Abstract
A soap film gas flowmeter comprising a hollow flow tube having opposite open ends through which a soap bubble is propelled with one open end extending into a first closed chamber housing the soap solution and the opposite open end extending into a second chamber. Inlet gas is fed into the first chamber, passed through the flowtube and discharged from the second chamber. A manually movable piston like member is provided for generating a soap bubble at the bottom open end of the flowtube. The flowtube has an opening in it for providing an open passageway for inlet gas to pass through the flowtube when the bottom open end of the flowtube is covered by the soap solution.
