Problems solved by technology

For example, if there are other parts inside the pipeline, such as a pipeline with a smaller inner diameter, an annular space is formed between the inner and outer tubes, and the ultrasonic waves propagating between the upstream and downstream sensors may be blocked by the inner tube, and the inner tubes in this space The flow profile is more complicated, etc.

Abstract

The invention discloses an ultrasonic method and device for measuring a fluid flow.The method is used for measuring a flow of a fluid flowing in a space.The method comprises the steps that ultrasonic waves are transmitted and received by penetrating through the space among multiple pairs of ultrasonic sensors along multiple propagation paths respectively, the mean linear velocity of the fluid is calculated based on data obtained by each pair of the ultrasonic sensors so as to obtain multiple linear velocities penetrating through the space, and the flow of the fluid is calculated based on the multiple mean linear velocities.The invention further relates to the ultrasonic device using the method to measure the fluid flow.

Description

technical field [0001] The present invention relates to an ultrasonic method and an ultrasonic device for measuring fluid flow using the method. Background technique [0002] Ultrasonic devices and methods are widely used to measure the physical properties of fluids, such as liquids or gases flowing in pipes. There are many methods for measuring fluid flow with ultrasound, and one of the most widely used methods is the transit-time method. [0003] Such as figure 1 As shown, when the time difference method is used to measure the flow rate of the fluid, a sensor is generally placed on the upstream and downstream of the fluid. By alternately sending and receiving a burst of ultrasonic signals between two sensors, and measuring the time it takes for the signal to travel between the two sensors, the time T required for the signal to travel from the upstream sensor to the downstream sensor can be obtained, respectively. down , and the time T required for the signal to travel f...
