ABSTRACT:
This invention monitors the presence of or a flow of discrete small particles having a high dielectric constant, particularly seeds being planted by a seed planting machine. The invention uses the high dielectric constant of the particles, such as seeds, passing at least a pair of spaced electrodes to vary the capacitance between them and thereby indicate presence of the seed. The capacitance variation is detected and then processed by console located display, alarm and/or counting circuitry.
