Detects if water flow rate is at desired level. A built-in contact closure switch can remotely turn on/off a chemical pump and/or other external devices when flow rate is within desired range. Additionally, this can be used as an alarm signal if flow rate is not within flow range target, potentially indicating a clogged filter, malfunctioning equipment, closed valve, etc.With flow rate sensor installed at targeted flow rate, the sensor can detect if your flow is within desired range. The alarm window is approx. 10GPM (varies).
ie. Target water flow rate is 65 GPM, alarm is placed so that 65 GPM is positioned in middle of indicator window. Sensor will trigger alarm at flow from 60 to 70 GPM
