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

Benefits

  • Short inlet run thanks to FlowDC

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

  • 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

  • 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
