Fuel-Water Level lorawan Sensor (ultrasonic)

The level measuring sensor, for fuel tanks, water or any other liquid tank, based on an ultrasonic measurement, running on battery up to 14 years.


The water level or fuel level sensor is particularly suitable for outdoor or underground tanks. It allows the measurement of the liquid level, between the top of the tank and the level of water or fuel. The measurement is ultrasonic, and can raise a height between 12 cm and 4 meter. It is therefore easy to measure the volume of fuel, water or any other liquid present in a tank.

The water level or fuel level sensor allows the configuration of 3 thresholds to be notified of a level that has become too low or too high. It allows the configuration of the measurement frequency, and the frequency of data transmission through a LORAWAN network.
This water level or fuel level sensor is autonomous. Its battery allows it to operate up to 14 years, by measuring the level four times a day, and by relaying information through the LORAWAN network.

Mounting the sensor on the tank is simple. Just screw it. By default, the water / fuel level sensor supports a standard 2 inch attachment tip. A multidimensional adapter is available as well. Like ultrasonic measurement in the form of a cone (30 degrees), it is also possible to place a waveguide, when the level sensor is placed too close to a wall.

About LoRaWAN

The LoRa network, also called LoRaWAN, is a dedicated Data network for IOT sensors. It provides small data transmission on large distances – up to 15 km, while consuming very limited energy, allowing sensors to be operated on small batteries.


  • In Belgium and Luxembourg, Proximus operates a nation wide LoRaWAN network.
  • In France, Orange and Bouygues operate a LoRaWAN network.
  • In the Netherlands, KPN is the main LoRaWAN operator.
  • In Switzerland, SwissCom is the main LORAWAN operator
  • LoRaWAN is available in most Countries (Spain, Andorra, Italy, Bulgaria, Czech Republic, UK, Ireland, Iceland...). Worldwide.

If there is no LoRaWAN coverage in your country/region, it is also possible to deploy a private LoRaWAN network.

Contact us if you have questions about the LORAWAN coverage in your region.
