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.
