[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to a dual-channel ultrasonic flowmeter with an explosion-proof function. Background Art

[0002] An ultrasonic flow meter is an instrument that uses ultrasonic technology to measure fluid flow. It installs an ultrasonic sensor on the fluid pipeline and uses the difference in the propagation speed of ultrasonic waves in the fluid to calculate the fluid flow rate. This flow meter has the advantages of non-contact measurement, high precision, wide measurement range, and the ability to measure fluids with low electrical conductivity. At the same time, it also has functions such as real-time monitoring and remote data transmission. It is widely used in industry, environmental protection, water treatment and other fields. The installation and maintenance of ultrasonic flow meters are relatively simple. There is no need to destroy the pipeline. Only the sensor needs to be pasted on the outer wall of the pipeline. During use, care must be taken to avoid strong electromagnetic interference and high temperature environment to ensure measurement accuracy and stability. In short, ultrasonic flow meters are an efficient and accurate fluid measuring instrument that provides important technical support for industrial production and environmental protection.

[0003] Ultrasonic flowmeters are used to detect fluid flow. Existing ultrasonic flowmeters will produce high-temperature and high-pressure gas after long-term use. If this gas is not discharged in time, the ultrasonic flowmeter may be damaged, reducing the efficiency of the ultrasonic flowmeter.

[0004] Therefore, it is necessary to redesign and modify the ultrasonic flowmeter to effectively prevent the existing ultrasonic flowmeter from generating high-temperature and high-pressure gas during long-term use. If it cannot be discharged in time, the ultrasonic flowmeter may be damaged, reducing the efficiency of the ultrasonic flowmeter. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
