SERVICE AND MAINTENANCE
11. Carefully direct a low pressure jet of air (5 psi [34.5 kPa]) through flow meter in the direction of flow and again
in the opposite direction to verify that the turbine spins freely.
12. If there is drag, loosen the stud on the bearing hub 1/16 turn until the turbine spins freely.
13. If turbine spins freely and the cables have checked out, but the flow meter still is not reading properly, verify
that the sensor is threaded all the way into the flow meter body, and the orientation groove on top of the
sensor is parallel with flow meter body. if flow meter still does not read, replace sensor assembly.
14. Re-connect the flowmeter to the system plumbing. Ensure gaskets on couplings slide over the piping and
flowmeter body, centering gasket between components. Lubrication with soap may be required. Attach coupler
clamp and re-torque hardware to 80-100 ft-lbs.
