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 without requiring a gateway.

Advanced Sensing & Field Efficiency

Rugged Industrial Build Housed in an IP66-rated enclosure, the DDS20 is designed to withstand harsh outdoor deployments and industrial washdown environments.
Easy Wireless Config Supports BLE (Bluetooth Low Energy) for smartphone configuration and OTA updates, simplifying maintenance and device setup in the field.

Power Configuration Options

Available in three distinct power variants to meet your specific maintenance and longevity goals:

  • Model NB: 8500mAh Non-Rechargeable battery for standard cellular use.
  • Model NB2: 19000mAh Non-Rechargeable battery for maximum field life.
  • Model NS: 3000mAh Rechargeable Solar-powered battery for perpetual autonomy.

Professional Usage Scenarios

• Hazardous Material Tracking: Safely monitor levels of corrosive or toxic chemicals without opening containers.
• Smart Gas & Fuel: Monitor propane or fuel tanks in remote areas to optimize refilling logistics and prevent stockouts.
• Food & Beverage: Measure pure liquid levels in high-pressure airtight containers while maintaining strict hygiene.
