SFM 6.1 Slurry Flow Meter SENSOR MOUNTING LOCATION The position of the sensor is one of the most important considerations for accurate slurry flow measurement. The same location guidelines apply to slurry as most other types of flow meters. Before permanently mounting a slurry sensor onsite testing is recommended to determine optimum mounting position.
Page 17
SFM 6.1 Slurry 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.

Warm temperatures, moisture and vibration will accelerate this process. Dow Corning Silicone Compound #4 as supplied with the SFM 6.1 (and available from Greyline Instruments) is recommended for semi-permanent installations. Page 18...
SFM 6.1 Slurry Flow Meter 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). Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to overheating and condensate.

SFM 6.1 Slurry 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...

(Greyline Option DJB). BNC coaxial connectors (TV cable type) are not recommended for cable splices. Does the SFM 6.1 require periodic recalibration? SFM 6.1 calibration does not drift over time. The solid state sensor has no moving parts to wear and affect calibration. The ultrasonic flow technique generates an ultrasonic signal proportional to the velocity of flow.
