Section 10 Cleaning and Maintenance
Maintenance of the 800 Series Metering flow switch is normally limited to cleaning the chamber in which
the rotor spins and an annual recalibration.
Cleaning the 800 Series flow sensor
The frequency of cleaning will vary with the type and cleanliness of the liquid being run through the flow
meter. In most cases, annual cleaning immediately prior to recalibration is sufficient.
Tools required:
Wrenches to disconnect the flow meter from your flow circuit.
A flat screw driver.
Soft cleaning cloth
Alcohol, water or a dilute detergent solution.
Cleaning the 800 Series Flow Sensor
1. Turn OFF the liquid flow in your flow circuit
and remove the 800 Series sensor from
your system. Place the sensor on a clean
surface.
2. Remove the 6 screws securing the
faceplate.
3. Remove the faceplate from the flow meter.
