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totalizer can no longer represent the current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 .
