The tools that should be used to record the most complete data about a gas are a manometer and a thermometer. Pressure and temperature are important measurements for a gas since from these data we can calculate any other properties of the gas.
The most common method of measuring gas is through an orifice meter. Gas flows through a piece of straight pipe with an orifice plate inserted in the middle. The orifice plate is a steel circular plate with a hole in the middle; the hole is smaller than the internal diameter of the pipe. The plate is placed perpendicular to the gas flow, and is sealed so that all the gas flows through the hole. The hole is tapered, meaning that the edge of the orifice hole is sharp.
