Abstract

The invention discloses an ultrasound device and a method using same to measure fluid flow; the ultrasound device comprises a fluid pipeline used for coupling to one or more pipes and an ultrasound transducer arranged on the pipeline; the pipeline comprises a main body having a flow channel and a heat isolation structure coupled to the main body; the heat isolation structure comprises organic polymer material, and used for thermal-isolating the ultrasound transducer from the flow channel; the invention also relates to the method using the ultrasound device to measure fluid flow.

Description

technical field [0001] The present invention relates to an ultrasonic device and a method of measuring fluid flow with the ultrasonic device. Background technique [0002] Ultrasonic devices are widely used to measure the physical properties of fluids, such as liquids and gases, flowing in pipelines. For example, based on ultrasonic echography (ultrasonicichography) and Doppler theory (Doppler theory), ultrasonic transducers can be used to obtain fluid velocity information. Ultrasonic transducers are generally installed on the pipe wall, and the ultrasonic pulse waves emitted from the ultrasonic transducer propagate into the fluid in the pipe. The impurities in the fluid reflect the ultrasonic waves back, and the transducer receives the echo. According to the Le principle, the fluid velocity can be calculated by a known formula. The velocity flow pattern of the fluid can be obtained based on the velocity information, which is very important for the study of the physical ch...
