Inline Gas Flow Meter




  • Compact, small design - for use in machines, behind maintenance unit at the end user

  • Optionally with classic analogue signals (4...20 mA and pulse) or digital interfaces such as Modbus RTU, Ethernet (also PoE), M-Bus

  • All interfaces are programmable via the display

  • Current consumption in m³/h, l / min, ...

  • Total consumption (meter reading) in m³, l, kg

  • Temperature measurement

  • Optional: Pressure measurement





  • Robust impact-proof aluminum die cast housing for the outdoor area
  • IP 67
  • All medium-touching parts made from stainless steel 1,4571
  • On request with ATEX approval ATEX II 2G Ex d IIC T4 (up to 120 °C)
  • On request with DVGW approval for natural gas 
  • Pressure rang up to 16 bar, special version up to 40 bar
  • Temperature range up to 180 °C
  • No moving parts, no wear out
  • Sensor tip very robust, easy to clean
  • Housing turnable, display turnable by 180°


  • Digital interfaces such as Modbus RTU, Ethernet (PoE) and M-Bus enable connection to higher-level systems such as energy management systems, building management systems, SPS
  • Units freely selectable via keys at the display m³/h, m³/min, l/min, l/s, kg/h, kg/min, kg/s, cfm
  • Compressed air counter up to 1.999.999.999 m³. Resetable to „0“ via keypad
  • Analogue output 4...20 mA, pulse output (galvanically separated)
  • High measuring accuracy also in the lower measuring range (ideal for leakage measurement)
  • Negligibly small loss of pressure
  • Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
