Possible Causes:

Corrective Action:

Coupling compound washed out, or sensor loose on
pipe



Remount sensor



Use Dow Corning Silicone #4

METER READING TOO HIGH

Calibration error



Review

UNITS/MODE

menu and Pipe

ID

Vibration or noise on the pipeline



Install in another location.

Pipe is not full



Remount Sensor on vertical pipe

Nearby velocity increasing device (pump, valve, orifice
plate)



Relocate sensor >30 pipe diameters from
velocity increasing device

Variable Speed Drive interference



Follow Drive manufacturers wiring and
Grounding instructions



Relocate Flowmeter, Sensor and wiring away
from VSD

BATTERY CONDITIONING



To restore or condition your PDFM 5.1 battery
for best performance fully discharge the unit
