Product flows through meter
but register does not record
correctly
This may result from the following:
· Adjuster not properly calibrated.
· Incorrect gear plate or gear ratio has been
installed.
· Air is in the system.
No flow through meter
This may result from the following:
· Faulty non-functioning pump.
· Valve not open or not functioning.
· Meter “frozen” due to build-up of chemical “salts”
or foreign material inside metering chamber.
Clean the meter and inspect for damage.
Meter runs too slowly
This may result from the following:
· Valve internal mechanism faulty. Valve does not
open fully.
· Meter gears or rotors partially “salted” enough to
slow up rotation of parts. Clean the meter.
· Downstream restriction.
· Clogged strainer basket.
The meter counts down in
reverse (the meter numbers
decrease)
Reverse the direction of flow by reversing the
adjuster drive gear. See Reversing the Meter
