Description

The Liquid Level and Temperature Probe offers a cost-efficient and long-lasting solution for monitoring water levels in various environments. Based on hydrostatic pressure sensor technology, it ensures reliable measurements even in challenging conditions — deep in the soil, wells, tanks, and surface waters.

Measurement data is automatically transmitted to the Fluxcloud and SCI portal, where it can be viewed in near real time. Users can set alarm thresholds directly in the portal, and SMS alerts notify immediately when limits are exceeded.

Through remote management features, users can modify settings, monitor battery status, perform diagnostics, carry out firmware updates, and reboot the device — all without visiting the site. The logger’s integrated GPS function displays measurement points on a map, simplifying the management of multiple monitoring locations.

Its compact design, long battery life, and versatile connectivity make it a flexible, maintenance-free solution for both research and practical applications.

Typical configuration: Pressure sensor, 3 m observation tube with 1 m filter tube, transmitter, and cloud/portal services.


Applications and Benefits

  • Groundwater monitoring: continuous tracking in agricultural and forest areas

  • Wells and irrigation basins: prevents drying and overflow, ensures water availability

  • Controlled drainage wells and subsurface drains: supports flow regulation and early blockage detection

  • Water utility groundwater zones: secures raw water supply and meets monitoring obligations

  • Sub-irrigation pump control: automatic start and stop based on water level

  • Streams and ditches: flood risk prediction and monitoring during extreme weather events

  • Restoration sites and dams: monitors water recovery and dam operation
