3 General Principles

FLUXUS F60x

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.

transducers

transmitter

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).

UMFLUXUS_F6V4-5-1EN, 2016-05-11

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_

k_a =

————

sin



The acoustic calibration factor k_a 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:

FLUXUS F60x

Fluid mechanics correction factor k_Re

With the fluid mechanics correction factor k_Re, 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

Mass flow rate

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 = k_Re · k_a ·

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:

t

Depending on the signal attenuation, the error of measurement in the NoiseTrek mode

can be greater than in the TransitTime mode.

3 General Principles

3.2.4

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.

3.3

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

(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).

5 Selection of the Measuring Point

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

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.

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.

section 11.6.2, it is recommended to write down the sound speed for the next measure-

ment. By doing this, it will not be necessary to repeat the fine adjustment.

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

Damping Factor

Each displayed measured value is the floating average of all measured values of the last

x seconds, where x is the damping factor. A damping factor of 1 s means that the mea-

sured values are not averaged as the measuring rate is approx 1/s.

The default value of 10 s is appropriate for normal flow conditions. Values which fluctuate

strongly due to of a higher flow dynamic, require a higher damping factor.

Measurement of High Dynamic Flows (FastFood Mode)

The FastFood mode allows to measure flows with high dynamics.

A continuous adaptation to changing measuring conditions which takes place in the nor-

mal measuring mode is only partially realized in the FastFood mode.

• The sound speed of the fluid is not updated. The last measured value of the sound

speed before toggeling to the FastFood mode is used.

• A change of measuring channel is not possible. In a multi-channel measurement, the

measurement stops on all further channels during the activation of the FastFood mode.

• The outputs of the FastFood mode activated channel can still be used.

• Outputs for further channels (multi-channel measurement) are not updated.

• The measured values are stored with the storage rate of the FastFood mode (see sec-

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.

14 Data Logger and Transmission of Data

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.

Select a storage rate or EXTRA. Press ENTER.

• storing of the totalizers

• storing of the signal amplitude

• storing the sound speed of the fluid

• storing of the diagnostic values

• start of Storing

• acoustic signal during the storing

Ringbuffer

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.

• If the ringbuffer is deactivated, the storing of measured values will be stopped.

Select the behavior of the ringbuffer. Press ENTER.

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.

Partitioning of the Coefficient Memory

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)

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.

Enter only the properties needed for the measuring task.

example:

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

sured, any constant value can be entered as the density.

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

wrong.

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.

• 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.

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.

v_cor = m ^. v + n

with

– measured flow velocity

– slope, range: -2.000…+2.000

– offset, range: -12.7…+12.7 cm/s

v_cor – 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:

v_cor = 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.

Enter for each measuring channel the max. signal amplifi-

the upper line in the program branch Measuring. If the

actual value of the gain is higher than the max. gain, the

actual value is displayed with →FAIL!.

Attention!

The limit of the signal amplification is still active after the deactiva-

tion of the SuperUser mode.

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
