Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic gas meters, in particular to a flexibly detachable protective structure of an ultrasonic gas meter. Background Art

[0002] Ultrasonic flow meter (ultrasonic gas meter) is a new type of gas meter different from traditional mechanical diaphragm flow meter and electronic diaphragm flow meter. Its working principle is: use the time difference method to measure the gas flow rate, that is, by measuring the difference in the speed of ultrasonic signals when they propagate downstream and upstream in the fluid to reflect the flow rate of the fluid. Because the error caused by the change of sound velocity with fluid temperature in the time difference method is small, the accuracy is high and it is widely used.

[0003] In the prior art, such as CN214066230U disclosed on the Chinese patent website, a protective device for an ultrasonic gas meter is provided, in which an inspection door is hingedly connected by hinges, and a cleaning component is arranged on the end face of the inspection door. An observation window is arranged on the inspection door, which can prevent moisture from damaging the gas meter body and is beneficial to improving the service life of the gas meter body. However, the protective box and moisture-proof box of this ultrasonic gas meter are fixedly connected, and the two structures cannot be flexibly disassembled and assembled, which makes it inconvenient to maintain and replace the protective box or the moisture-proof box separately, affecting the working efficiency and service life of the ultrasonic gas meter. Therefore, a flexibly detachable ultrasonic gas meter protective structure is proposed to solve the problems mentioned in the above background. Summary of the invention
