System and method for identifying a fill volume of a fluid chamber

A method for determining the volume of fluid in at least one fluid chamber of a fluid injection system comprising a fluid injector, the method comprising the steps of:

• positioning one or more sensors relative to the at least one fluid chamber, wherein the one or more sensors are in communication with at least one processor in communication with the fluid injector;
• detecting with the one or more sensors a position of a liquid-gas interface of the fluid contained in the at least one fluid chamber;
• taking position data of the liquid-gas interface of the fluid contained in the at least one fluid chamber with at least one of the one or more sensors;
• determining the position of the liquid-gas interface of the fluid in the at least one fluid chamber from the position data;
• calculating the volume of fluid contained in the at least one fluid chamber based on the position of the liquid-gas interface of the fluid in the at least one fluid chamber;
• and at least one of:
• i) displaying on a display in communication with the at least one processor the volume of the fluid contained in the at least one fluid chamber;
• ii) enabling the fluid injector to perform an action;
• iii) informing a user of an insufficient volume and allowing the user to install a fluid container having a sufficient volume;
• iv) informing the user of the insufficient volume and allowing the user to continue with a system-adjusted volume or a user-adjusted volume;
• and
• v) disabling the fluid injector from performing the action.
