Dynasonics® Ultrasonic meters measure flow rate by propagating ultrasound waves into liquid-filled pipes and measuring the reflections. With either transit time or Doppler technology, these clamp-on ultrasonics meters reside outside the pipe, providing flexibility across a wide range of pipe sizes, no pressure head loss, no contact with internal liquid and no moving parts to maintain.

Increase Measurement Accuracy. Reduce Installation Costs.

Ultrasonic flow meters are a popular solution to simplify flow measurement across a variety of applications. 

  • Impressive Accuracy. Maintain accuracy across a wide range of applications with a greater extended low flow accuracy compared to mechanical meters.

  • Flexible Installation. Can be installed permanently or temporarily—clamp-on meters can be installed by a single user within an hour as a temporary measurement solution or to verify the accuracy of other meters.

  • Minimal Maintenance. Feature a streamlined design without moving parts, which results in minimal maintenance and low cost of installation and ownership.

Measuring Principle

Ultrasonic meters measure the velocity of a fluid flowing through a pipe in one of two ways: transit time or Doppler technology. Transit time technology measures the time differential between signals sent upstream and downstream. The differential is directly proportional to the velocity of the water. Doppler technology measures the difference in sound wave frequency reflected off gas bubbles or particles in the flow stream.

How it works

Dynasonics® TFX-5000 Ultrasonic clamp-on flow meter is quickly and easily installed without cutting or tapping the pipe. This highly capable meter provides advanced features without breaking your budget.

Simple Clamp-on Design. Streamlined Installation.

The Dynasonics TFX-5000 Ultrasonic clamp-on flow meter reduces installation time and cost because operations can continue during installation, which can be completed in under an hour by a single person.

  • Non-Invasive/Non-Contact. These meters easily attach to a pipe’s exterior and are secured in place without ever penetrating the pipe or coming in contact with the internal liquid. This feature is especially beneficial in settings where the liquid should not be exposed, such as caustic liquids, raw sewage or ultrapure water. 

  • Flexible Configuration. Available in a variety of configurations, allowing you to select the meter that’s best for your specific application.

  • Minimal Maintenance. Has no moving parts, which virtually eliminates the need for maintenance or part replacement over the meter’s lifetime. 

Dynasonics® DFX Doppler Ultrasonic flow meter measures the flow of aerated liquids or those containing suspended particles that reflect ultrasonic energy.

Increase Read Accuracy. Reduce Downtime.

The Dynasonics DFX Ultrasonic Doppler flow meter features a clamp-on design that streamlines installation and eliminates the worries of fluid compatibility and pressure head loss.

  • Streamline Installation. Because of its clamp-on design, the DFX Ultrasonic Doppler flow meter can be installed while operations run—there is no need to shut processes down or drain pipes.

  • Application Flexibility. Measures liquids containing suspended particles or aerated liquids, making it suitable for applications with sewage and mud slurries.

  • Simple Design. Does not have moving parts, which greatly reduces maintenance needs because there is nothing that will wear down over time.
