How to Buy


The tank level float sensor detects when the level in a tank reaches a given level using a mechanical float device. When the mechanical float rises or falls (the level increases above or decreases below the mechanical float), an alert is sent to the wireless network.


  • Tank level detection for fluids
  • Water overflow detection
  • Fuel low detection
  • General purpose liquid level sensing
