    Abstract: 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 va... Show More
