Devices, systems, and methods for measuring fluid level using radio-frequency (RF) localization

A system for measuring a fluid level, comprising:

• at least one remote float device configured to emit at least one radio frequency (RF) signal and configured to float on the surface of a fluid to be measured;
• and
• a processor configured to:
• receive at least one RF signal from at least one RF antenna, emitted from the at least one remote float device;
• analyze the at least one RF signal from the at least one RF antenna;
• and calculate a location of the at least one remote float device based upon the analyzed at least one RF signal, wherein the location of the at least one remote float device corresponds to a level of the fluid;
• wherein the at least one remote float device comprises at least one auxiliary sensor selected from the group consisting of a microphone, a pressure transducer, and a camera.

A system for measuring a fluid level, comprising:

• at least one remote float device configured to emit at least one radio frequency (RF) signal and configured to float on the surface of a fluid to be measured;
• at least one anchor device having at least one RF antenna positioned at a fixed location over the surface of the fluid to be measured;
• and
• a processor configured to:
• receive at least one RF signal from at least one RF antenna, emitted from the at least one remote float device;
• analyze the at least one RF signal from the at least one RF antenna;
• and
• calculate a location of the at least one remote float device based upon the analyzed at least one RF signal, wherein the location of the at least one remote float device corresponds to a level of the fluid;
• wherein the processor is in operable communication with the at least one anchor device.
