Liquid-gauging systems for estimating amounts of liquid within collapsible bladders. In some embodiments, a liquid-gauging system of this disclosure includes one or more liquid-gauging sensors that each output a signal relating to an amount of liquid within a corresponding collapsible bladder. In some embodiments, each liquid-gauging sensor comprises a variable capacitor having capacitor plates located so that the spacing between the capacitor plates changes with changing amounts of liquid within the collapsible bladder. In some embodiments, each liquid-gauging sensor comprises a pressure sensor for measuring forces, such as gravitational forces, that change with changing amounts of liquid within the collapsible bladder. In some embodiments, a liquid-gauging system is configured for an aircraft or other moving vehicle and includes one or more additional sensors to adjust the estimating process to account for changes in attitude of the vehicle during use. Corresponding methods, liquid-storage systems, and collapsible bladders are also disclosed.
