The UCL-520 is a two-wire ultrasonic transmitter that provides non-contact level measurement up to 26.2′ (7.98 m) and is built for challenging ultra pure, corrosive or waste liquids. The highly accurate Continuous Level sensor is easy to install in applications with limited mounting options and space. The UCL-520 is push button calibrated and is broadly selected for atmospheric bulk storage, day tank and waste sump applications.
