  • Page 18: Transducer Mounting

    TTFM 1.0 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 19 TTFM 1.0 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 27: Common Questions And Answers

    TTFM 1.0 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 28 Does the TTFM 1.0 require periodic recalibration? No. TTFM 1.0 calibration does not drift over time. The solid state transducer has no moving parts to wear and affect calibration. All Greyline timing/counting circuits use crystal-controlled frequency references to eliminate any drift in the processing circuitry.
