Problems solved by technology
[0002] At present, in the related technology, the pipeline is connected with the ultrasonic flowmeter. Due to the existence of flow resistance parts such as elbows and valves, the fluid velocity distribution in the pipeline is distorted and the velocity distribution is asymmetrical. Therefore, only the upstream of the ultrasonic flowmeter can be guaranteed. Only with a long enough straight pipe section can the measurement accuracy be met. In general, in field applications, the requirement for a long enough straight pipe section cannot be met, which limits the application range of the ultrasonic flowmeter. Therefore, in order to meet the measurement accuracy of the ultrasonic flowmeter Under the premise of reducing the length of the straight pipe required by the ultrasonic flowmeter, it is very necessary

The invention provides an ultrasonic flow measuring device. The ultrasonic flow measuring device is connected with a pipeline and comprises a rectifier pipe, blades, a mixing pipe, a porous pipe and diversion holes, wherein the rectifier pipe is a hollow circular pipe with two ends opened, and one end of the rectifier pipe is communicated with the pipeline; at least four plate-shaped blades are evenly embedded in the rectifier pipe, and the blades are connected with the inner wall of the rectifier pipe; the mixing pipe is a hollow circular pipe with two ends opened, and one end of the mixing pipe is communicated with the other end of the rectifier pipe; the porous pipe is a hollow circular pipe with one end opened, and one end of the porous pipe is communicated with the other end of the mixing pipe; and at least two diversion holes are arranged on the porous pipe. By adopting the structure, the structure is simple, and by embedding at least four blades into the rectifier pipe, when thefluid flows into the rectifier pipe and the uneven flow flows through the blades, a flow field is redistributed to eliminate secondary flow, eddy flow and the like.
Description
technical field [0001] The invention relates to the technical field of ultrasonic flow measurement, in particular to an ultrasonic flow measurement device. Background technique [0002] At present, in the related technology, the pipeline is connected with the ultrasonic flowmeter. Due to the existence of flow resistance parts such as elbows and valves, the fluid velocity distribution in the pipeline is distorted and the velocity distribution is asymmetrical. Therefore, only the upstream of the ultrasonic flowmeter can be guaranteed. Only with a long enough straight pipe section can the measurement accuracy be met. In general, in field applications, the requirement for a long enough straight pipe section cannot be met, which limits the application range of the ultrasonic flowmeter. Therefore, in order to meet the measurement accuracy of the ultrasonic flowmeter Under the premise of this, it is very necessary to shorten the length of the straight pipe required by the ultrasoni...
