Implementation of liquid Level sensing

As mentioned earlier, point level measurement uses one or more sensors placed at discreet levels on the tank based upon the application’s need to know the liquid level. The system uses the on/off state of the various sensors to deduce the liquid level. For example, Figure 6 shows a tank and PCB with one sensor attached to it at the end for tank empty detection.
