摘要： One embodiment of the present invention can include a flow control device comprising an inlet, an outlet, a pressure loss element between the inlet and outlet, a pressure sensor located upstream from the constriction configured to measure a first pressure of a fluid flowing through the flow control device, a pressure sensor located downstream from the constriction, configured to measure a second pressure of the fluid flowing through the flow control device; and a controller coupled to the first pressure sensor and the second pressure sensor to generate a valve drive signal. The controller can generate a valve control signal based on a differential between the first pressure and the second pressure during a first mode of operation. The controller can also generate a valve control signal based on a measured pressure at a particular pressure sensor during a second mode of operation. The mode of operation can automatically switch.

摘要： Systems and methods for reducing temperature variations induced by fluid handling equipment in process fluids by separating heat-producing portions of the control equipment from portions of the equipment which handle or are in close proximity to a fluid flow path. In one embodiment, the fluid handling components are contained in a first enclosure, while the heat-generating components are contained in a second enclosure. An air gap is maintained between the two enclosures to provide thermal isolation of the fluid handling components from the heat-generating components. In one embodiment, the air gap is maintained by connecting the two enclosures using insulating spacers. Interconnects between components in the two enclosures may be routed through an insulating tube that is sealed at each end to prevent heat transfer through the tube.
