Trial operation
Start trial operation (without flow meter); open the stop valves

when doing this.
Carry out a pressure test in the plant.
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 the pipework is tight and clean and that there are no foreign
bodies in the pipe that could damage the flowmeter.

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.
