Inline Ultrasonic Flow Meter Working Principle

Inline Ultrasonic Flow Meter is a meter that measures the flow of liquid in a round tube based on the principle of ” transit Time”. It adopts advanced multi-pulse technology, signal digital processing technology, and error correction technology. The flow meter can be more adapted to the environment of the industrial site, and the measurement is more convenient, economical, and accurate. The products have reached the advanced level at home and abroad and can be widely used in petroleum, chemical, metallurgy, electric power, water supply, and drainage fields.

Ultrasonic flowmeters are the same as electromagnetic flowmeters. Because the flow channel of the instrument is not equipped with any obstructions, it is an unobstructed flowmeter. It is a type of flowmeter suitable for solving difficult problems in flow measurement. Especially in large-diameter flow measurement. The advantages. It is one of the rapidly developing types of flow meters.

Transit Time Ultrasonic Flow Meter adopts the measurement principle of the time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.

The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.

By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

Notes:
V measure fluid velocity
M ultrasonic reflection times
D pipe diameter
θ The angle between the ultrasonic signal and the fluid
T up The time when the downstream sensor transmits the signal to the upstream
T down Time from upstream sensor to downstream
ΔT = T up – T down

Pipe section In-line sensors

Pipe section In-line sensors

Pipe section sensor: The pipe section sensor is a measurement method in which the pipe section sensor is directly connected to the pipeline under test by using a flange or thread. This sensor solves the problem of man-made or measured pipelines during the installation of the external clamps and plug-in sensors. Errors caused by inaccurate parameters. It has the characteristics of high measurement accuracy, good stability, and maintenance-free.

Clamp-on ultrasonic flow meter

Clamp on Ultrasonic Flow Meter ( Model: 3000S) is composed of a host and an external clamp sensor. The flow measurement of various liquids can be completed by simply sticking the external clamp sensor on the surface of the pipeline. Compared with the traditional flowmeter, it does not need to cut off the pipe and flow, the installation is convenient and quick, and it truly realizes the lossless installation. Compared with the common TDC algorithm of other manufacturers, TGA measurement technology is an algorithm for measuring process time with higher speed and higher accuracy.
