Prosonic Flow W 400 is the ultrasonic clamp-on flowmeter of choice for safe, cost-effective and maintenance-free measurement of conductive and non-conductive liquids. It measures flow noninvasively and bidirectionally, independent of pressure, density and conductivity, and without process interruption.

FlowDC makes mounting as flexible as never before. The specified accuracy is maintained at an inlet run of only 2 x DN, even in the case of disturbed flow profiles.

Special coupling pads make this ultrasonic clamp-on system maintenance-free during the entire product life cycle.

Heartbeat Technology provides continuous process transparency with its diagnostic, verification and monitoring functions. This way, build-up can be detected before it affects operation."    "Benefits
Flexible mounting – FlowDC reduces inlet runs to a minimum

Reliable measurement performance – proven sensors in combination with maintenance-free mounting system deliver long-term stable signals

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

User-friendly operation – the web server offers full remote access, while the device’s display offers convenient on-site interaction

Transparent process insights – Heartbeat Technology with its integrated diagnostics, verification and monitoring functions enable compliance and process safety at all times"    "Measuring principle
