2. DESCRIPTION

The 150mm High /Low Alarm Flow Meter with Optical Sensor
Switch is a noninvasive means for detection of a HI or LOW flow.
This sensor is ideal for signaling an alarm, cutoff valve, or other
device when the float passes the detector. A small LED sensor and
receiver are mounted on one side of the flow meter. The float inside
the flow tube is detected as it passes across the beam of light.
Sensor can be used to detect float passage beyond the set point of
the sensor, or also can be set to monitor float position at a specific
level, signaling when float is outside of the range of the sensor light
beam. Device can be configured to activate relay and/or audible
buzzer alarm.
