Prosonic Flow W 400 – flexible, simple and safe

The clamp-on flowmeter for the water and power plant industry as well as for utilities

Publication date: 17.01.2022

Ultrasonic flow measurement with clamp-on sensors has been used successfully in many industries. But even in basic and standard applications, requirements are growing steadily due to process automation. Prosonic Flow W 400 therefore combines proven ultrasonic measurement technology with the advantages of Endress+Hauser’s Proline device series, thus meeting the requirements of plant operators: cost efficiency, comprehensive process monitoring and maximum freedom when planning measuring points.

Benefits

  • Non-intrusive flow measurement without maintenance. Directly mounted on the exterior wall of the pipe without opening the pipe

  • For the measurement of numerous fluids, e.g. in the fields of water/wastewater, power/energy plants, utilities, etc.

  • Very large nominal diameter range: DN 15 to 4000 (½ to 160")

  • Suitable for pipes made of metal, plastic, GRP or composite materials with or without lining

  • Time-saving on-site operation and simplified installation thanks to the integrated web server (without additional software/hardware)

  • Heartbeat Technology for device verification during operation without process interruption

The clamp-on design enables safe measurement of even corrosive, abrasive and toxic fluids – regardless of conductivity or pressure. That makes Prosonic Flow W 400 ideal for monitoring and controlling numerous processes: quantity and volume measurement, totalizing and balancing, verification of previously installed flowmeters and detection of leaks in a pipeline.

FlowDC function for maximum performance with disturbed flow

Prosonic Flow W 400 can be ordered optionally with the unique FlowDC function that detects and compensates for effects of flow disturbance, e.g. downstream of pipe bends. This makes it possible to maintain a consistent accuracy even with a significant reduction in inlet runs – e.g. from 15 pipe diameters all the way down to 2 pipe diameters. This means maximum flexibility for planners and users, should they want to equip or retrofit a plant with clamp-on flowmeters.

Fits on any pipe

Prosonic Flow W 400 can be mounted on a wide variety of pipelines. A maintenance-free contact foil (coupling pad) provides optimum sound transmission between sensor and pipe. The resulting constant, high signal strength ensures stable measurement results over many years. Depending on the line size, fluid and pipe material, the sensors are delivered with different ultrasonic frequencies (0.3 – 0.5 – 1– 2 – 5 MHz) so that users can fully rely on maximum signal quality, accuracy and repeatability.
