The Data Industrial flow sensor features a six bladed impeller design with a proprietary, non magnetic sensing mechanism. The forward swept impeller shape provides higher, more constant torque than four bladed impeller designs and is less prone to be fouled by water borne debris. The forward curved shape coupled with the absence of magnetic drag provides improved operation and repeatability even at lower rates. This is more important where the impeller may exposed to metallic or rust particles found in steel or iron pipes. As liquid flow turns the impeller, a low impedance 8VDC square wave signal is transmitted with a frequency proportional to the flow rate. This signal can travel up to 2000' between the sensor and the display unit without the need for amplification. All the sensors are supplied with 20' of Belden type 9320 (two conductor shield) cable. 228PV and 228PD Flow Sensors
