Rheonik RHM 02 03 04 Small Coriolis Flow Meter

  • Maximum pressure rating up to 1379 bar
  • 0.10% mass flow uncertainty
  • Flow range between 25g/min to 10kg/min

The RHM 02, 03, 04 measure flows within the range of 25g/min to 10kg/min.

The high pressure ratings of up to 1379 bar and a wide fluid temperature range of -196°C and 350°C mean that the meters can be used in a variety of applications such as high pressure gas dispensing and polyurethane processes.

Consistent accuracy is given by the torsion oscillator design which makes it resistant to external vibrations.

Precise measurements are given by mass flow uncertainty which is low at 0.1% and repeatability is better than 0.05%.


The sensor enclosure box is stainless steel with a coated aluminium terminal box. 316 stainless steel is available to be used for both.

Standard enclosures are protection class IP66, NEMA4. However, IP68 and IP69K along with NEMA4X are possible options.

Meters are ATEX/IECEx approved for use in zone 0, 1, 2 and are North American Approved for use in Class I, Div.1 and Zone 2.


  • RHM02 measures between 2kg/min and 0.05kg/min.
  • RHM03 measures between 0.1kg/min and 5kg/min.
  • RHM04 measures between 0.2kg/min and 10kg/min. Pressure ratings up to 1379 bar and a fluid temperature range of between -196°C and 350°C.
