About product

Averaging pitot tube for process gas, steam and liquid metering


  • waste and flue gas measurement
  • natural gas measurement
  • Superheated steam, high, medium and low pressure steam measurement
  • Measurement of gaseous media including air, biogas, flue and sewer gases
  • Heat carrier measurement

Your benefit

  • Operation at low flow rates due to the patented aerodynamic shape of the probe;
  • High measurement stability achieved by optimized probe profile shape;
  • High repeatability of the probe design ensures stable results;
  • High measurement accuracy due to absence of welds on measuring surfaces throughout the flow profile;
  • Availability of built-in computer allowing direct multi-parameter mass flow measurements with full compensation in real time;
  • Integrated temperature sensor arrangement allowing process temperature measurements at the pick-up point without additional tie-in to piping;
  • Less pressure loss than analogues devices in the market.
  • Possibility to install the flow meter without stopping the process;
  • Service life – 10 years
