1. 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;
an external data storage system configured to store telemetry data created by the system; 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 telemetry data includes fluid overflow data.
