The 150 mm 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 (alarm, valve, etc. not included). The FLSW Series helps protect your processes and equipment from damage caused by extreme flow rates. Its compact design and ease of operation make it a unobtrusive, simple-to-use addition to your flow meter. This meter is perfect for OEM applications. Use whenever maximum or minimum flow levels need to be monitored automatically. The FLSW Series also can be used in conjunction with a control relay to power alternate equipment or monitoring devices. Principle of Operation 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 setpoint of the sensor. It can also be set to monitor float position at a specific level, signalling when float is outside of the range of the sensor light beam. DIP Switches are located next the the 9-pin D connector. In order to activate the alarm sensors the corresponding switch has to be in the “ON” position on the DIP switch. The relay output or the buzzer or the green LED can be separately set for momentary or latch operation. If for example DIP Switch SW1 is set to “ON”, when the left sensor is active, the relay and the green LED will be energized in the latch mode. It will remain latched until the RESET button is pressed or external RESET TTL signal is applied.

What are the incremental units of measurement on the FLSW3410ST-A model? I know the max flow for this model is 16737 ml/min.

Thank you for your inquiry about the rotameter with alarms. The flow tube is a 150 mm where a correlation chart is included to provide the volumetric flow for that flow meter. You may send an email to request for a correlation for that specific rotameter at firstname.lastname@example.org
