement when a new measuring point is set up.

example:
profile bound for the laminar flow: 1 500
profile bound for the turbulent flow: 2 500
At Reynolds numbers < 1 500, the flow during the measurement is
regarded as laminar for the calculation of the physical quantity. At
Reynolds numbers > 2 500, the flow is regarded as turbulent. The
range 1 500…2 500 is the transition range between laminar and tur-
bulent flow.
Attention!
The defined profile bounds are still active after the deactivation of
the SuperUser mode.
18.3.2
Correction of the Flow Velocity
After the profile bounds have been defined (see section 18.3.1), it is possible to define a
correction of the flow velocity.
vcor = m . v + n
with
v
– measured flow velocity
m
– slope, range: -2.000…+2.000
n
– offset, range: -12.7…+12.7 cm/s
vcor – corrected flow velocity
All quantities derived from the flow velocity will be calculated with the corrected flow ve-
locity. The correction data are part of the parameter record and will be transmitted to the
PC or printer during the online or offline transmission.
Note!
During the measurement, it will not be displayed that the correction
of the flow velocity is active.

example 1:
Slope: 1.1
Offset: -10.0 cm/s = -0.1 m/s
If a flow velocity v = 5 m/s is measured, before the calculation of the
derived quantities, it will be corrected as follows:
vcor = 1.1 . 5 m/s – 0.1 m/s = 5.4 m/s
example 2:
Slope: -1.0
Offset: 0.0
Only the sign of the measured values is changed.
Note!
The correction data will only be stored when a measurement is
started. If the transmitter is switched off without starting a measure-
ment, the entered correction data will be lost.
Attention!
The correction of the flow velocity is still active after the deactivation
of the SuperUser mode.

Limit of the Signal Amplification
In order to prevent disturbing and/or pipe wall signals (e.g., if the pipe has run empty)
from being interpreted as useful signals, it is possible to define a max. signal amplifica-
tion. If the signal amplification is greater than the max. signal amplification,
• the flow velocity will be marked as invalid. The physical quantity cannot be determined.
• the LED of the measuring channel will light red
• a hash symbol “#” will be displayed after the unit of measurement (in case of a normal
error, “?” is displayed).
Select Special Funct.\SYSTEM settings\Measuring\Miscellaneous. Press
ENTER until the menu item Gain threshold is displayed.

Upper Limit of the Sound Speed
When the plausibility of the signal is evaluated, it will be checked if the sound speed is
within a defined range. The upper limit of the flow velocity for the fluid is calculated from
the greatest of the follwoing values:
• fixed upper value, default: 1 848 m/s
• value of the sound speed curve of the fluid at the operating point plus offset, default off-
set: 300 m/s
In the SuperUser mode, the values can be defined for fluids that are not contained in the
data set of the transmitter. Select Special Funct.\SYSTEM settings\Measur-
ing\Miscellaneous. Press ENTER until the menu item Bad soundspeed is dis-
played.

Press ENTER.
example:
fixed upper value of the sound speed thresh.: 2 007 m/s
offset: 600 m/s
value of the sound speed curve at the operating point: 1 546 m/s
As 1 546 m/s + 600 m/s = 2 146 m/s is greater than the fixed upper
value 2 007, this value will be used as the upper limit of the sound
speed when the plausibility of the signal is evaluated.
