  • Page 19: Transducer Mounting Location

    PTFM 1.0 Portable Transit Time Flow Meter TRANSDUCER MOUNTING LOCATION The position of the transducer is one of the most important considerations for accurate Transit Time flow measurement. The same location guidelines apply to Transit Time as most other types of flow meters.

  • Page 20: Transducer Mounting

    PTFM 1.0 Portable Transit Time Flow Meter TRANSDUCER MOUNTING Prepare an area 2" wide by 4" long (50mm x 100mm) for transducer bonding by removing loose paint, scale and rust. The objective of site preparation is to eliminate any discontinuity between the transducer and the pipe wall, which would prevent acoustical coupling.

  • Page 26: Common Questions And Answers

    PTFM 1.0 Portable Transit Time Flow Meter COMMON QUESTIONS AND ANSWERS The pipe vibrates. Will it affect the flow meter? Common vibration frequencies are far lower than the sonic frequencies used by the Greyline flow meter, and will not normally affect accuracy or performance. However, applications where very weak Transit Time signal is present (when sensitivity is adjusted to maximum and signal strength is low), accuracy may be affected by pipe vibration, or the flow meter may show readings under no-flow conditions.
  • Page 27 PTFM 1.0 Portable Transit Time Flow Meter What is the purpose of the Signal Strength Display? The primary function of the signal strength display is to assist as a feedback when mounting transducers. Signal Strength can also be a useful diagnostics tool when troubleshooting problems with an installation. A low signal strength (<...
