2. DESCRIPTION
The 150mm High /Low Alarm Flow Meter with Optical Sensor Switch is a nonin-
vasive 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.
