Rheonik RHM02L Corioliss Mass Flow Sensor


Coriolis Rheonik’s flow meter unique design, which offers excellent performance and reliability, has created the most satisfied customers worldwide. Unlike other mass flowmeter manufacturers, Rheonik uses a patented torsion rod 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.

Rheonik RHM02L Corioliss Mass Flow Sensor is a meter designed for general purpose flow measurement without the need for maintenance.  Robust and accurate, the RHM20 outperforms other flow technologies at an attractively low cost of ownership.

* At Qnom, pressure drop across a parallel tube sensor will be approximately 1- 3 bar (15-44psi) forH20. Sensors can be operated at higher flow rates but pressure drop will be higher.Qmin is the recommended lowest flow rate. Sensors will measure flow rates lower than Qmin, but uncertainty will increase beyond 0.5% of rate.

The flow specifications above relate to standard pressure, parallel tube, manifold sensor versions. Models with higher pressure ratings have increased wall thickness and will have higher pressure drops
