[0002] In various industrial applications, gas flow meters are very important devices used to measure the flow of gas for monitoring, control and management. Ultrasonic flow meters are a commonly used flow measurement device that uses the propagation speed of ultrasound to measure the speed and volume of fluid flow. In some specific industrial scenarios, there may be impurities or particulate matter in the gas flow, so it is of great significance to design a gas ultrasonic flow meter with filtering function.

[0003] The conventional gas ultrasonic flowmeter in existing life does not distinguish the detected gas when in use. When the gas contains impurities such as oil, moisture, dust, etc., it will cause serious damage to the flowmeter itself, and the metering effect is not ideal. Therefore, a gas ultrasonic flowmeter with filtering function is proposed to address the above shortcomings. Utility Model Content

[0004] The purpose of the utility model is to provide a gas ultrasonic flow meter with a filtering function in order to solve the above-mentioned problems. By adding a filter plate, the gas in the pipeline is filtered to prevent impurities such as oil, moisture, dust, etc. contained in the gas from damaging the flow meter itself, thereby increasing the service life of the device and solving the problems mentioned in the background technology.

[0005] In order to solve the above problems, the utility model provides a technical solution:

[0006] A gas ultrasonic flow meter with a filtering function comprises a measuring tube, wherein a plurality of dampers are fixedly connected at both ends of the measuring tube, an upper mounting ring is fixedly connected at the output ends of some of the dampers, an insert block is fixedly connected at both ends of the upper mounting ring, and a slot is provided inside the insert block.

[0007] As a preferred solution of the utility model, the output end of the other part of the damper is fixedly connected to a lower mounting ring, invisible grooves are provided inside the two ends of the lower mounting ring, a telescopic rod is fixedly connected inside the invisible groove, and a clamping block is fixedly connected to the output end of the telescopic rod, and the outer surface of the clamping block is clamped with the inside of the clamping groove.

[0008] As a preferred solution of the utility model, a slot is provided inside the lower mounting ring, and the inside of the slot is engaged with the outer surface of the insert block.

[0009] As a preferred solution of the utility model, the outer surface of the measuring tube is fixedly connected to a line pole, and the top of the line pole is fixedly connected to a display board.

[0010] As a preferred solution of the utility model, two fixing rings are fixedly connected to the outer surface of the measuring tube, and multiple installation grooves are provided on the outer surfaces of the two fixing rings. Both ends of the measuring tube are fixedly connected to docking blocks, and multiple docking ports are provided inside the docking blocks.

[0011] As a preferred solution of the utility model, a filter plate is arranged on the inner side of the upper mounting ring, and the outer surface of the filter plate is movably connected to the inner side of the lower mounting ring.

[0012] The beneficial effects of the utility model are as follows: by installing a filter plate, the gas in the pipeline is filtered to prevent impurities such as oil, moisture, dust, etc. contained in the gas from damaging the flow meter itself, thereby increasing the service life of the device, preventing damage during use that would delay measurement work, ensuring the stability of the device, reducing the maintenance cost of the device, and improving the economic benefits of the device.
