Flow meter HDO 250 Alu/PPS Ex
Oval gear flow meter
Description
up to max. 1,000 mPas, with threaded connection Suitable for measuring easily flammable liquids. Liquid examples: For combustible mineral oils, easy flammable hydrocarbons and other chemicals in potentially explosive surroundings. Features: For high flow rates, temperatures and pressures Measurement according to the oval gear principle For thin-bodied up to highly viscous liquids Low friction resistance High accuracy Touch screen display with self-explanatory, multilingual user interface Range of measurement from 1.5 GPM - 45 GPM (6 l/min - 170 l/min) In aluminium (Alu) Benefits: Simple, modular construction Easy handling Precise measuring results at high repeatability No recalibration required for large ranges Low pressure losses in the plant Comprehensive monitoring and safety functions Relay module for preselection is retrofittable at any time Explosion Protection: explosion-proof Delivery rates: Flow volumes up to 170 l/min
