Page 16: Sensor Mounting
DFM 5.1 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. Before permanently mounting a Doppler sensor onsite testing is recommended to determine optimum mounting position. - Page 17 DFM 5.1 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 18 Warm temperatures, moisture and vibration will accelerate this process. Dow Corning Silicone Compound #4 as supplied with the DFM 5.1 (and available from Greyline Instruments) is recommended for semi-permanent installations. Page 18...

Page 20: Enclosure Installation
Locate the enclosure within 20 ft (6 m) of the sensor (500 ft -150 m optional). The enclosure can be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel Mount kit from Greyline Instruments. Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to overheating and condensate. - Page 21 DFM 5.1 Doppler Flow Meter FUSE REPLACEMENT 1. Turn OFF power. 2. Loosen cover screw and open. 3. Remove power module. 4. Locate fuse on Power Board. 5. Replace fuse with 2 AMP/ 250V, 5 x 20mm fuse. 6. Reinstall power module into chassis. Page 21...

Page 25: Common Questions And Answers
DFM 5.1 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 26 DFM 5.1 Doppler Flow Meter Can I change the length of the sensor cable? Yes. Technological advances in Greyline Doppler design allow cable lengths up to 500 ft (152 m) with no loss of signal strength. Extended cable (Greyline Option DXC) should be installed in rigid or flexible conduit for mechanical protection.
