The DR7000 Series (radar) and DR7100 Series (time domain reflectometry) incorporate state-of-the-art features and components, including an easy-to-navigate display with choice of touch screens (tank illustration, bar graph, oscilloscope, signal and reflectivity screen), easy installation and set up. Users simply fit the 2-wire level gauges to a tank or storage vessel, wire them up and turn them on. The gauge tests itself to make certain its electronics are working correctly. An installation wizard walks the user through a series of simple questions to define the tank and product measured. The DR7000 Series utilizes Frequency Modulated Continuous Wave (FMCW) technology that offers superior signal processing capabilities. The DR 7100 Series relies on Time Domain Reflectometry (TDR) technology, which uses an electromagnetic wave guided by a metallic rod or flexible cable to determine the distance, level and volume. TDR-based level sensors use less energy than airborne radar technologies and are especially suited for vessels with internal obstructions.
