Rotary Meter


The OMEGA VI rotary gas meter of vemm tec Messtechnik GmbH:

is a positive displacement meter for volume and flow rate measurement. The meter is suited for measuring clean, dry, and non-corrosive gases like natural gas, propane, butane, air, nitrogen, and others.


The OMEGA VI is used for highly accurate measurement with a very large rangeability. The measured actual volume is often converted into the volume at base conditions. The OMEGA VI is therefore prepared for use in combination with an electronic volume converter. The OMEGA VI rotary gas meter complies with all national and international requirements for gas meters – MGR (MID), DGRL (PED), DIN EN 12480, ISO, OIML etc.


The OMEGA VI can be used for the following applications:

  • Meter sizes G25 to G250

  • Flow ranges 0.6 – 480 m3/h

  • Nominal diameters DN 50 to DN 100

  • Pressure stages PN10/16 and ANSI 150#

  • Pmax 20 bar

  • Temperature range -25 °C to +55 °C (-10°C to 55°C )

  • Measuring ranges up to 1:200

  • Measuring accuracy +- 1% / +- 2%

  • Compact housing of aluminum (DN50) or ductile iron (DN50 to DN100)

  • Service interval of 8 years

  • Suitable for use in horizontal and vertical position

  • Stable housing

  • Compact mounting (to the wall)

  • No upstream and downstream pipe sections required

  • HF sensors possible (optionally)

  • Higher temperature resistance (HTB) according to EN 12480
