Flowmeter for the continuous measurement of water
The Type 8081 ultrasonic flowmeter is intended for the flow measurement of water which may be slightly charged with contaminants. It consists of an electronic module and a brass fitting with a built-in measuring tube. In combination with a controller and a control valve, it enables very simple flow control loops to be established. The electrical connection is made via a 5 pin M12 fixed connector.
