Proteus 200 Series Flow Meters 0-5 VDC or 4-20 mA output Adjustable Relay Trip Point Models Span 0.08 to 60 GPM ( LPM) Visible Indication of Flow LED Display Available 5-year warranty Proteus 200 Series flow sensors provide a 0-5 VDC or 4-20 mA output proportional to flow rate, and an adjustable relay trip point. The analog output may be used to provide feedback to valves or pumps in a closed- loop system or to provide flow rate information to a PLC or other electronic control. The relay trip point may be used to trigger an alarm or shut down equipment if the flow rate falls below a minimum acceptable level. How it Works Fluid flowing through the sensor spins a magnetic rotor to induce a voltage in a coil. An electronic circuit measures the frequency of the electrical pulses generated and computes the flow rate. This rate is converted to a 0-5 VDC or 4-20 mA output proportional to the flow rate. The output voltage is also compared with a user-adjustable trip voltage. When the measured voltage is above the selected trip voltage a relay is held in its active position. If the measured voltage falls below the selected trip point voltage or should the fluid stop flowing, the relay is switched off. The change of state of the relay is used to trigger your interlock or alarm system. The relay trip point may be preset at the factory or adjusted by the user by turning a potentiometer. A red- green LED mounted on the side of the flow meter electronics indicates relay state. Display Flow Rate Flow can be displayed directly in GPM or LPM on a calibrated digital voltmeter. See the 200 Series Price List for ordering details. Flow Visibility
