Remote-sealed Differential Pressure Transmitter with Exchangeable Flange Adapter


Advanced Transmitter Remote-sealed Differential Pressure Transmitters (GTX**R series) are used to measure differential pressure (flow rate, fluid level, etc.) of high-temperature or highly corrosive, condensable fluids.The Remote-sealed Differential Pressure transmitter with Exchangeable Flange Adapter model has each size exchangeable flanges, Users can exchange the flange parts at your site according to the applications. Enable to reduce the cost for stocks.


  • Reduces plant downtime for emergencies
  • Reduces cost for stock
  • Reduces space needed for inventory
  • Easy installation with removal flange.
