Abstract
A flowmeter for measuring the quantitative flow of fluids such as gases passing therethrough is disclosed and includes a housing forming at its upper end a centrally located tubular guide. The housing has a centrally located chamber which terminates at its upper end at the tubular guide. The chamber is in communication with a gas outlet. A gas tube is mounted in the chamber and has a fluid escape slot which opens to the chamber. The gas tube communicates at its lower end with a gas inlet. A float is provided which is adapted to slidably move up and down within the gas tube and the tubular guide of the housing. A sight glass is mounted on the upper portion of the housing co-axial with the float for viewing movement of the upper portion of the float therein. The sight glass is sealed at its upper end forming fluid shock absorbing means to accommodate and compensate for rapid upward and downward movement of the float.
