Time Difference Non Contact Ultrasonic Flow Meter For Fluid Flow Efficient Measurement
Time-Difference Ultrasonic Flowmeter For Efficient Measurement Of Fluid Flow
The time difference method ultrasonic flowmeter is a high-precision non-contact measuring instrument that calculates flow velocity and flow rate by utilizing the time difference of ultrasonic waves traveling in the fluid in the downstream and upstream directions.
- High Precision: It is the most accurate ultrasonic flowmeter, with an accuracy of ±0.5% or even higher, suitable for trade settlement.
- Wide Range Ratio: It has a wide measurement range, typically over 1:100, capable of meeting the measurement requirements of both low and high flow rates simultaneously.
- No Pressure Loss: No components are inserted into the flow channel, thus not impeding the fluid flow at all and saving pumping energy.
- Multi-functional: It can measure forward and reverse flow, instantaneous and cumulative flow, and provide diagnostic information such as sound velocity and signal quality.
- Broad Medium Compatibility: It is suitable for measuring clean, single-phase, homogeneous liquids, such as tap water, pure water, fuel oil, solvents, chemical reagents, etc.
There are mainly three installation methods for the time difference method:
| Installation method | Principle | Advantages | Disadvantages | Scenarios |
|---|---|---|---|---|
| External clamp type | The probe is fixed to the outer wall of the pipe with coupling agent. | Non-stop installation, no pressure loss, easy maintenance. | Highly affected by pipe material and condition, extremely high installation requirements. | Temporary detection, energy audits, processes where shutdown is difficult. |
| Insertion type | A hole is drilled in the pipe and the probe is directly inserted into the fluid. | High accuracy, good stability, not affected by pipe wall. | Requires shutdown for installation, slight pressure loss, contact with medium. | Permanent installation, large-diameter pipes with high accuracy requirements. |
| Pipe section type | The probe is pre-installed on a standard short pipe to form an integrated unit. | Highest accuracy, precisely calibrated before leaving the factory, simple installation. |
- Clean fluid: Mainly suitable for clean water, pure water, oil, chemical solvents and other liquids without suspended particles or bubbles.
- High precision requirements: Widely used in water supply companies, industrial circulating water, food and beverage, pharmaceutical and other fields with high measurement accuracy requirements.
- Extreme working conditions: Some models can withstand high temperatures (-200℃ to 200℃), high pressure and strong corrosive media (such as concentrated sulfuric acid).
- Municipal water supply: Pipeline flow monitoring, leakage detection.
- Industrial fields: Petrochemical (LNG transportation), semiconductor ultra-pure water, food and beverage filling, etc.
- Open channel flow measurement: Large channel flow monitoring, supporting solar power supply and remote data transmission.
Summary: The time difference method ultrasonic flowmeter is a high-end solution for clean liquid flow measurement. Its successful application highly depends on "correct selection + professional installation + accurate parameters". Under the premise of meeting its working conditions, it can provide unparalleled long-term measurement performance and reliability.
