Proline Prosonic Flow W 400 ultrasonic flowmeter

Ultrasonic flow

Clamp-on meter with Heartbeat Technology and web server for the water and wastewater industry.
Short inlet run thanks to FlowDC.
Bidirectional measurement for water and wastewater as well as process water and hydropower plants.

Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000/156"). Long-term stable signal – maintenance-free permanent mounting from outside with coupling pads. Reliable measurement on various pipe materials – sensor for GRP and plastic pipes available.
Mounting without process interruption. Wide nominal diameter range: DN 15 to 4000 (½ to 160"). Medium temperature up to +130 °C (+266 °F).

Safe operation – no need to open the device due to display with touch control, background lighting. Full remote access – web server. Integrated diagnostics, verification and monitoring – Heartbeat Technology.
Transmitter housing made of durable polycarbonate or aluminium. Remote version for wall mounting. Integrated data logger: measured values monitoring.
