You could say “Knock and listen” but it’s more sophisticated than that. The sensor technology is built on a method of monitoring local, mechanical properties of a fluid tank. The sensor exerts force onto a tank wall and causes it to vibrate. An accelerometer is part of the sensor and it measures the vibrations caused by the force and transmits the signal to the sensor processor. The processor’s algorithm calculates a vibration value each time the sensor performs a measurement.
