System Sensor WFD30N Detector Refrigerant Circuit Protection: Integrated thermal andThe System Sensor WFD30N is a heavy duty vane type waterflow detector engineered specifically for integration into 3 inch schedule 10 through 40 steel piping systems. Designed for wet pipe fire protection and hydronic installations, this flow switch utilizes a durable polyethylene vane and a mechanical pneumatic retard mechanism to minimize false alarms caused by pressure surges or trapped air. With a static pressure rating of 450 PSI and a NEMA 4
