Proline Prosonic Flow I 400

Summary

Product identification

• Product line: Proline Prosonic Flow I 400 ultrasonic flowmeter
• Type: Insertion flowmeter with Heartbeat Technology and web server for the water and wastewater industry.
• Model: Proline Prosonic Flow I 400 / 9I4B

Field of application

Insertion sensor technology combined with Proline 400 transmitters. Suitable for large pipelines such as water distribution lines and projects where a fixed device installation is necessary. Bidirectional flow measurement of water and wastewater. Supports two parallel measurement paths.

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 and background lighting.
• Full remote access – web server.
• Integrated diagnostics, verification and monitoring – Heartbeat Technology.

Operating limits

• Medium temperature range: –40 to +80 °C (–40 to +176 °F)
• Ambient temperature range: -20 to 60°C (-4 to 140°F)
• Max. process pressure: N/A

Feed water

• Measured variables: Volume flow, Flow velocity, Sound velocity
• Measuring principle: Ultrasonic flow
• Nominal diameter range: DN200 to 4000 (8 to 160")
• Measuring range: 0 to 15 m/s (0 to 50 ft/s)
• Max. measurement error (Volume flow): ±2% o.r. above DN200
