Abstract
An apparatus for mixing a first liquid component with at least one additional liquid component. A fluid flow-through measuring device in the form of a gear pulser is connected to a supply line for a first component and generates a number of electrical pulses corresponding to the flow volume. A geared feed pump connected to the supply line for each additional component is driven by an electric stepping motor. A current supply circuit for each stepping motor operates to maintain an adjusted mixing ratio in response to pulses generated by said flowthrough measuring device.
