Gasometer

A gasometer or gas-holder is a large container where gas is stored near normal pressure and temperature. The volume of the container follows the quantity of stored gas, the pressure comes from the weight of the movable cap. Typical volumes for big gasometers are about 50000 m³, with 60 m diameter structures.

Gasometers tend to be used for balancing purposes (making sure gas pipes operate within a safe range of pressures) rather than for actually storing gas for later use. Gas is nowadays stored in large underground reservoirs such as salt caverns. Often gas is stored in the summer when it is cheap and sold in the winter when the price goes up.

Also a gasometer is a meter for measuring the amount of gas flowing through a particular pipe.

The term 'gasometer', was originally coined by William Murdoch, the inventor of gas lighting, in the early 1800s. Despite the objections of his associates that his "gazometer" was not a meter but a container the name was retained and came into general use.
