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.

Main Features

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.

Installation methods

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.

Measurement medium

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).

Typical Applications

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.
