Rain Bird FS150P 1-1/2 in PVC Tee Flow Sensor - FS150P
Rain Bird FS150P 1-1/2 in PVC tee flow sensor provides reliable, commercial-grade flow monitoring for irrigation systems. The sensor's simple six-bladed impeller delivers accurate pulse output to controllers for learned-flow operation, leak detection and centralized monitoring. Designed for outdoor and underground use, the FS150P fits nominal 1-1/2 in (40 mm) PVC piping and is offered in tee and insert styles with NPT or BSP ends.
Installers rely on the FS150P for precise zone flow data that helps detect leaks, verify valve performance and optimize hydraulic sequencing in commercial systems. The sensor's pulse output and wide operating range make it suitable for both stand-alone controllers and central control systems; pair with Rain Bird transmitters or monitor modules where remote display or wiring requires it. Refer to manufacturer literature for model-specific K-factors, wiring diagrams and installation guidance.
