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:

• 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.
