The DFT compact paddle-wheel flow sensors embodies the same rugged reliability of the workhorse DF in a compact, more economical design. The flow sensor uses an inlet nozzle to re-direct flow onto the paddle, thus there are no straight piping requirements as with many other paddle designs. It is available in two material combinations to handle a wide variety of liquids. The metal, nickel-plated brass version handles water, light chemicals and low-viscosity liquids (<10 cSt), while the plastic PTFE version will stand up to aggressive chemicals. An open collector frequency output is standard with optional analog and controller outputs, which offer LCD displays, analog flow transmitters, programmable relays and totalizer and batch controller options.
