SFM 6.1 Slurry Flow Meter
FIELD TROUBLESHOOTING
Possible Causes:
Corrective Action:
METER READING LOWER THAN EXPECTED
Calibration Error

Review UNITS/MODE menu and Pipe ID
Lower flow rate than expected

Investigate pump/valves. Compare velocity
with alternate instrument
Signal not penetrating far enough into the flow stream

Relocate sensor closer to elbows or flow
disturbances
Improper mounting of sensor

Reinstall Sensor with careful application of
Coupling Compound
Pipe is not full

Remount Sensor on vertical pipe
METER READING WHEN THERE IS NO FLOW
Vibration on pipe

Adjust Status / Signal Cutoff setting

Install in another location
Local electrical noise

Ensure all Flowmeter wiring is in METAL
conduit and sensor shield is properly grounded.

Ensure correct power input Ground connection
(<1 ohm resistance).

Ensure 4-20mA Shield connected to Instrument
Ground stud.
Cross talk between two or more SFM 6.1 flowmeters
on same pipe

Refer to Synchronization instructions
Variable Speed Drive interference

Follow Drive manufacturers wiring and
Grounding instructions

Relocate Flowmeter electronics, Sensor and
wiring away from VSD
Sensor cable connections incorrect or loose

Refer to Connections diagram. Disconnect and
reconnect sensor cables ensuring that cable is
properly inserted into terminals and tightened.
