Rheonik RHM 60 Large Coriolis Flow Meter

  • Withstands a high pressure rating of up to 490 bar.
  • Precise measurements due to 0.1% mass flow uncertainty.
  • Measuring range of between 60 and 3000kg/min.

Flow rate

The RHM60 is a large size Coriolis sensor with a maximum density rate of 3000kg/min and a minimum accurate density rate of 60kg/min.


The torsion oscillator design provides accurate measurements with low mass flow uncertainty at 0.1% and high consistency with repeatability being better that 0.05%.

Temperature and pressure ranges

Wide fluid temperature range of between -196°C and 350°C means it can be used in high temperature applications like asphalt and bitumen. Other applications include terminal transfer, reactor charging and plant balance.


The sensor enclosure is produced as standard out of stainless steel but can be changed to 316 stainless steel. The terminal box is made from epoxy coated aluminium but can also be made from 316 stainless steel.

A variety of wetted materials are available including Alloy C22, Superduplex and 316Ti.


The sensor enclosure is protection class IP65 but there is the available option of IP66/NEMA4X. The sensors are approved for use in hazardous zones having been given ATEX/IECEx approval for zones 0, 1 and 2. There is also North American Approval for Class I, Div. 1 and groups ABCD.
