4G Cellular Submersible Pressure & Liquid Level Sensor – Battery Powered
A rugged 4G cellular submersible pressure and liquid-level sensor built for water, agriculture, industrial, and environmental monitoring. Designed for standalone, long-range deployments, it runs on a long-life battery and integrates seamlessly with ProSight and all third-party IoT platforms.
Australian Stocked & Supported
The 4G Cellular Submersible Pressure & Liquid Level Sensor is a high-accuracy, industrial-grade monitoring device designed for remote liquid measurement applications such as tanks, dams, bores, reservoirs, wastewater pits, and irrigation infrastructure.
Using a rugged immersion-grade pressure probe, the sensor accurately measures hydrostatic pressure and converts it into usable water depth/level data. Available in multiple depth/pressure ranges, the sensor can be deployed in shallow tanks through to deep bores and industrial vessels.
Connectivity is provided via 4G NB-IoT or LTE-M (CAT-M1), enabling long-range, direct-to-cloud communication without requiring a gateway. With an 8500mAh long-life Li-SOCI₂ battery, the device supports multi-year operation even in remote or off-grid environments.
Designed for professional IoT deployments, it supports MQTT, MQTTs, CoAP, UDP, and TCP, along with remote configuration, BLE setup, alarm thresholds, and firmware updates. Fully compatible with ProSight by ProSense, as well as all major cloud platforms.
Australian Stocked & Supported — ProSense provides full local support, configuration help, SIM setup, and ProSight onboarding.
