ABSTRACT:
A flow control device for automatically controlling the flow of a fluid at a predetermined rate that is capable of taking measurements of the pressure of the fluid within the device while the device is functioning and that is capable of real-time adjustment of the flow rate is provided. Said device includes a casing having a casing outlet, a piston having a piston inlet and an edge, wherein said piston interfaces with the casing in a manner such that the edge is cooperable with the casing outlet to control the flow of fluid through the device. A biasing member, such as a spring, for biasing the casing with the piston is further included, as is a sensor, such as a pressure transducer, for measuring the pressure within the interior of the casing.
