9. Maintenance
Flowmeter maintenance precautions:

Remove/disconnect power to the flowmeter.

Ensure that flow supply to the meter is turned off and the system is not
under pressure.

Completely drain the flowmeter

Confirm that any signal output(s) will not affect the system when de-
energized or removed from the circuit.
Oval gear positive displacement flowmeters are mechanical by nature. A periodic
maintenance/inspection schedule is suggested for an extended service life.
Follow the guidelines within this user manual for the maximum flowmeter
performance.
The maintenance/inspection schedule should be determined based off of
application factors such as media type (abrasiveness, lubricity, and/or chemical
compatibility), flow rate, and operating/maximum temperature and pressure.
