ABSTRACT:
A device for monitoring dripping of a fluid from a fluid channel, the device comprises a capacitor, being formed on or integrated with the fluid channel, and electrical contacts, connecting the capacitor to a capacitance measuring device, the capacitor is designed and constructed so that a change in a capacitance thereof represents a formation of a drop near an edge of the fluid channel.
