Abstract
A flowmeter for liquids includes a hollow housing having an internal metering chamber, at least two liquid connections coupled to the housing and communicating with the metering chamber for establishing a liquid flow therethrough, a generally disc-shaped wobble plate having a centrally-disposed spherical wobble center mounted within the metering chamber and non-contacting coacting signal transmitter elements associated with the housing and wobbler plate for generating signals which proportionally correspond to the wobble frequency of the wobble plate. The flowmeter is especially suited for measuring small or weak liquid flows.
