Ever wondered what a gas meter is needed for or how a gas meter works? A meter is a device that is able to measure the flow of gas. They are used in homes as well as commercial and business properties. There are three main types of gas meters: a turbine meter  (mainly used to measure gas in large industries), rotary meters (which are more precise, can hold more volume of gas and work at a higher pressure) and diaphragm meters which come in some off the shelf sizes: U6, U16, U25, U40, U65, U100 and U160. A U6 can normally deliver up to around 64 kilowatts of gas and a U160 can deliver up to around 1700 kilowatts (kW).

The most common type of gas meter is a diaphragm meter that has two chambers formed by flexi diaphragms that expand and contract like a pump. Gas meters are important as they ensure that there is safe pressure coming from the gas mains supply and ensure that gas usage is monitored for billing purposes.
