Gravity Mass Flow meter Rheonik RHM-12

Rheonik Coriolis Mass Flow Meter




The RHM 12 is an economical meter which has been in production for over 15 years. This meter has been

optimized for applications which require extreme stability and fast response. As with all other Rheonik meters, this model is based on the patented Omega tube design with increased signal to noise ratio.


The RHM 12 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.

PERFORMANCE RHM 03
Max Flow 5 kg/min (11 lb/min)

1. Standart Model



2. Optimized Low Flow Models* / optimized to be operated between 0.015 x Q max and 0.3 x Qmax



3.  Gold Line Models/ application fine tuned meters

Repeatability : better ± 0.05 % of rate
Temperature : better ± 1°C




For serial (single pipe/path) sanitary design Qmax is 2.5 kg/min (50%). Data above refer to standard wall thickness. 
Error of reading (including zero drift) indications refer to reference conditions H2O, 18-24°C (66-76°F), 1-3 bar (15-45 psi).
RHM sensor do not suffer from pressure effect due to torsional oscillation and semi circle (non-deforming) measurement section.
Temperature changes of +/- 25°C around the operating point are negligible.
Pressure drop refers to Newton liquids, with parallel measuring loops and block/manifold connection.
Nominal flow refers to approx. 10 m/s (33 ft/sec) velocity in measuring loops for best performance. 
Calibration to customer range, with increased accuracy, possible.
