Installation & Operation Manual
Troubleshooting
The M-2000 mag meter is designed for many years of optimal performance. However, should it malfunction, there are certain
things that we recommend you check before contacting our Technical Support department or your local Badger Meter
Representative.
Note: If the fluid measured has a high concentration of conductive solids, deposits may accumulate on the
internal liner walls and electrodes. These deposits will cause a reduction of the measuring output. Thus, Badger
Meter recommends that you remove the meter and inspect the liner and electrodes after six months. If deposits
are found, remove them with a soft brush. Repeat inspection process every six months or until an appropriate
inspection cycle can be established for the specific application.
Other general conditions include:
Description Possible Cause Recommended Action
Flow is present but display
is "0"
Digital input is holding ow.
Disconnected signal cable.
Detector mounted opposite of the main
ow direction (see arrow on the nameplate).
Coil or electrode cables exchanged.
Improper low ow cuto or full scale ow.
Check signal cable.
Turn detector by 180° or switch terminal E1 and E2 or
reprogram to bidirectional mode.
Check cable connections for cross wiring.
Verify digital input conguration.
Replace conguration defaults.
Inaccurate measuring Improper calibration.
Wrong calibration parameter.
Pipe not fully lled, or air in pipe.
Invalid uid conductivity.
Invalid uid mixture.
Restore calibration defaults.
Check the parameters (detector factor and size)
according to supplied data sheet.
Check if meter is completely lled with uid.
Purge line to eliminate air bubbles.
No display No power.
Incorrect power.
Bad wiring connections.
Blown fuse.
Apply power.
Check power value.
Replace fuse. (2 amp, 250 VAC, slow blow (5 x 20 mm)
Check display ribbon cable.
Flow rate value known to be
wrong
Detector factor.
Deposits on electrodes and/or liner.
Incorrect pipe size programmed.
Check value on label.
Check and remove deposits.
Check size if necessary.
Flow rate indication
unstable
Cable issue.
Grounding issue.
Partially full pipe.
Air in pipe.
Amplier location - outside electrical.
Invalid uid conductivity.
Make sure cable is shielded and not vibrating.
Make sure meter is properly grounded to a good earth
ground.
Make sure pipe is full of uid.
Make sure uid does not contain air bubbles.
Make sure amplier is not too close to sources of
interference. Electrical interference.
