The surface topography characteristics of the working surface of the gas valve cover of a gas meter can be used to quantitatively evaluate the sealing performance of the gas valve. A set of surface topography measurement devices based on line laser triangulation was fabricated to study the relationship between the flatness of the valve cover and valve tightness. In the experiment, several qualified and unqualified valve covers were selected for the measurement, and the original data of the three-dimensional topography of the valve cover surface were obtained; the data were tilted and corrected to obtain the flatness error of the valve cover surface. The experimental results showed that when the sampling data point interval is optimized, the flatness error can be used to distinguish the air valve cover sealing characteristics. When the X-axis sampling interval is 0.1 mm and the Y-axis sampling interval is 0.02 mm, the air valve cover rotates at 0°, and the flatness error threshold for distinguishing whether the air valve is qualified or not is approximately 0.1105 mm. Tightness testing method is verified, which provides an important foundation to realize higher accuracy measurement of gas meter.
