Gravity Mass Flow meter Rheonik RHM-12


Rheonik Coriolis Mass Flow Meter

Gravity Mass Flow meter Rheonik 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.

Gravity Mass Flow meter Rheonik 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.

Coriolis Mass Flow Transmitter

Inside the measuring sensor, there are precision tubes that are energized by an electromagnetic drive system, which itself is fed by the transmitter, to vibrate at their natural frequencies. When a liquid or gas flows through the vibrating tubes, it is subjected to additional deflection due to the degree of inertia that is generated. This deflection is recorded electronically by two velocity sensors and a high-precision electronic time delta. This measured quantity is proportional to the mass flow rate.

A further conversion into physical units is done in a purely digital manner using a signal processor in the transmitter. At the same time, all of the appliance’s functions are constantly monitored. Should any disruptions occur, all of the errors that have occurred are immediately reported in the display.

This significantly reduces the costs of spare parts for the installed flow sensor/transmitter. During the factory calibration, the mass flow sensor can be calibrated independently of the transmitter. All sensor-specific calibration data can be programmed using magnetic switches located on the front panel. To achieve this, the instrument does not need to be opened. All of the relevant data is buffered in a non-volatile semiconductor device (EEPROM).

d3e7e-coriolis2bmass2bflow2btransmitter

The transmitter has a 4 to 20 mA analogue output with programmable span, which is proportional either to the measured mass flow rate or the temperature; it also has an impulse output that supplies mass-proportional impulses. All of the outputs and measuring functions can be verified at any time by the user by using the diagnostic mode in the appliance. The maintenance or new calibration intervals can be monitored via a run-time counter. For service or repair purposes, the transmitter and flow sensor can be replaced independently of each other.

The RHEONIK mass flow meter consists of one of the RHM series flow sensors and one RHE series transmitter. The remote unit RHE 07/08 is for installation in a safe non-Ex area and is connected to the sensor via a single multi-conductor cable.

Please note, that the types RHE 07/08 and all sensor articles are available in non Ex-versions (without Exnameplate). The RHE 11 (Ex d) may be installed and operated in hazardous Ex-areas (Zone 1 or 2). Ex-series sensors RHM (with Ex-Label) are, when connected with an Ex- Transmitter, made for installation inside hazardous areas (Ex-zone 0, 1 or 2). The transmitter RHE includes seven printed boards which can be replaced during servicing. The remote electronic unit consists of two bent measuring loops in the shape of an omega.
