The Dragino NDDS20 is a non-contact NB-IoT Ultrasonic liquid level sensor. Connects instantly to Semvar for data visualisation, reporting and alerting.
NDDS20 uses a non-contact method to measure the height of liquid in a container without opening the container. NDDS20 uses ultrasonic sensing technology for distance measurement. NDDS20 is of high accuracy to measure various liquids such as toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure airtight containers.
Distance / LevelThe NDDS20 sensor is installed directly below the container to detect the height of the liquid level. This removes the need to create a hole in the container to be tested. This non-contact measurement makes the measurement safer, easier and possible for risky situations.
NDDS20 is powered by an 8500mAh Li-SOCI2 battery, It is designed for long-term use up to 5 years. Battery life depends on the use environment, update period & uplink method.
The IP66 Waterproof Enclosure ensures reliable operation in diverse conditions. Shielded against water and dust, this enclosure enhances the durability and accuracy of the ultrasonic sensor, making it ideal for various liquid-level monitoring applications. Whether indoors or outdoors, the IP66 protection ensures consistent performance, providing a robust solution for precise liquid level measurements in any environment.
Dragino NDDS20 NB-IoT Liquid Level Sensor can be connected to Semvar for instant data visualization, dashboards, alerting, and machine learning.
