The E+H Proline Prosonic Flow W 400 ultrasonic flow meter is a clamp-on meter providing bidirectional measurement for water and wastewater as well as process water and hydropower plants. The measuring principle is non-invasive and independent of pressure, density, and conductivity. Heartbeat technology provides continuous transparency in processes with its diagnostic, verification, and monitoring functions. With the FlowDC option, the specified accuracy can be maintained despite disturbed flow profiles. The W 400 features a short inlet run, long-term stable signal, maintenance-free permanent mounting from outside with coupling pads, and full remote access via the web server.
