Abstract

An apparatus for determining and controlling characteristics of a fluid is provided that includes a substrate, a heating circuit, and a sensing circuit applied on the substrate by a layered process. A control module is in communication with the heating circuit and the sensing circuit for determining, for example, type, concentration, liquid level, and temperature of the fluid, which in one form is a urea solution.
