Product Description
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.
- Proficient in measuring dirty media: This is its core advantage. The more suspended solids there are, the stronger the signal.
- Non-contact installation: Clamp-on or insertion type, no need to cut the pipe, no pressure loss.
- Can measure non-full pipe flow: Some models are designed to be installed at the bottom of the channel and can measure non-full pipe flow.
- Simple principle, potentially lower cost: For some applications, Doppler instruments may be more cost-effective.
| 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 |
- The Doppler method is highly suitable for measuring fluids containing a large number of scatterers.
- Fluids with impurities: It is applicable to sewage, mud, ore pulp, circulating water, slurries in chemical processes, and liquids with bubbles, but not to pure water.
- Non-full pipe measurement: It can solve the monitoring problems of non-full pipe fluids in drainage pipes and open channels.
- Typical fields: Municipal drainage, sewage treatment, industrial wastewater, agricultural irrigation, natural river monitoring, etc.
- If the liquid is turbid, opaque, or contains visible suspended matter, the Doppler method is usually a better choice.
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.
