Abstract

The invention discloses an acoustic wave matrix-based liquid flow measurement device and method and belongs to the technical field of flow measurement. The acoustic wave matrix-based liquid flow measurement device comprises a rectangular water measurement tank internally in a hollow structure allowing fluid to flow through, and two groups of ultrasonic probes arranged on two opposite side surfacesinside the water measurement tank; the two groups of ultrasonic probes are in matrix arrangement and one-to-one correspondence, the connecting line between two corresponding ultrasonic probes forms an included angle to the flowing direction of fluid; the ultrasonic probes are connected with a measuring unit inside a control box. By performing flow measurement through the acoustic wave matrix produced by the ultrasonic probes, the acoustic wave matrix-based liquid flow measurement device can be applied to measuring different positions and different velocities at the same height to accurately reflect the overall velocity of the fluid and further to achieve the aim of accurate measurement. Besides, the acoustic wave matrix-based liquid flow measurement device is simple in structure, practical, convenient, and accurate in measurement.

Description

technical field

[0001] The invention relates to a liquid flow measurement device and a measurement method based on an acoustic wave matrix, belonging to the technical field of flow measurement. Background technique

[0002] Before the 1980s, almost all hydrological stations at home and abroad used the velocity-area method based on the rotor-type current meter to observe the average velocity of the river section layout points and calculate the discharge. Due to its characteristics of accuracy, stability, simple structure and easy mastering, this classic contact flow measuring instrument is still the main tool for river flow detection in our country. However, due to the complex turbulence characteristics of natural rivers, it is difficult to obtain by point measurement technology, or the cost is high, and the harsh field environment also greatly increases the difficulty of hydrological detection. For a long time, not only the river flow velocity, Water flow information such a...
