Abstract:
A grid sensor fox deterring a conductivity distribution in flowing media, comprising:electrodes in the form of one of electrically conductive grid bars and wires, which are disposed perpendicularly to a flow direction, in one of two and three planes, parallel to one another;a pulse generator;evaluation electronics;the electrodes of at least one of the planes being energized by the pulse generator and the electrodes of at least one other plane being coupled to the evaluation electronics for measurement of conductance based on current received by the at least one other plane from the at least one plane;holding devices for holding said electrodes; andan insulator for insulating the holding devices from the electrodes, wherein adjacent respective ones of said planes have the electrodes disposed at an angle substantially equal to 90.degree. with respect to the eltodes of the adjacent ones of said planes.
