Weld-on adapter with ball valve for Sensyflow FMT400-VTS

Versions featuring a ball valve enable the flowmeter sensor to be installed and disassembled at
low gauge pressures in the pipeline with minimal gas leakage.
Install the weld-on adapter as described in Section 4.3.
WARNING
During welding, the gaskets in the ball valve may overheat.
This can lead to the measuring medium escaping in an uncontrolled manner.
This can result in severe injuries or death.
Disassemble the ball valve prior to welding.
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 - Potential damage to parts!
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.
