ABSTRACT:
A fluid flowmeter of the venturi type is disclosed in which a throat is fed between complementary surfaces of a duct and a control member. Relative movement between the duct and the control member in response to the flow of fluid through the meter serves to enlarge the throat as the flow rate increases, and operation over a wide range of flowrates is thereby made possible. A measure of fluid flowrate can be obtained from fluid pressure measurements at the throat and at a position upstream thereof. An advantage over one prior art device is that the throat position remains substantially constant during relative movement of the complementary surfaces, so that sensing of the throat pressure is simplified.
