TROUBLESHOOTING
The M5000 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.
OTE:N 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"
Disconnected signal cable. Check signal cable.
Detector mounted opposite of the main Flow
direction (see arrow on the nameplate).
Turn detector 180° or switch terminal E1 and E2
or reprogram to bidirectional mode.
Coil or electrode cables exchanged. Check cable connections for cross wiring.
Improper low flow cutoff or full scale flow. Replace configuration defaults.
Inaccurate
measuring
Improper calibration.
Check the parameters (detector factor and size)
according to supplied data sheet.
Wrong calibration parameter.
Pipe not fully filled, or air in pipe. Check if meter is completely filled with fluid.
Invalid fluid conductivity.
Purge line to eliminate air bubbles.
Invalid fluid mixture.
Blank display Dead battery. Replace battery.
Flow rate value
known to be wrong
Detector factor. Check value on label.
Deposits on electrodes and/or liner. Check and remove deposits.
Incorrect pipe size programmed. Check size if necessary.
Flow rate indication
unstable
Cable issue. Make sure cable is shielded and not vibrating.
Grounding issue. Make sure meter is properly grounded to a good
earth ground.
Partially full pipe. Make sure pipe is full of fluid.
Air in pipe. Make sure fluid does not contain air bubbles.
Invalid fluid conductivity. Make sure amplifier is not too close to sources of
electrical interference.
