Troubleshooting

Trouble Corrective Action

No Flow through meter or high pressure drop across meter

Solidied 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 ush 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 nd 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 ow

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 ow does not agree with expected readings

Air in the line

Indicator not calibrated properly

Excessive reverse ow 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 ow. An incorrect

ow total can be reported if the pumping causes a

ow and ebb of greater than 1 meter revolution.
