A new method for detecting tightness of gas meter is presented by use of multi-sensors. A single processor AT89C52 is adopted as the main controller in detection which accomplishes fast data acquisition and processing. This paper mainly introduces the principles of the detecting method, the design ideas of the hardware, software and air-circuit that achieves automatic measuring. Compared with traditional wet measuring method of gas meter, the new method can quantitatively detect the tightness, and has advantages of high precision and efficiency. It is mostly suitable for the IC card gas meter which cannot be measured under the water.
