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. The flowmeter features, depending on the version: - a pulse output or - a pulse output and a 4…20 mA current output. Each version is available for 5 different flow ranges: - model QN 0.6 DN15: 0.06 to 20 l/min (nominal flow rate 0.6 m3/h namely 10 l/min) - model QN 1.5 DN15: 0.1 to 50 l/min (nominal flow rate 1.5 m3/h namely 25 l/min) - model QN 2.5 DN20: 0.16 to 82 l/min (nominal flow rate 2.5 m3/h namely 41 l/min) - model QN 3.5 DN25: 0.6 to 116 l/min (nominal flow rate 3.5 m3/h namely 58 l/min) - model QN 6.0 DN25: 1 to 200 l/min (nominal flow rate 6.0 m3/h namely 100 l/min)
