The conventional and Out-of-Phase (OoP) liquid level sensing techniques are typically implemented for direct sensing or remote sensing applications. Sensors directly in contact with the liquid container maximize the performance of the system with minimizing sensor size, while remote sensing allows flexibility in system design. There are situations in which both of these sensor locations can exhibit false deviations in capacitance measurements from uncompensated environmental factors or the mechanical design does not allow direct/remote sensing. The immersive straw approach involves submerging the sensors directly in the liquid. The following application note describes the sensor design and compares the performance to direct and remote sensing applications.
