Before the flowmeter sensor is installed, the ball valve must be opened completely. Then, the
flowmeter sensor can be installed along with the appropriate gasket and screwed into place.
Before disassembling the flowmeter sensor, ensure that the pipeline has been depressurized.
Then, you can release the screws on the flange, remove the flowmeter sensor and close the
ball valve.
NOTICE - component damage!
Closing the ball valve before you remove the flowmeter sensor can seriously damage the
protective cage or the sensor elements.
Do not close the ball valve until the flowmeter sensor has been removed.

This maximum pipe diameter specification is only valid when installing the sensor unit centrically in the pipe.
For larger diameters or angular ducts a non-centric sensor position is taken into account for calibration.
IMPORTANT (NOTE)
Deviations from the stated dimension and position tolerances cause additional measuring
uncertainty.
