Abstract
A system and method are disclosed, that allow for the determination of a mass of a fluid within a container by first vibrating an external surface of a container, where the container contains a fluid (such as a compressed fluid, a gas, a liquid, a mixture of a gas and liquid, or a supercritical fluid). Then, vibration data is received at the external surface of the container, and the vibration data is then converted into one or more frequencies. The mass of the fluid in the container is then estimated based on the one or more frequencies.
Claims46
A sensor system, comprising:
- an activation and detection subsystem configured to be positioned on or near an external surface of a container containing a fluid, the activation and detection subsystem configured to:
- cause a vibration at a range of predetermined frequencies at the external surface of the container;
- receive vibration data at the external surface of the container;
- one or more processors operably communicating with the activation and detection subsystem, the one or more processors configured to, collectively:
- receive the vibration data from the activation and detection subsystem;
- and
- determine an estimated mass of the fluid based on the vibration data.
A method for determining a mass of a fluid within a container, the method comprising:
- vibrating a surface of a container with a range of predetermined frequencies, the container containing a fluid;
- receiving vibration data at or near an external surface of the container;
- determining a resonance frequency based on the vibration data;
- and
- determine an estimated mass of the fluid based on the resonance frequency.
