US Patent 11592348 System and method for measuring volume and pressure

A volume measurement system for a fluid processing device includes a fluid container, an imaging unit, and a controller. The container includes a housing defining the structure of the fluid container, and a plurality of fluid chambers. The fluid chambers collect and/or store fluid from the fluid processing device, and each have a port that allows fluid to enter and/or exit the fluid chambers. The imaging unit takes images of the fluid chambers and is positioned to view a level of fluid in each of the chambers. The controller is in communication with the imaging unit and determines the volume of fluid within each of the fluid chambers based upon the viewed level of fluid in the fluid chambers.
