RIV400G air and gas flow meters
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.
