principle of operation

Like the principle of ancient locomotives, gas meters rely on the pressure of gas to push the drum counter to count. Specifically, the cylinder and piston mechanism in the locomotive should be greatly simplified, with the cylinder replaced by bellows and the piston replaced by diaphragm.

The middle part of the film is clamped by the metal sheet, which is a hard "hard core" and cannot be bent, but the surrounding film is very soft, so that the hard core can move left and right in the box. The film divides the space in the box into two parts, and each part forms two "air chambers", namely I, II, III and IV in the picture.

Each air chamber has a vent through which air can be introduced or discharged. When the mouth of the left chamber sucks air and the mouth of the right chamber exhausts air, the pressure of the gas acts on the thin film, making the hard core move to the right. On the other hand, if the right side sucks air and the left side exhausts air, the hard core moves to the left.
