A Mariotte bottle is a device that allows constant flow of a fluid from a container, even when the fluid level in the container changes. It is named after Edme Mariotte (1620–1684), a French physicist, who, independently from Boyle, discovered the law that states that the volume of a gas varies inversely with its pressure. Mariotte bottles have a wide range of applications in engineering and science (such as fuel supply) and are used in a variety of hydrologic applications ranging from river discharge gauging to infiltration measurement.
