If the flow in the pipe has pulsation, the measurement accuracy may be affected.

When installing, recommended tightening torque at piping is 5 ± 2 N · m for DN05 and DN10, and 7 ± 2 N · m for DN20. Also,

Keep warm the entire system where the fluid can freeze in winter. If the fluid leaks due to freezing, the measurement accuracy
may be affected.

Avoid installing the flowsensor where it is exposed to excessive pressure such as water hammer.

10 An air pocket in the flowsensor affects its measurement accuracy. Use the flowsensor with its measurement chamber filled withthe fluid. Air passing through the chamber also affects the accuracy. Be careful not to allow air to ingress.
