| High Light | Doppler Ultrasonic Flowmeter ，Portable Doppler Ultrasonic Flow Meters ，Doppler Type Ultrasonic Flow Meter | ||
Doppler ultrasonic flowmeter is a flow measurement instrument based on the Doppler effect. It calculates the flow velocity and flow rate by detecting the frequency shift of ultrasonic waves reflected by suspended particles or bubbles in the fluid.
| Characteristics | Doppler Ultrasonic Flowmeter | Time Difference Ultrasonic Flowmeter |
|---|---|---|
| Working Principle | Utilizes frequency changes in reflected waves (Doppler effect) | Measures the time difference of sound wave propagation in the forward and reverse directions |
| Measurement Object | Velocity of suspended particles/bubbles in the fluid | Velocity of sound wave propagation in the fluid itself |
| Ideal Medium | Turbid and dirty liquids with an appropriate amount of scatterers (wastewater, slurry) | Clean, single-phase, bubble-free liquids (tap water, solvents, fuel) |
| Requirements for Suspended Matter | Must be present; otherwise, it cannot operate | Must be absent; otherwise, it will interfere with the sound wave |
| Typical Accuracy | ±1% ~ ±5% FS | ±0.5% ~ ±1% FS (can be higher) |
| Cost | Generally relatively low | Generally relatively high |
Doppler ultrasonic flowmeters are a powerful tool for measuring the flow of dirty and solid-containing fluids. With its unique working principle, it has an irreplaceable position in industrial fields such as sewage treatment, mining, and papermaking. When choosing, it is essential to make the right judgment based on the characteristics of the medium.
