Fluidex PWF series is a cost effective Dual Pulse, Paddle Wheel Flow meter designed to measure the flow rate of low viscosity liquids. The PWF series is suitable for installation in pipes with diameters from DN40 to DN2500 (1½"~100"). The metering head is inserted in 1/8th into the pipe resulting in very little pressure drop. The meters do not require external power when used with Fluidex battery powered rate totalizers. The PWF series is widely used in HVAC (hot & chilled water), fire protection and hydrant flow testing, water distribution (management & treatment), boiler feed water & many other applications.
