Abstract:
1. An apparatus for sequentially measuring a quantity of liquid in each of a plurality of containers, comprising: at least one capacitive measuring cell having a measuring section, a first capacitive guard section preceding the measuring section and a second capacitive guard section following the measuring section, the first and second capacitive guard sections having electrodes positioned to regularize field lines in said measuring section, and the measuring section having a first plurality of electrodes positioned on a first side of the measuring section and a second plurality of electrodes positioned on a second side of the measuring section opposite the first side; and a conveying system for feeding each of the plurality of containers along a path through the at least one capacitive measuring cell, wherein the measuring section of the at least one capacitive measuring cell measures mutual capacitances between pairs of electrodes containing one electrode from each of the first and the second plurality of electrodes of the measuring section to obtain information concerning the height of the liquid in each of the plurality of containers by which to determine the quantity of the liquid therein.
