Anti-interference structure for ultrasonic gas meter

Abstract

An anti-interference structure for an ultrasonic gas meter includes an upper housing and a lower housing. A gas flow channel is fixedly provided in the upper housing. A side of the gas flow channel is fixedly provided with a control box. According to the anti-interference structure for the ultrasonic gas meter, in practical work, gas can enter the gas flow channel, and a signal sensor inside the gas flow channel can detect external signals. When a signal is detected, a motor is started to drive a bidirectional threaded rod to rotate. Thus, two sealing elements are driven to move in opposite directions so as to isolate the flowing gas and prevent it from continuing to flow. Then, the signal sensor sends a signal to notify personnel of inspection. A shielding layer can effectively isolate the external signal, thereby preventing the measurement accuracy from being affected by the external signal.
