Abstract
A gas meter, including flexible diaphragms which shift within chambers into which the gas to be metered is alternately admitted and exhausted, is adapted for a variety of different mounting configurations by the selection of appropriate top and bottom covers. In one embodiment, each of the top and bottom covers includes a gas pipe connection with these connections being arranged parallel to each other. In a second embodiment, the top cover is internally divided to provide separate paths for inlet and outlet gases while the bottom cover constitutes a blank plate.
