Genus Gas Meter G1.6 (SKG16) is positive displacement gas meter. Within the meter there are two chambers formed by moveable 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 diaphragm expand and contract, levers connected to cranks convert the linear motion of diaphragm into rotary motion of a crank shaft which serves as the primary flow element. This shaft drives an odometer counter mechanism for accurate volume measurement.
