MAINTENANCE AND REPAIR
5.1 ROUTINE
MAINTENANCE
The e-FlowMeter does not have any moving mechanical parts and so is not affected by fatigue wear from mechanical stress.
The system should be inspected routinely for leaks. It is recommended the equipment be turned off during inspection.
5.2
CLEANING DEBRIS FROM MEASUREMENT CYLINDER
If the reading from the e-FlowMeter begins to act in an unreliable manner, then the measurement cylinder should be
inspected and cleaned out to ensure proper operation.
Procedure:
1) Close the shut-off valves to stop the flow of water.
2) Disconnect all wiring.
3) Go through the removal steps (chapter 3.3.3 «Removal
instructions») to remove the e-FlowMeter from the
Control Valve, using the Insertion Tool.
4) With the sensor still removed from the threaded insert,
inspect the measurement cylinder; look specifically for
debris caught on the bluff body, as shown on the
figure.
5) Use pick or small screw driver and tweezers to remove
all of the debris from the measurement cylinder, bluff
body and anywhere else that is has accumulated.
6) Reinstall e-FlowMeter according to chapter 3.3.2
«Installation».
5.3
DEALING WITH SENSOR TIP DAMAGE
If the sensor tip is bent, broken or damaged in the course of the handling or installation, the e-FlowMeter will not function
properly. The sensor should be straight with respect to the sleeve. Since it is designed to sense micro-motion, if the sensor
is forced to enough to detect the movement with the naked eye, it may have been damage. In that case, contact CLA-VAL
Customer Service.
