Proper handling and care will extend the life and
service of the meter.
Turbine Rotor
-
The meter is virtually maintenance-free. However,
it is important the rotor moves freely. Keep the meter
-
clean and free of contaminants.
If the rotor does not turn freely, apply a penetrating
lubricant on the rotor, shaft, and bearings. Remove
any debris or deposits from the rotor using a soft
-
brush or small probe. Be careful not to damage the
turbine rotor or supports.
CAUTION : Blowing compressed air through the
turbine assembly could damage the rotor.
