Problem
Probable Cause
Try...
No pulse output
Unit not grounded
Connect to earth ground.
Below minimum flow cutoff
Check the Presence of Flow LED (see
page 15).
Flow reversed
Note flow direction arrow, reverse
direction to meter.
Output connections reversed
Change output connections.
Pipe not full
Check plumbing.
Excessive electrical noise
Check for proper electrical wiring.
No power
Check for power across power input
terminals.
Power reversed
Reverse connections
Fluid conductivity <20 µS/cm
Select another flow meter.
Output pulses incorrect
Missing or incorrect ground wire
Check for proper ground.
Incorrect depth setting
Check depth setting (see page 7).
Fluid conductivity <20 µS/cm
Select another flow meter.
Empty pipe
Check for full pipe or install meter in
vertical position.
Not enough straight pipe
Check for air pockets or turbulence.
Refer to Installation section earlier in
this manual.
Excessive electrical noise
Check for proper electrical wiring.
Jumpy readings
Rapidly changing conductivity (in
chemical injection or fertigation
applications).
Install chemical injection line
downstream of magmeter (or far
enough upstream to allow complete
mixing of fluids before meter)
