The diaphragm in a gas meter functions to do what?

The diaphragm in a gas meter is essential for measuring the flow of gas. It operates by flexing in response to the pressure of the gas that flows through the meter. As gas moves through the meter, it causes the diaphragm to expand and contract. These movements, in turn, drive gears that register the total volume of gas that has passed through the meter. This mechanical action is what allows the gas meter to provide an accurate reading of gas consumption.

Understanding this function highlights the importance of the diaphragm in ensuring that billing for gas usage is based on precise measurements, enabling utility companies to charge customers accurately for the gas they consume.
