Claim 0:
1. A system for measuring a fluid level, comprising:
at least one anchor device having at least one radio-frequency (RF) antenna positioned at a fixed location over a surface of a fluid to be measured;
at least one remote float device configured to emit at least one RF signal and configured to float on the surface of a fluid to be measured; and
a processor in operable communication with the at least one anchor device, the processor configured to:
receive the at least one RF signal from the 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;
measure a time-of-flight of the at least one RF signal between the at least one remote float device and the at least one anchor device; and
calculate a location of the at least one remote float device based upon the analyzed at least one RF signal received by the at least one RF antenna, wherein the location of the at least one remote float device corresponds to a level of the fluid.
