Clamp-On Ultrasonic Flowmeters : Non-Intrusive Flow Measurement for Permanent Installations

The Benefits of Clamp-On Ultrasonic Flow Measurement

• Non-Intrusive : Sensors are clamped onto the outside of the pipe, meaning:
  • No pipe cutting or welding required.
  • No process interruption during installation or maintenance.
  • No pressure drop.
  • No risk of leaks.
  • Suitable for corrosive or high-purity liquids.
• Versatile : Can be used on a wide range of pipe sizes and materials (metal, plastic, etc.).
• Easy Installation : Relatively simple and quick installation compared to inline flowmeters.
• Cost-Effective : Lower installation costs and reduced maintenance compared to traditional flowmeters.
• Wide Rangeability : Can accurately measure flow over a wide range of flow rates.
• Bi-Directional Flow Measurement : Many models can measure flow in both directions

How Clamp-On Ultrasonic Flowmeters Work ?

Transit-Time Method : Two transducers are clamped onto the outside of the pipe. They act as both transmitters and receivers of ultrasonic pulses. The pulses travel through the pipe wall and the liquid. The difference in the time it takes for the pulses to travel upstream versus downstream is directly proportional to the flow velocity.

Applications

• Water and Wastewater : Measuring flow in water distribution networks, treatment plants, and sewage systems.
• HVAC/R : Monitoring flow in chilled water, hot water, and condenser water systems.
• Chemical Processing : Measuring flow of various chemicals without contacting the fluid.
• Food and Beverage : Measuring flow of liquids in sanitary applications.
• Oil and Gas : Measuring flow in pipelines and process systems (with appropriate safety certifications).
• Power Generation : Monitoring flow in cooling water and other systems.
• Building Management : Monitoring water flow for energy management and leak detection.

Key Considerations

• Pipe Material and Size : Ensure the flowmeter is compatible with your pipe.
• Liquid Compatibility : Check compatibility with the liquid being measured.
• Straight Pipe Run : Adequate straight pipe runs upstream and downstream of the sensors are typically required for accurate measurement.
• Accuracy Requirements : Consider the required accuracy level for your application.
• Environmental Conditions : Temperature, vibration, and external interference can affect performance.
