The RIV400 series Variable Area Flowmeter Riels are indicators of local capacity, in stainless steel with transmission of reading through magnetic coupling.They are suitable for low flow of gases and liquids at high pressures and temperatures.

In addition to the basic version, (only visual indicator) these flowmeters are available with electronic microprocessor technology with two wire output signal 4 to 20 mA, intrinsically safe version EExi.

Devoid of seals, they can be equipped with tap, of flow regulator and alarms of minimum and maximum flow.
The connections can be threaded or flanged, axial or angle on request.
