Dragino DDS20 | Non-Contact Cellular Liquid Level Sensor (NB-IoT)
Description
Description
The 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 connectivity, it provides a direct-to-cloud data path, ensuring reliable telemetry for remote tanks across Europe and the Middle East without requiring a gateway.
