Proline Prosonic Flow I 400 / 9I4B Ultrasonic Flowmeter

The Proline Prosonic Flow I 400 is a high-performance insertion meter designed for bidirectional flow measurement in water and wastewater applications. Featuring Heartbeat Technology and a web server for remote access, this flowmeter ensures long-term stability with maintenance-free installation. Suitable for large pipes (DN 200 to 4000), it operates within a medium temperature range of -40 to 80 °C (-40 to 176 °F) and delivers accuracy of ±2% for volume flow. With robust construction and integrated diagnostics, this flowmeter is an ideal choice for effective monitoring and management in the water industry.
