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.
