Embedded ultrasonic flowmeter

Abstract

The invention relates to an embedded ultrasonic flowmeter which comprises a metering pipe, wherein metering holes are formed in two sides of the metering pipe in a staggering manner along the axis line of a pipe body; an energy conversion metering assembly is arranged outside each metering hole and comprises a fixing seat connected with the metering pipe; a rotating pipe is mounted in the fixing seat; the outer wall of the rotating pipe is in sliding fit with the inner wall of the fixing seat; reflecting holes corresponding to the metering holes in the metering pipe are formed in the side wall of the rotating pipe; reflectors corresponding to the reflecting holes are arranged in the rotating pipe; an energy converter opposite to the reflectors is arranged at the upper part of the inside of the rotating pipe; and pressure wires are arranged in the rotating pipe above the energy converter. The rotating pipe which is in sliding fit with the fixing seat is arranged, so that water in the metering pipe cannot spurt out under the control of the rotation of the rotating pipe. Thus, the energy converter and the reflectors are convenient to clean or replace. As a result, the precision of the ultrasonic flowmeter is improved and the service life of the ultrasonic flowmeter is prolonged.

Description

technical field [0001] The invention relates to an instrument for measuring heat absorbed or released by using cold water or hot water as a carrier in a heat exchange loop, in particular to an embedded ultrasonic flowmeter. Background technique [0002] Due to the current domestic transducer technology is not mature enough, coupled with the problems of poor water quality, many impurities, and vacant pipeline systems when the pipeline system is out of service in my country's heating infrastructure, it is easy to cause fouling, oxidation and corrosion of the transducer , thus causing measurement influence or even measurement failure to the ultrasonic flowmeter. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an embedded ultrasonic flowmeter which is reasonable in design, easy to use and not prone to fouling, aiming at the deficiencies of the prior art. [0004] The technical problem to be solved by the present inv...
