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

Variable Speed Drive interference

• Follow Drive manufacturers wiring and

Grounding instructions

• Relocate Flowmeter, Sensor and wiring away

from VSD

Sensor connections incorrect

• Refer to Connections diagram

METER READING ERRATIC

Sensor mounted too close to valve, pump or
elbow

• Change sensor placement. Recommended 6-10

diameters from elbows, and 30 diameters from
pumps, controlling valves, orifice plates,
nozzles or open pipe discharge

NO FLOW INDICATION

Not enough suspended particles or gases in the
fluid

• Relocate sensor in more turbulent pipe section.

Mount sensor at 12 o'clock position on
horizontal pipe
