The installation of a gas flow meter requires that the flange of the process pipeline must be coaxial with the flange of the flow meter and parallel to each other. An ultrasonic gas flow meter uses the principle of sound velocity difference of ultrasonic propagation, that is, it calculates the flow rate and flow of the gas by measuring the sound velocity difference of the ultrasonic airflow in the forward and reverse directions.

[0003] According to an ultrasonic gas flowmeter for reducing the axial load of the flowmeter disclosed on the patent website (authorization announcement number: CN114235066A), "The present invention discloses an ultrasonic gas flowmeter for reducing the axial load of the flowmeter, including a flowmeter body, one end of the flowmeter body is matched and connected with a gas pipeline one, and the end of the flowmeter body away from the gas pipeline one is matched and connected with a gas pipeline two, and the end of the gas pipeline one close to the flowmeter body is provided with an auxiliary clamping mechanism one, and the end of the gas pipeline two close to the flowmeter body is provided with an auxiliary clamping mechanism two, and the bottom ends of the auxiliary clamping mechanism one and the auxiliary clamping mechanism two are provided with a support base assembly, and both ends of the support base assembly are provided with a height adjustment support. Beneficial effect: It can reduce the axial load of the flowmeter, thereby improving the connection stability and connection strength of the ultrasonic gas flowmeter, avoiding loosening and damage after long-term use, and at the same time having the function of gas leakage monitoring, improving the safety of use." Based on the above, the applicant believes that there are the following defects: The ultrasonic gas flowmeter for reducing the axial load of the flowmeter includes a flowmeter body. The device can reduce the axial load of the flowmeter, thereby improving the connection stability and connection strength of the ultrasonic gas flowmeter, avoiding loosening and damage after long-term use, and at the same time having the function of gas leakage monitoring to improve the safety of use.
