Trial operation
Start trial operation (without flow meter); open the stop valves slowly when doing this.
•
Carry out a pressure test prior to meter installation
•
Check for leaks and tightness of all bolts
•
Flush the pipework until clean (flow meter out of pipeline)
•
Release the pressure and stop the system again
This trial operation ensures that all pipework is tight, clean and free of foreign matter that could
damage the flow meter.
Installing the meter in the pipe
Remove the protection plugs or caps from the flow meter (inlet and outlet).
Insert the flow meter into the pipeline in the prescribed position and flow direction. The arrow on
the flow meter should correspond with the direction of flow. Install mating flanges parallel and
without tension in the pipe.
