Abstract
A portable device, a system and a method measure a volume of a vessel, such as, for example, an expandable bag and/or a pressurized vessel, using a light-emitting diode (LED) located within the portable device. A shaft which may extend from the portable device may be introduced into the vessel. The light emitted by the LED may travel through the shaft into the vessel, and light reflected by the interior of the vessel may travel through the shaft into the portable device. The shaft may be introduced into a container in which at least a portion of the vessel is located. The light emitted by the LED may travel through the shaft into the container, and light reflected by the interior of the container and/or the exterior of the vessel may travel through the shaft into the portable device.
