Lev’O sensor – LoRaWAN


The Lev’O sensor reads the fill level of tanks, cisterns and cavities when their geometry is known.

The Lev’O sensor measures the absolute pressure of a liquid (water, fuel oil, oil, fertilizer, etc.) whether in a buried or aboveground tank, or in movement in a tank truck, then transmits the data used to calculate the fill level over a public or private LoRaWAN™ radio network.


  • LoRaWAN™, Class A
  • Autonomous sensor-probe assembly
  • Easy to install and use
  • Remote level probe:
    – Accuracy: 3% between 2 and 4m
    – Probe (only) AtEx Zone 2
    – Small diameter body for easy insertion
  • Measurements at regular intervals

  • IP65 sensor and permanently submersible probe


  • Use cases :
    Smart industry: level monitoring in tanks
    Smart farming: level monitoring in fertilizer or milk tanks or silos
  • Remote level reading of a tank: liquid fertilizer, fuel oil tank, to optimise delivery rounds
  • Monitoring the level of an overflow sump associated with a lift pump
  • Control of cutting oil level in a process
  • Remote reading of fuel oil, lubricant, liquid fertilizer or milk in a container:
    – Buried, aboveground, indoor or outdoor tank (according to the nature of the liquid)
    – Tank truck with possible macro geolocation (depending on the performance of the public network)
  • Optimised distribution logistics
  • Estimated consumption for intermediate billing
