The Proline Prosonic Flow W 400 Ultrasonic Clamp-On Flowmeter provides accurate non-invasive flow measurement for water and wastewater applications. It uses ultrasonic transit-time technology, allowing measurement without direct contact with the medium.

Because of its clamp-on design, installation is quick and does not require pipe cutting or process shutdown. In addition, the device delivers reliable performance for large pipelines, retrofits, and temporary measurements. This makes it ideal for municipal water systems and industrial applications.

Not Recommended For:
• Liquids with very high gas content or heavy solids
• Applications requiring inline measurement with maximum accuracy

Selection Notes

• Measurement Principle: Uses ultrasonic transit-time technology. It is suitable for clean or slightly contaminated liquids.

• Installation Type: Features a clamp-on design, mounted outside the pipe. No pipe modification is required.

• Application Type: Ideal for water supply, wastewater, and large pipeline monitoring.

• Pipe Conditions: Ensure proper pipe material, diameter, and surface condition for accurate signal transmission.

• Output and Communication: Supports 4–20 mA, pulse, HART, and digital communication options.

Why Choose the Prosonic Flow W 400

• Non-Invasive Measurement
The clamp-on sensors are installed outside the pipe. Therefore, there is no contact with the medium and no risk of leakage or contamination.

• No Pressure Loss
Since there is no intrusion into the pipe, the flowmeter does not create pressure drop. This improves system efficiency.

• Fast and Flexible Installation
Installation requires no pipe cutting or shutdown. As a result, it is ideal for retrofits and temporary flow measurement tasks.

• Reliable Ultrasonic Technology
The device uses transit-time measurement, providing stable results for water and similar liquids.

• Perfect for Large Pipes
It performs well in large-diameter pipelines, where inline flowmeters may be difficult or costly to install.

FAQ

Q: What is the main advantage of a clamp-on flowmeter?
A: It allows non-invasive installation, meaning no pipe cutting, no process interruption, and no risk of leakage.

Q: What types of liquids can it measure?
A: It is best suited for water and similar liquids with low gas or solid content.

Q: Does it affect pipeline pressure?
A: No. Since it is installed externally, it creates no pressure loss.

Q: Is it suitable for permanent installation?
A: Yes. It can be used for both temporary and permanent flow monitoring, depending on application needs.
