Maintenance and Spare Parts
Maintenance
A program of routine maintenance should be established to ensure the highest
achievable level of performance is maintained. Good housekeeping practices in the area
of the flowmeter are recommended.
Spare Parts
Milltronics recommends a spare inner and outer gasket, sensing plate, and spare
damping fluid be kept on hand.
Contact Milltronics or your distributor for spare parts ordering information.
