Product Description
Applicable To Extremely Complex Medium Correlation Method Ultrasonic Flowmeter
Correlation method ultrasonic flowmeter is a type of ultrasonic flowmeter based on the principle of "cross-correlation analysis".
- Unaffected by changes in sound speed: This is its greatest advantage. It measures the transmission time of the "pattern" and does not rely on the absolute sound speed of ultrasonic waves in a stationary fluid. Therefore, it is completely unaffected by changes in sound speed caused by variations in fluid composition, temperature, and pressure, ensuring extremely high and stable accuracy.
- Applicable to extremely complex media: It can measure almost any heterogeneous fluid, including high-concentration slurries, gas-liquid two-phase flows, liquid-solid two-phase flows, non-Newtonian fluids, viscous liquids, etc. As long as there are detectable random disturbances in the fluid.
- Excellent linearity: The flow rate has a strict inverse relationship with the transmission time, resulting in very good measurement linearity.
- No moving parts, non-contact/low-contact.
| Characteristics | Related Method Ultrasonic Flowmeter | Time Difference Method Ultrasonic Flowmeter |
|---|---|---|
| Measurement Object | The transmission time of "randomly marked patterns" in the fluid. | The propagation time difference of the ultrasonic "wave" itself. |
| Dependence on Sound Speed | Completely independent, immune in principle. | Highly dependent, requires precise measurement and compensation for sound speed changes. |
| Applicable Medium | Non-homogeneous, complex multiphase flows (slurries, gas-liquid mixtures, etc.). | Relatively homogeneous, clean single-phase fluids (water, oil, gas). |
| Accuracy Influencing Factors | Primarily affected by the accuracy of the sensor spacing L and signal quality. | Affected by multiple factors such as sound speed changes, flow profile, and installation angle. |
| Cost and Complexity | High. | Moderate (single-channel) to high (multi-channel). |
| Typical Accuracy | Can reach ±0.5% to ±1.0% (under applicable media). | Can reach ±0.5% or even higher in clean fluids. |
| Response Time | Slow (seconds). | Fast (milliseconds to seconds). |
- Mining and metallurgy: Flow measurement of high-concentration ore pulp, tailings pulp, cement slurry, and coal-water mixtures.
- Oil and energy: Measurement of three-phase oil, gas, and water flow, heavy oil, and well production fluids.
- Chemical and papermaking: Pulp, cellulose pulp, polymer solutions, and high-viscosity chemical raw materials.
- Wastewater treatment: Flow control of high-solid-content sludge and digested sludge.
- Research and special industries: Complex fluid dynamics research such as fluidized beds, pneumatic conveying, and food slurries.
Correlation ultrasonic flowmeters are the "specialist experts" and "problem solvers" in the field of flow measurement. They bypass the theoretical bottleneck of traditional ultrasonic flowmeters (speed of sound dependency) and take a unique approach by using the "fingerprint" of the fluid itself for measurement.
