Rheonik RHM15 Coriolis Mass Flowmeter

The RHM 15 is an all-purpose meter suitable for liquid processing plants. A wide application flow range capability allows for commonality of installation across numerous lines – a real benefit to owners and operators.


With highly accurate measurement performance and extreme capabilities, Rheonik meters are a natural choice for many applications and quickly provide payback through improved product quality and greatly reduced maintenance. Whether used for transfer, batching, process feed or control, Rheonik meters can provide online flow and density measurement.
