20100327884	Liquid level and quality sensing apparatus, systems and methods using EMF wave propagation - A liquid level, composition and contamination sensor generates an RF signal across a resonant circuit that includes a variable inductor and capacitor. The resulting electromagnetic radiation is propagated into the liquid and changes in impedance and resonance of the resonant circuit that result from changes in the conductivity and dielectric properties of the liquid, which are proportional to liquid content and volume, are detected. The conductivity and dielectric properties of the liquid are measured, based on the changed impedance and resonance of the resonant circuit, and are compared to determine aging and contamination of the urea solution by other liquids. Also, an optical sensor may be submerged in the liquid to determine the refractive index of the liquid. The refractive index of the liquid may be used to determine: if the liquid is water or a urea solution; the concentration of a urea solution.	12-30-2010
