Sensor electronics easily removed from tee.
Impeller/bearing/shaft easily replaced in field without changing calibration.
Two wire sensor. Power and signal transmit on single pair of wires up to the distance of 600 m.
Digital signal easily interfaced with transmitters, monitors or PLCs.

The series 250 flow sensor features a six bladed impeller design with aproprietary non-magnetic sensing mechanism. The unique impeller 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 flow rates. This is especially true where the impeller is exposed to metallic or rust particles found in steel or iron pipes.

As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate. The signal can travel up to 600 m between the flow sensor and the receiving unit without the need for amplification.

All sensors except irrigation versions are supplied with 20' of 2-conductor 6 m AWG shielded U.L. type PTLC 105°C cable and meet CE standards for noise immunity and susceptibility
