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

  • Saving 5-15% on electricity bills when replacing constriction devices with a pito tube by reducing the pressure drop from 20-30% to 5-8%;
  • Increasing the service life and lifetime of a steam turbine or pump by 20%, due to reduced inlet pressure;
  • Reduction of expences by 4 times for the removal/installation of the flow meter, proving, transportation, replacement fund, and for repairing;
  • Integrated computer in the explosion-proof casing, which is ready for volume calculations without additional equipment;
  • Installation/dismounting without interruption of the process;
  • Simulation proving method;
  • Flow compensation by temperature and pressure;
  • Metering on gas pipes of complex shape;
  • Metering of high-temperature gases up to +710°C up to 25 MPa;
  • Metering of air emissions from pipelines up to 15 m in diameter.
