Abstract
A thermoelectric level detector employs an impedance element, at least a portion of which is meandering in configuration in which the resistive path repeatedly traverses the axis thereof, to detect the level of liquid in a tank. The impedance of the element depends on temperature and provides a measure of the liquid level. The pitch of the meander is relatively small in the reserve region of the tank to provide fine resolution in this region.
