Dragino DDS20 | LoRaWAN Ultrasonic Non-Contact Liquid Level Sensor

The Dragino DDS20 is an innovative LoRaWAN® liquid level sensor designed for scenarios where tank integrity cannot be compromised. By utilizing ultrasonic sensing technology, the DDS20 measures the height of liquid from the bottom exterior of the container. This non-invasive method eliminates the need to drill holes or open the tank, making it the safest choice for monitoring pure liquids, strong acids, alkalis, or toxic substances in high-pressure or airtight environments.

Non-Invasive Sensing Excellence

External Installation The measuring probe attaches directly to the bottom of the tank, ensuring the sensor never touches the liquid. Precision Monitoring Highly accurate ultrasonic waves provide real-time level data through various container materials like steel or plastic.

Smart Liquid Control Scenarios

• Hazardous Material Management: Safely monitor toxic or corrosive chemicals without risk of sensor degradation or leaks. • Food & Beverage: Maintain hygiene standards by monitoring pure liquids from outside the container. • Industrial Storage: Ideal for high-pressure airtight containers where internal probe installation is impossible.

Dragino Power Options

• Model LB: Powered by a non-rechargeable 8500mAh Li-SOCI2 battery for long-term field use. • Model LB2: High-capacity version with a non-rechargeable 19000mAh battery for extended maintenance cycles. • Model LS: Sustainable solar-powered version with a 3000mAh rechargeable battery for continuous operation.
