FLOW SENSORS ELECTRONIC Dimensions Flow Set Point Switching RFS Types Polypropylene Bodies Combines visual confirmation of flow with dynamic, electronic switch operation 2.37 (60.2 mm) Easy, adjustable switch point calibration: .64 (16.3 mm) a local LED signals when set point is reached RotorFlow Switches build an extra level of reliability and 2.50 (63.5 mm) 3.06 (77.7 mm) protection into your equipment. By principle of operation, the rotor cannot be deceived into indicating a positive flow situation when no flow actually exists. Once VDC VAC set to a desired actuation point, RotorFlow will switch to a no-flow condition should the rotor stop for any reason.

A small flat-blade screwdriver is LED INDICATOR IS ILLUMINATED WHEN the only tool required. CABLE RELAY SWITCH IS OUTPUT CLOSED. AIDS FIELD 1. Adjust liquid flow in the line to the rate at which switch actuation is desired. CALIBRATION 2. Insert screwdriver into opening on backside of housing and fit blade into the potentiometer adjustment screw inside. 3. If LED is not illuminated, slowly turn screwdriver counterclockwise and stop as SET POINT soon as LED illuminates. ADJUSTMENT 4. If LED is illuminated, turn screwdriver clockwise until LED light goes out. Then, slowly turn screwdriver counterclockwise and stop as soon as LED illuminates.
