The process relates to the metering of liquid substances wherein the liquid substance, with separation of drops, is conducted through one or several discharge orifices, and the quantity of liquid is measured by way of the number of thus-produced drops. Liquid drops of varying sizes render exact metering impossible since no conclusion can be drawn to the exact quantity of liquid. According to the invention, drops of homogeneous density and constant size are produced by regulating the size of the drops by means of an electrical field generated in the zone of the discharge orifices. |
