Badger Meter ModMAG M Series - Troubleshooting

TROUBLESHOOTING
The 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.
If the fluid measured has a high concentration of conductive solids, deposits may accumulate on the internal liner walls and
electrodes. These deposits 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.
Description Possible Cause Recommended Action
Rollover warning • A rollover warning occurs when the display
totalizer can no longer represent the current
value within the totalizer. A rollover warning is
dependent on the number of dials, resolution and
the unit of measure.
• Increase number of dials
• Reduce resolution or
• Clear totalizers
Flow is present but display is“0” • Digital input is holding flow.
• Disconnected signal cable.
• Sensor mounted opposite of the main flow
direction (see arrow on the nameplate).
• Coil or electrode cables exchanged.
• Improper low flow cutoff or Full Scale Flow.
• Verify digital input configuration.
• Check signal cable.
• Turn sensor by 180° or switch terminal E1 and E2 or
reprogram to bidirectional mode.
• Check cable connections for cross wiring.
• Replace configuration defaults.
Inaccurate measuring • Improper calibration.
• Wrong calibration parameter.
• Pipe not fully filled, or air in pipe.
• Invalid fluid conductivity.
• Invalid fluid mixture.
• Restore calibration defaults.
• Check the parameters (sensor factor and size) according
to supplied data sheet.
• Check if meter is completely filled with fluid.
• Purge line to eliminate air bubbles.
No display • No power.
• Incorrect power.
• Blown fuse.
• Bad wiring connections.
• Apply power.
• Check power value.
• Replace fuse (2 amp, 250V AC, slow blow 5 × 20 mm).
• Check display ribbon cable.
Flow rate value known to
bewrong
• Sensor 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.
• Transmitter location – outside electrical.
• Invalid fluid 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 fluid.
• Make sure fluid does not contain air bubbles.
• Make sure transmitter is not too close to sources of
electricalinterference.
BEACON AMA displays multiple
estimated flow occurrences for
meters connected to ORION
Cellular LTE endpoints.
• ORION Cellular LTE endpoints require
additionalresistance.
• Add a 15K resistor to the M2000 meter terminal block.
