Proline Prosonic Flow W 400


Proline Prosonic Flow W 400

Clamp-on flowmeter for the water and wastewater industry and for utilities: flexible, easy to install and safe


Field of application

Prosonic Flow W 400 is the meter of choice for safe, cost-efficient and low-maintenance measurement of conductive and non-conductive liquids. The clamp-on mounting system and integrated web server allow for easy installation and operation. Thanks to the FlowDC option, the specified accuracy can be maintained despite disturbed flow profiles. Heartbeat Technology provides continuous transparency in your process with its diagnostic, verification and monitoring functions.

  • The measuring principle is non-invasive and independent of pressure, density and conductivity

  • Bidirectional flow measurement for water and wastewater as well as process water and hydropower plants

Device properties:

  • Mounting without process interruption

  • Wide nominal diameter range: DN 15 to 4000 (½ to 160")

  • Medium temperature up to +130 °C (+266 °F)

  • Transmitter housing made of durable polycarbonate or aluminium

  • Remote version for wall mounting

  • Integrated data logger: measured values monitoring


  • Short inlet run thanks to FlowDC

  • Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000/160")
