Three different designs of gas meters are in common use, depending on the total volume of gas to be measured.

These are the most common type seen in most installations and almost all residential installations. Within the meter are two chambers formed by movable diaphragms. With the gas flow directed by valves, the two chambers fill from the gas source and empty into the gas load, alternating their roles so that gas delivery to the load is essentially continuous. As the diaphragms expand and contract, levers connected to cranks convert the linear motion of the diaphragms into rotary motion which then drives the counter mechanism.
