Oxford RF Sensors Inc., Nashville, TN, is developing an intelligent dipstick that is self-calibrating and provides simultaneous measurement of fluid level and fluid condition. The RF sensor provides fluid level measurement, independent of changes in temperature and composition, to 0.1% accuracy and measurement of changes in fluid composition to 100 ppm. Sensors are available as both rigid and flexible probes that can measure level or volume in irregular-shaped tanks. Sensors are configured to provide specific information on fluid condition, e.g., detecting water contamination or oxidation. The sensor design is available for license.
