GENERAL DESCRIPTION
The Optical Sensor Switch is a non-invasive 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 (alarm, valve, etc. are not included). The Optical Sen-
sor Switch helps protect processes and equipment from damage caused by ex-
treme flow rates.
Its compact design and ease of operation make it a non-obtrusive, simple to use
addition to your flow meter. Perfect for OEM applications, use whenever maxi-
mum or minimum flow levels need to be monitored automatically. It also can be
used in conjunction with a control relay to power alternate equipment or monitoring
devices.
PRINCIPLE OF OPERATION
A self-contained miniature photoelectric sensor (Thrubeam type) consisting of a
transmitter and receiver are mounted at opposite sides of the flow tube on a solid
carrier. The float inside the flow tube is detected as it passes across the beam of
light.The sensor can be used to detect the float passage beyond the setpoint of the
sensor and can also be set to monitor the float position at a specific level, signaling
when the float is outside of the range of the sensor light beam.
TO ORDER A FLOW METER WITH OPTICAL SENSOR SWITCHES
NOTE: Used in conjunction with P, S and T Style Flow Meters.
NOTE: To order a flow meter with a single Optical Sensor Switch add
“O1-” to P, S, or T Model Numbers. Example: O1-P11A4-BA0-032-41-ST-VN.
