Ultrasonic Flow Transmitter Type 8081 is designed for water monitoring applications where the flow has to be monitored with a high dynamic range, high accuracy, and where a lack of moving parts is mandatory. Intended for the measurement of water flows which may be slightly charged with contaminants, the transmitter consists of an electronic module and a brass fitting with a built-in measuring tube enabling a control loop to be established. The electrical connection is made via a 5-pin M12 fixed connector and can feature a pulse output or pulse output coupled with a 4-20 mA current output.
