Ultrasonic flowmeter with rectangular flow channel

Abstract

The invention discloses an ultrasonic flowmeter with a rectangular flow channel. The ultrasonic flowmeter comprises: a body; n upper cover and a lower cover, wherein the upper cover is arranged on the body in a covering mode, the lower cover is arranged at the bottom of the body in a covering mode, and the upper cover is communicated with the interior of the body to form a flowmeter inner cavity;, a gas inlet pipe section connected with the side surface of the body; a flow measuring pipe section connected with the gas inlet pipe section and communicated with the flowmeter inner cavity; a plurality of ultrasonic probes distributed in the flow measuring pipe section; a flowmeter head arranged on the upper cover and in data connection with the multiple ultrasonic probes; and a gas outlet pipe section connected with the side surface of the body. According to the invention, the rectangular flow channel is adopted, airflow is more stable and uniform, and the ultrasonic flowmeter is more suitable for flowmeter measurement; an internal and external separation structure is adopted, so that even if the external part is impacted, the internal flow measuring pipe section is not influenced; a bent vertical structure is adopted, so that the horizontal space is more saved, and the installation applicability is high; and the arrangement of multiple ultrasonic probes is adopted, so that the result is more accurate and mutually redundant.

Description

technical field [0001] The invention relates to the technical field of fluid flowmeters, in particular to an ultrasonic flowmeter with a rectangular flow path. Background technique [0002] In the prior art, the pipe sections of fluids, especially gas flowmeters, are cylindrical, which has become a conventional and commonly known inherent method. Although no standard has been formed, it has been almost standardized. Of course, a circular pipe section of the same length is compared to other shapes. The pipe section has the largest volume and the most stable structure, but for measuring instruments such as gas flowmeters, stable fluid flow is required, especially gas flow, which requires uniform and stable airflow. However, the airflow in the circular pipe section has uneven and unstable flow. Disadvantages, which are fatal flaws for measuring instruments. Contents of the invention [0003] According to an embodiment of the present invention, an ultrasonic flowmeter with a ...
