Proline Prosonic Flow I 400 Ultrasonic Flowmeter
Brand: Endress+HauserProline Prosonic Flow I 400 Ultrasonic Flowmeter
Brand: Endress+Hauser

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
