Rheonik Coriolis Mass Flow Meter

The RHM 12 is an economical  mass flow meter meter which has been in production for over 15 years. This flow meter has been optimized for applications which require extreme stability and fast response.  As with all other Rheonik mass flow meters, this model is based on the patented Omega tube design with increased signal to noise ratio.

The RHM 12 mass flow meter can measure flow rates up to 10 kg/min (21 lb/min) with extremely fast response times and excellent repeatability. A true solution, particulary for application such as batching where fast response times are needed, manufactured by Rheonik, the mass flowmeter experts

This unique design, which offers excellent performance and reliability, has created the most satisfied customers worldwide. Unlike other mass flowmeters,  Rheonik uses a patented torsion swinger with the Omega shape and support bars which results in high accuracy measurement, which is independent of pressure, even at very low flow velocities. The meter has also extremely good repeatability and high stability for critical applications.

Order Code Rheonik Coriolis Mass flow meter RHM12

The maximum pressure (Pmax) of a sensor is determined by its lowest rated part. The lowest rated part can be either the measuring tube (Pmax indicated below), the construction type (Pmax indicated in the Part Number Code section, last page) or the process connection (for Pmax see published standards or manufacturer information).
