Field of application
Prosonic Flow I 400 combines insertion sensor technology with the benefits of our Proline 400 transmitters, such as Heartbeat Technology for safe process monitoring and web server access for easy installation and operation. Welded directly into the pipe wall, Prosonic Flow I 400 is especially suitable for large pipelines such as water distribution lines and projects where a fixed device installation is necessary.
The measuring principle is independent of density and conductivity
Bidirectional flow measurement of water and wastewater
Device properties:
Supports two parallel measurement paths
For large diameters: DN 200 to 4000 (8 to 160")
Medium temperatur: –40 to +80 °C (–40 to +176 °F)
Transmitter housing made of durable polycarbonate or aluminium
Remote version for wall mounting
Integrated data logger: measured values monitoring
Benefits
-
Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000/160")
-
Long-term stable signal – maintenance-free direct installation of the sensor into the medium
-
Process transparency – diagnostic capability
-
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
