The Need

Tank checks should not require another trip.

Remote tanks can be difficult to inspect frequently, while unexpected use or delayed refilling can become an operational problem. Users need a current reading they can trust without site WiFi, local gateways, or manual drive-by checks.

The Approach

Make the hardware and software one clear service.

A self-contained solar unit measures the water surface with radar and sends readings through its own cellular connection. Tank calibration converts sensor distance into meaningful litres and percentage values.

What It Supports

Useful answers instead of raw sensor data.

  • Solar-powered radar tank sensing with no site WiFi requirement.
  • Direct cellular readings every 15 minutes, day and night.
  • Current level in litres and percentage at a glance.
  • Daily usage, refill events, level history, and sensor-distance graphs.
  • App and email alerts for changes that need attention.
  • Shared access for owners, staff, family, or contractors.
