Page 19: Sensor Mounting
PTFM 1.0 Portable Transit Time Flow Meter SENSOR MOUNTING LOCATION The position of the sensor 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 PTFM 1.0 Portable Transit Time Flow Meter SENSOR MOUNTING Prepare an area 2" wide by 4" long (50mm x 100mm) for sensor bonding by removing loose paint, scale and rust. The objective of site preparation is to eliminate any discontinuity between the sensor 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 ISO 9000 or similar quality management systems may require periodic and verifiable recalibration of flow meters. PTFM 1.0 Flow Meters may be returned to Greyline for factory calibration and issue of a new NIST traceable certificate. Refer to the ‘Product Return Procedure’ section of this manual for return instructions.
