LoRaWAN Ultrasonic Liquid Level Sensor - Battery Powered

The LoRaWAN Ultrasonic Liquid Level Sensor is a high-precision, non-contact liquid level monitoring device designed for smart tanks, chemical containers, LPG cylinders, water systems and industrial asset management. Using ultrasonic technology, it measures liquid height through the tank base, eliminating the need to drill holes or expose the sensor to hazardous liquids.

This non-intrusive design makes it ideal for monitoring toxic liquids, strong acids, fuels, alkalis, chemicals, pure water, high-pressure vessels, and sealed tanks. Installation is simple — the sensor mounts beneath the tank to detect level height safely and accurately.

Powered by an 8500mAh Li-SOCI₂ long-life battery or available in a solar-powered version, it delivers up to 5 years of operation, perfect for remote or hard-to-access locations. LoRaWAN long-range technology ensures reliable transmission across farms, industrial sites, smart cities, and utility networks.

With BLE configuration, remote LoRaWAN parameter updates, and OTA firmware upgrades, setup and fleet management are easy. Fully compatible with ProSight by ProSense as well as TTN, ChirpStack, Actility, and all major LoRaWAN platforms.

Australian Stocked & Locally Supported by ProSense. Works with ProSight and all third-party IoT software.
