S430 Pitot Tube Flow

SUTO-iTEC flow sensor S 430

The sensor features long term stability , wide turn-down ratio and good temperature stability. It can be used in compressed air and non-corrosive gases.

Through a 1/2” G-type ball valve the sensor can be inserted into the pipe under pressure.
Various output signals allow the sensor to be connected to SUTO-iTEC displays and/or third party displays and PLCs.


S 430 measures:
– Standard flow and consumption
– Actual velocity
– Pressure
– Temperature


Product features

  • Flow and consumption measurement in wet air or high mass flow / velocity applications
  • Measurement at compressor outlet possible
  • Tube diameters of 1’’ to 10’’. Other diameters on request
  • Insertion type, easy installation under pressure through ball valve possible
  • High temperature applications up to 200 °C
  • No mechanical wear parts
  • All parts which are in contact with flow medium are made of stainless steel
