AI Technical Summary
In large-diameter pipelines, the uneven flow rate of the medium from the center of the pipeline to both sides causes the distribution of the pressure extraction point to affect the detection structure, resulting in errors in the pressure extraction value and the flow cannot be accurately detected.
A Byrons flowmeter was designed, using a semi-hyperbolic structure of positive pressure production port and negative pressure capturing head. The negative pressure capturing head is distributed inside the pipeline to deviate from the flow surface, and the section and the horizontal plane are in a reverse oblique angle. The positive pressure pressing port is located near the inner wall of the pipeline, and the second positive pressure pressing port is located at the axial center. Through this structure, the resonance point is avoided to achieve uniform pressure collection of flow.
Through this structure, uniform pressure collection of flow rates within the pipeline is achieved, resonance frequency is avoided, and flow values are accurately collected, which improves detection accuracy.

[0002] Flowmeter is an instrument that indicates the measured flow rate and the total amount of fluid in a selected time interval. In simple terms, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel. Flowmeters are divided into differential pressure flowmeters, rotor flowmeters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. Classified by medium: liquid flowmeters and gas flowmeters.
[0003] In the process of implementing this invention, the inventors found that there are at least the following problems in this technology: the pressure sampling port of the detection flow meter is distributed at a certain position in the pipeline. When the pipeline diameter is large, the flow velocity of the medium in the pipeline from the center of the pipeline to both sides is different. Therefore, the distribution position of the pressure sampling point affects the final detection structure, resulting in errors in the pressure sampling value and inability to accurately detect.
[0004] To this end, we propose a Byrons flowmeter. Utility Model Content

[0017] (1) The Byrons flowmeter is convenient for collecting the liquid flow at the center of the pipeline by setting the second positive pressure sampling port, and convenient for collecting the liquid flow near the inner wall of the pipeline by setting the first positive pressure sampling port.
