Dragino DDS20 | Non-Contact Cellular Liquid Level Sensor (NB-IoT) Clearance Powered from standard AC mainsThe Dragino DDS20 is a carrier grade Non Contact Ultrasonic Liquid Level Sensor engineered for high precision monitoring in industrial and utility sectors. Unlike traditional sensors, the DDS20 installs externally at the bottom of a container, quantifying liquid height through the tank wall. This non invasive method is critical for handling toxic substances, strong acids, or alkalis in airtight, high pressure containers. Utilizing NB IoT cellular
