Page 14: Sensor Mounting Location
PDFM 5.1 Portable Doppler Flow Meter SENSOR MOUNTING LOCATION The position of the sensor is one of the most important considerations for accurate Doppler flow measurement. The same location guidelines apply to Doppler as most other types of flow meters. - Page 15 PDFM 5.1 Portable Doppler 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 16 Warm temperatures, moisture and vibration will accelerate this process. Dow Corning Silicone Compound #4 as supplied with the PDFM 5.1 (and available from Greyline Instruments) is recommended for semi-permanent installations.

Page 20: Common Questions And Answers
PDFM 5.1 Portable Doppler 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 Doppler 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 21 Does the PDFM 5.1 require periodic recalibration? PDFM 5.1 calibration does not drift over time. The solid state sensor has no moving parts to wear and affect calibration. The Doppler flow technique generates an ultrasonic signal proportional to the velocity of flow.
