Contactless Fluid-Level Measurement Using A Reflectometer Chip

By Bruce Hemp, Senior Applications Engineer

Fluid-level measurements can be accurately measured through the wall of a nonmetallic tank by placing an air-dielectric transmission line up against the side of the tank and sensing the RF impedance. This article provides an empirical design example that illustrates how a reflectometer device such as the Analog Devices ADL5920 can simplify the design. To learn more, download the full article.
