Measuring principle
The measuring principle is comparable to that of a slider potentiometer, with in this case the liquid representing the slider pick-off.
An alternating current is applied to a stainless steel tube to cause a drop in voltage via the electrical resistance of the tube (cf. slider path). The conductive wall of the vessel forwards the tapped voltage conducted through the liquid to a high-resistance amplifier. Based on the supply voltage, this yields the ratio between the depth of immersion and the total length of the tube.
Together with the high-resistance pick-off, this ratio explains why the measuring system is independent of the conductivity of the product. Sticky deposits merely form a parallel connection with the anyway very low-resistance tube. What is measured, therefore, is only the actual product between tube and vessel wall.
