Zurn Industries LLC Flow Sensor ZF7000

The ZF7000 Sensor is designed to notify the building maintenance staff whenever there is flow in the overflow drainage system, typically an indication of either a primary drainage system blockage or the inability of the primary system to adequately handle the water load on the roof. The multiple sensor positions of the in-pipe pickups provide alerts for both low and high flow conditions. Any registered flow level remains present until manually cleared, ensuring that the drainage system is not only monitored around the clock, but that no one needs to be present to witness the event. The information provided by the ZF7000 Sensor alerts the owner to the maintenance needs of the drainage system, possibly avoiding a catastrophic structural failure. The flow sensor pick-up is supplied in a 6-inch-long section of pipe to be installed by either no-hub gaskets or gluing the PVC section into a horizontal run of the overflow drainage line. The signal is sent to the control unit via a low voltage 12V signal (wiring not included). Power is supplied to the unit from a 120 volt to 12 volt plug in transformer, included with the sensor. There is also an option for a battery back up to power the unit in case of a power failure.
