Abstract
The present invention is directed to system and method for determining a fluid level. The system comprises a sensing rod assembly comprised of releasably connectable rod segments. Each rod segment carries a processor and a plurality of inductors. Each inductor generates a position signal responsive to a float signal. A float assembly comprises a housing containing a circuit having an integrally formed coil periodically energizable by a processor to emit the float signal. A control assembly receives the generated position signals and determines the fluid level. The method comprises providing releasably connectable rod segments with inductors that generate a position signal responsive to a float signal, determining a sensing rod assembly length, forming the sensing rod assembly, disposing it within a container, providing a float assembly periodically actuated to generate a float signal, generating position signals responsive to the float signal and analyzing those signals to determine the fluid level.
