ClampOn DSP Topside PIG Detector

Benefits

The ClampOn DSP PIG Detector detects the PIG passing through the pipe by use of passive acoustic technology – any PIG, any pipe, any flow!

There is a range of options available to indicate a PIG passing:

  • Local light (reset) at the PIG detector
  • Through a voltage free contact
  • Through a data output signal connected to either a PC with PIG detector software or a control system (MCS).

With a graphical display of the received signal from the PIG detector, the customer will also have information on the amount of debris passing in front or after the PIG.

The ClampOn DSP PIG Detector, available in topside and subsea versions, is a more compact and user friendly unit than other similar instruments on the market. It is easier to install in the field and small and compact enough to move to other locations.

DSP involves complete digitalization of the system and the elimination of analogue filters. This technology is increasingly used in a wide range of “smart electronic devices” as it provides sufficient capacity to perform advanced signal processing tasks in real time. Devices include medical diagnostic instruments, radar and sonar systems and mobile phones. ClampOn is the only manufacturer of PIG detection systems to use DSP, which enables the sensor to operate in several frequency ranges simultaneously, eliminating the danger of the detector being triggered by noise sources other than PIGs.

The PIG detector can be interfaced with the control system using either:

  • Digital RS485 interface
  • Analogue 4-20mA interface
  • Digital output, VFC (Volt Free Contact)

Detecting the PIG passing is done by detection criteria’s in the detector itself or using our computer software. There are also two sets of detection methods available, fixed threshold and percentage of signal. The latter is often used with unstable flow conditions.

It is recommended to use the digital interface (RS485) and a computer running our software for following reasons:

  • Detection criteria’s can easily be set in the software by an operator.
  • All data will be logged and all PIG passing will be recorded and time stamped.
  • Trends will be available for correct calibration of detection.
  • Method of detection can quickly be changed if needed.
