1) 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.
4.4 Weld-on adapter with ball valve for Sensyflow FMT500-IG
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.
DANGER
The welding adapter with ball valve is not approved for use in potentially explosive
atmospheres.
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.
