Cellular Solar-Powered Ultrasonic Liquid Level Sensor – Non-Contact Tank Monitor

The Solar-Powered Cellular Ultrasonic Liquid Level Sensor is a fully autonomous, industrial-grade solution for remote tank level monitoring. Designed for long-term outdoor operation, the built-in solar panel and rechargeable Li-ion battery ensure continuous, maintenance-free performance — even in remote, off-grid locations.

Using precision ultrasonic technology, the sensor measures liquid height from outside the tank, eliminating the need to drill holes or contact the liquid. This non-contact method is ideal for hazardous, corrosive, pressurised, or sealed tanks including diesel, chemical drums, IBCs, LPG cylinders, and irrigation water storage.

With 4G LTE Cat-M1 and NB-IoT connectivity, the unit transmits real-time measurements directly to the cloud without requiring a LoRaWAN network. It supports MQTT, MQTTs, UDP, TCP, and CoAP, making it compatible with ProSight by ProSense and all major IoT platforms.

The solar charging system provides continuous power to the internal 3000mAh lithium battery, delivering multi-year service with zero manual intervention. BLE mobile configuration, downlink control, and OTA firmware updates ensure simple deployment and fleet management.
