Flow control device, method and production adjustment arrangement

摘要

A flow control device includes, a body defining at least a portion of a flow passageway, at least one movable member in operable communication with the body, movable between at least a first position that provides a first restriction to flow through the flow passageway and a second position that provides a second restriction to flow through the flow passageway, and a circuit in operable communication with the at least one movable member that is configured to sense conductivity of fluid flowing through the flow passageway and to promote movement of the at least one movable member to move from the first position to the second position in response to a change in conductivity of fluid flowing through the flow passageway.

1. A flow control device comprising:
a body defining at least a portion of a flow passageway; at least one movable member in operable communication with the body, movable between at least a first position that provides a first restriction to flow through the flow passageway and a second position that provides a second restriction to flow through the flow passageway; a circuit in operable communication with the at least one movable member and in operable communication with a fluid flowing through the flow passageway, the circuit being configured such that electrical current is flowable from one conductor to another conductor of the circuit through the fluid in the flow passageway such that increases in conductivity of the fluid allows electrical current to flow directly through the fluid and the same electrical current is flowable through an element to cause movement of the at least one movable member from the first position to the second position; and one or more batteries in operable communication with the circuit, the one or more batteries supplying the electrical current to the circuit flowing directly through the fluid.
