Rheonik RHM 20 Medium Coriolis Flow Meter

We aim to respond within 1 hour

Measures flow rates between 3kg/min up to 300kg/min
Able to operate at high pressures with a pressure rating of up to 799 bar.
Highly accurate measurements at 0.15% mass flow uncertainty and 0.05% repeatability.

Accuracy

The RHM20 from Rheonik offers accurate measurements to 0.15% mass flow uncertainty from a wide range of mass flow in-between 3Kg/min up to 300Kg/min.

Temperature and pressure ranges

A wide temperature rating from -196°C to 350°C means that the RHM20 can be used for an array of applications such as general flow control, plant balance and package and container filling. High pressure ratings of up to 799 bar mean that it can be used for more extreme applications.

The unique torsion oscillator design means that the RHM20 is very robust with a long lifetime as there are no moving parts to fail. It also means that the measurements are even more accurate due to their resilience from noise and vibration.

Materials

Meters can be fitted from a selection of wetted materials such as 316Ti, Alloy C22, Tantalum and Superduplex. Seals are manufactured out of PTFE.

Sensors are enclosed in stainless steel as standard, and the terminal box is constructed with epoxy coated aluminium also as standard. 316 stainless steel terminal and enclosure are an option.

Approvals

The RHM20 is approved for use in hazardous zones. It has been approved by ATEX/IECEx in zones 0, 1, 2. North American Approvals have also been granted for Class I, div.1 and Groups ABCD.
