Thermal Mass Flowmeters – Master-Touch MP – MPNH

Category Brand


The Thermal Mass Flowmeters measure the mass flow rate of the flowing gas without the aid of moving parts and are not susceptible to variations in pressure or process temperature.

Thanks to the Thermal Mass technology, the Thermal Mass Flowmeters can measure the mass of the gas flow per unit time, without the influence of temperature and pressure on the meter.

Each Thermal Mass Flowmeter is calibrated to the required flow rate and pre-compensated for temperature.

The Thermal Mass Flowmeters are suitable for applications involving, among others: Argon, Nitrogen, Biogas, CO2, Digester, Helium, Gas Torch, hydrogen, hydrocarbon mixtures, Methane, Natural Gas, Oxygen.

The Master-Touch MP series is designed for industrial applications in hazardous areas, while the Master-Touch MPNH series is suitable for Non Hazardous area applications. Both series feature various models:

  • For insertion and with extraction valve
  • With threaded, flanged and tri-clamp pipe
  • With integrated and blind electronics
  • With integrated electronics and local display
  • With integrated electronics and remote display
