Problem
Probable Cause
Corrective action
Blank display
Dead battery
Replace battery pack.
Flow rate steadily
reads
zero when there is
flow
Flow is below cutoff
(very low)
Reading will resume when flow increases.
There is air in the meter
Reposition meter for full pipe.
Display reads [ - ]
Meter is installed
backward
Note flow direction arrow, reverse meter.
Flow rate
intermittently
drops when there is
flow
There is air in the meter
Reposition meter for full pipe or rotate to avoid
bubbles.
Erratic reading
Improperly equalized
Check for proper equalization.
Pulsing flow
Use external power source (allows more flow
averaging).
Rapidly changing
conductivity
(chemigation
applications)
Install chemigation line downstream of meter (or
enough upstream for thorough mixing of fluids
before meter).
