differential pressure flow meter / Venturi / for air / insertion
MVR/FVR Arthur Grillo GmbH



  • Technology:

    differential pressure, Venturi

  • Fluid:

    for air

  • Other characteristics:


  • Volumetric flow rate:

    Min.: 40 m³/h (1,412.6 ft³/h)

    Max.: 90 m³/h (3,178.3 ft³/h)


The venturi nozzle is made with an inlet profile as per ISA according to DIN EN ISO 5167. The flow which is important and favorable for metering is achieved through the specific deformation process of the thermoplastic material. It allows for an exact fitting as well as for extremely smooth surfaces for ideal flow conditions without any costly rework.The pressure relief valves have 4-5 individual bore holes in the cylindrical neck which open out into a ring chamber. For further evaluation, indicators (DA 2000) with a scale in m/h or measuring transducers (DS 200) for remote transmission of the measuring signal are available. The exact design of the indicators or the measuring transducers depends on the design data which are to be clarified beforehand.
