The transmitters KPT can be installed in a connection point of the under pressure pipe.
It is recommended that the combination of a closing valve to facilitate the operations of mechanical installation or maintenance.
The driof the Zero caused by the installation position can be easily eliminated by the calibration trimmer Zero.
If you want to calibrate the Zero or Span unscrew the top of the transmitter body.
