Explore the Principles of Non-Invasive Flow Measurement
This interactive guide demystifies ultrasonic flow meters. Discover the two core technologies—Transit-Time and Doppler—and learn how to choose the right one for any application, from high-purity water to abrasive slurries.
Core Technology Explorer
Select a technology to see how it works. This section provides an animated visualization of the physical principle, a clear explanation, and a summary of its key advantages and limitations.
At-a-Glance Comparison
This chart provides a direct visual comparison of the two technologies across key performance metrics. Hover over the points on the chart to see how Transit-Time and Doppler meters stack up in terms of accuracy, fluid compatibility, and sensitivity.
Industrial Application Guide
The choice of technology is driven by the application. Explore common industrial sectors below to see which meter type is typically used and understand the rationale behind the selection.
Interactive Technology Selector
Answer two simple questions about your application, and this tool will recommend the most suitable ultrasonic flow meter technology based on the report's selection framework.
"Clean" means single-phase liquids with less than 2% solids/bubbles. "Contaminated" means slurries, wastewater, or aerated liquids.
High accuracy is for custody transfer or critical control. Moderate is for general monitoring.
Advanced Concepts & Future Outlook
For those interested in the cutting edge, this section briefly explores advanced techniques that enhance accuracy and expand the capabilities of ultrasonic measurement.
