Founded in 1986, Rheonik manufactures the widest range of coriolis meters on the market with high pressure designs above 20,000 PSI. Rheonik’s unique omega tube design solves the most challenging process applications in mass flow metering. The range of flows, pressures, available materials, and customizable process connections make them ideally suited to serve the demanding requirements of refineries, pipelines, chemical plants and offshore facilities.



The RHM series coriolis meters by Rheonik surpass other technologies in customization options, range and capability. From low to high flow, low to high pressures, standard to exotic materials and all types of process connections, these meters can be engineered to specification, reliably measuring benign to highly corrosive mediums with ease.
