Troubleshooting
Problem: Product flows through meter but register does not record correctly.
Probable Cause:
1. Adjuster not properly calibrated.
2. Incorrect gear plate or gear ratio has been installed.
3. Meter is damaged.
4. There is air in the system
Problem: No flow through meter.
Probable Cause:
1. Faulty pump.
2. Valve not open or not functioning.
3. Meter “frozen” due to buildup of chemical “salts” or foreign material inside the metering chamber. To correct, clean
the meter and inspect for damage.
Problem: Meter runs too slowly.
Probable Cause:
1. Valve internal mechanism faulty. Valve does not open fully.
2. Meter gears or rotors partially “salted” enough to slow up rotation of parts. To correct, clean the meter.
3. The strainer basket is partially clogged.
Problem: The meter counts down (the numbers decrease).
Probable Cause: It is necessary to reverse the direction of flow by reversing the adjuster drive gear. See Meter Start
Up & Operation on Page 12 of this manual.
Problem: Product flows through the meter but the register does not operate.
Probable Cause:
1. Check the packing gland and gear train.
2. If all meter parts are moving, the problem is in the register. Faulty registers should be checked and repaired by a
trained technician.
3. Remove the register from the meter. If all meter parts are moving but the output of adjuster assembly is not,
adjuster is worn and must be replaced.
4. If totalizer numbers (small numbers) on the meter are recording, but the large numbers are not moving, the register
needs repair.
5. The packing gland gear is not turning. The drive blade may be sheared. Replace the packing gland. This may be
caused by starting the flow too rapidly.
