 2. Technical Features:

G type steel case gas meters are positive diaphragm meters, within the meter there are two chambers formed by movable diaphragms. With the gas flow directed by internal valves, the chambers alternately fill and expel gas, producing a near continuous flow through the meter. As the diaphragms expand and contract, levers connected to cranks convert the linear motion of the diaphragms into rotary motion of a crank shaft which serves as the primary flow element. This shaft then can drive an odometer-like counter mechanism.
