Ultrasonic transducer installation structure and ultrasonic flowmeter

Abstract

The invention discloses an ultrasonic transducer mounting structure and an ultrasonic flowmeter. The flowmeter comprises an upstream pipeline, an upstream transducer mounting structure, a measuring pipeline, a downstream transducer mounting structure and a downstream pipeline. The ultrasonic transducer mounting structure comprises a structure body and an ultrasonic transducer. The structure body comprises a first mounting connector, a second mounting connector and a fluid channel. The first mounting connector is used for mounting the measuring pipeline, and the second mounting connector is used for mounting the upstream pipeline or the downstream pipeline. The fluid channel is formed inside the structure body and arranged between the first mounting connector and the second mounting connector. The ultrasonic transducer is further mounted on the end side, opposite to the first mounting connector, of the structure body. The emitting surface of the ultrasonic transducer directly faces the first mounting connector, and ultrasonic waves sent from the ultrasonic transducer are made to be perpendicular to the cross section of the fluid channel and the cross section of the measuring pipeline and to enter fluid of the measuring pipeline.

Description

technical field [0001] The invention relates to the field of flow measuring instruments, in particular to an installation structure of an ultrasonic transducer in an ultrasonic flow meter. Background technique [0002] Ultrasonic flowmeter is a kind of measuring instrument that calculates the flow rate of fluid by measuring the time difference between forward flow and reverse flow of ultrasonic waves in fluid. Ultrasonic flowmeter has the characteristics of simple structure, fast response, large measurement range, good stability and high precision. In addition, the ultrasonic flowmeter is also a non-contact measuring instrument, which will not cause pressure loss to the measuring pipeline, has no requirements on the measuring medium, and can measure the flow rate of various gases and liquid media. The above characteristics make ultrasonic flowmeters widely used, and many applications of ultrasonic flowmeters can be seen in various fields such as industry, agriculture, medic...
