Abstract: In one aspect, a peritoneal dialysis system includes a tray for supporting a bag that can receive dialysate from a source of dialysate, multiple force sensors disposed adjacent a portion of the tray that is in contact with the bag when the bag is supported by the tray, and one or more processors configured to receive data from the multiple force sensors and to determine, based on the data, an amount of dialysate contained in the bag.

Abstract: A fluid control platform that may control various fluid control components and is scalable by connecting with additional substantially identical platforms, as well as related systems, methods of manufacturing the same, and methods of fluid control are disclosed. The platform may include a programmable controller, a power supply, a data input, a data output device, and/or a networking connection, among other things. A coordinated fluid control system may include multiple networked platforms, which may be networked to each other in, for example, a ring. The programmable controller may be provided with hardware that permits operation of each of a plurality of fluid control components, some of which may be intelligent fluid control components.
