Bürkert Type 8081 – 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. 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)
