Description

Fluid Pressure Sensor "Lev'O" LoRaWAN

The LEV'O SENSOR measures the level of tanks, cisterns and cavities, if the geometry is known, up to a depth of 4.5 m. It transmits the absolute water pressure of a liquid (water, fuel, oil, fertilizer, etc.), whether it is used in an underground or above-ground tank or in a mobile tanker. The Lev'O sensor delivers the data necessary to determine the level to a public or private LoRaWAN radio network. The probe is supplied with a cable length of 10 meters.
