A Gas Volume Shaker is a tool that is used to measure the volume of gas in a container, such as a cylinder or a canister, by shaking or vibrating the container. The shaker typically consists of a mechanism to shake or vibrate the container, a pressure gauge, and a temperature sensor.

The gas volume shaker works by shaking or vibrating the container to remove any air bubbles that may be trapped in the gas. The pressure and temperature are then measured, and the volume of gas in the container is calculated using the Ideal Gas Law (PV=nRT).

The gas volume shaker is used in the gas and oil industry, as well as in other industries such as chemical manufacturing and packaging, where it is important to ensure that containers are properly filled with gas and that there are no leaks. The test can be done on different types of gases, such as natural gas, propane, helium, and other industrial gases.
