Working Principle

A+X Ultrasonic flow meters calculate fluid flow velocity by measuring the propagation time of ultrasonic waves in the medium. The difference in transmission time between upstream and downstream sensors reflects the flow velocity, which is then converted into flow rate.

During measurement, the sensors located upstream and downstream simultaneously emit ultrasonic pulses, one propagating against the flow and one propagating with the flow. The pulse propagates faster in the direction of the flow than against it. Since the two pulses travel the same distance, the time difference in transmission directly reflects the flow velocity of the fluid. The greater the time difference between these two ultrasonic pulses, the greater the flow rate.

●  Wide Turndown Ratio: Accuracy maintained over a 200:1 range, suitable for industries like petroleum, chemical, metallurgy, power, hospitals, and schools where flow variations are significant.

●  Non-contact Measurement: Measures flow via ultrasonic wave propagation time without direct fluid contact, adaptable to diverse environments.

●  Zero Pressure Loss: No interference with the flow field, ensuring no additional resistance or pressure loss—ideal for high-precision applications.

●  High Accuracy & Reliability: Excellent for corrosive, non-conductive, radioactive, or flammable media.

●  Wide application range: It can measure the volumetric flow rate of liquids and gases, applicable to pipelines of various diameters, including large-diameter pipes.

●  Zero-point stability: Can detect very small flow rates, useful for detecting pipeline leaks and early warning.

●  Easy Installation & Maintenance: No pipe cutting required; no valves, flanges, or bypass pipes needed.

●  Fluid Property Independence: Unaffected by pressure, temperature, viscosity, or density; suitable for contaminated or corrosive media.

Applications
