The RIV400 series flow meters are local flow indicators, entirely made of stainless steel with reading transmission through magnetic coupling. They are suitable for low flow rates of high-pressure air or gases, even at high temperatures. They can be equipped with a valve, flow self-regulator, and minimum and maximum flow rate alarms.

In addition to the basic version (visual indicator only), these flow meters are available with two-wire microprocessor-based electronics featuring a 4-20mA output signal, Hart protocol, and Profibus PA interface. Upon request, they can be provided in the intrinsically safe version, certified as ATEX Ex ia IIC T6 for Zone 0 and Zone 1, or with an explosion-proof housing, Exd-rated.
