The OMEGA® FP7001A paddlewheel flow and temperature sensor is ideal for accurate monitoring of typical industrial water flows, hard-tohandle corrosive aqueous solutions, and high purity fluids (see Wetted Materials for details). The FP7001A utilizes a paddlewheel-like rotor whose motion is converted into a high-level square wave pulse output by an open collector Hall effect sensor. Pulse amplitudes from 5 to 18 V are possible, depending on input power. The FPW-15 120 Vac converter plugs directly into a wall socket and outputs a regulated 15 Vdc at 400 mA.
