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
