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 \u003cstrong\u003etoxic substances, strong acids, or alkalis\u003c\/strong\u003e in airtight, high-pressure containers. Utilizing \u003cstrong\u003eNB-IoT\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection style=\"margin-bottom: 35px;\"\u003e\n\u003ch3 style=\"color: #7765e3;
