Abstract

An apparatus is proposed for volumetric metering and filling of liquids which includes a vertically extending dispensing chamber provided with a lower inflow and outflow opening and an upper vent opening. A float having an indicator ring is freely reciprocable in the dispensing chamber and scanning elements for controlling the inflow or outflow of liquid are disposed outside the dispensing chamber. Further control elements control a retarded inflow or outflow of the liquid via a throttle device, so that the upper and lower height, the criterion for accurate metering out of quantities of liquid, of the surface of the liquid in the dispensing chamber can be regulated.
