Troubleshooting
Trouble
Corrective Action
No Flow through meter or high pressure drop across meter
Solidified material blocking rotation
Debris blocking rotation
Meter broken
Heat meter to melt material
Remove plumbing base, inspect crankshaft and piston
rods for damage. If intact flush the inside of the meter
and try to work pistons free by rocking the crankshaft
back and forth gently with a small rod or retracted pen
If you find damaged parts in the meter, return the
meter to the factory for repair
Fluid is passing through the meter, but there is no indication of flow
Improper hook-up of transmitter
Meter not turning
Verify that DC power is present at the PCA. Use a multi-
meter to measure the transmitter output independent
of the display or PLC
Remove transmitter from meter and place a paper clip
against the magnet shield. Clip should be drawn to
magnet inside of the meter and move with the meter’s
rotation
Indicated flow does not agree with expected readings
Air in the line
Indicator not calibrated properly
Excessive reverse flow in system
Air bubbles displace the meter just as a liquid would. If
you are over-reporting, verify that there is no air in the
lines.
Verify the K-Factor for the meter in use and compare
this value to the setting used in the display.
Max transmitters have anti-dither functions which can
buffer up to 1 revolution of reverse flow. An incorrect
flow total can be reported if the pumping causes a
flow and ebb of greater than 1 meter revolution.
