Abstract
The following specification describes a flowmeter in which a tube secured to a biased bellows for movement therewith receives a rod to define a passage having a small radial dimension relative the length of rod received in the tube. The passage provides a pressure drop, which varies linearly with flow rate and moves the bellows and tube to a position corresponding to the flow rate. An indicator rod extends from the tube through a wall of the meter housing to provide an indication of the bellows position and therefore the flow rate.
