RN3 Turbine Flowmeter

The RN3 Axial Turbine flowmeter offers a proven, simple and robust solution to testing, measuring, monitoring and dispensing low viscosity liquids such as Alcohol & solvents (Ethanol, Methanol & Spirit Alcohols), water & chemicals and Diesel & light Hydraulic Oils (up to 32 cSt). The body is machined from one piece of 316 Stainless Steel and features Tungsten bearings for improved wear life and an option for a Ferralium (Duplex) rotor for Seawater applications.

The non-contacting inductive pick-up system allows the meter to be used in safe area, Intrinsically Safe EEx ia (ATEX & IECEx) and Flame (Explosion) Proof EEx d (ATEX) applications. Accessories included, amplified pulsed output to give a strong robust square-wave signal, loop powered 4-20 mA output and a range of directly mounted battery powered displays with a variety of outputs.

High pressure versions are available for 5,000 PSI (345 Bar), 10,000 PSI (690 Bar), 15,000 PSI (1034 Bar) & 20,000 PSI (1380 Bar) duty (see RN3 High Pressure)
