The liquid level monitor AXsensor uses an acoustic pulse with low frequency and extremely low power consumption. The AXsensor is powered by batteries with a running time of 3-10 years. All electronics are outside the tank and the AXsensor transmits an acoustic pulse, through a measuring tube (waveguide) to the surface of the liquid, which measures the time calibrated for temperature. The AXsensor has a built-in antenna that communicates using the LoRa (LPWAN) and Sigfox network.
