The LEV’O SENSOR measures the filling level of tanks, cisterns and cavities when the geometry is known. It transmits the absolute pressure of a liquid (water, fuel, oil, fertilizer, etc.) whether it is in a buried or aboveground tank as well as in a mobile tank truck. The Lev'O Sensor reports the data used to evaluate the level of filling on a public or private LoRaWANTM radio network. The sensor is delivered with a 10 meter cable and probe made of stainless steel.
