Proline Prosonic Flow 90/93

Ultrasonic Flowmeters

Flow measurement for drinking water, wastewater and process water. Ideal for retrofitting without process interruption.

Bidirectional measurement of pure or slightly contaminated liquids. Available as clamp-on (DN 15–4000), insertion (DN 200–4000), or inline (DN 300–2000) versions.

• Clamp-on: non-invasive, easy low-cost mounting from outside the pipe
