摘要

A metering system for metering a metering fluid includes at least one metering unit, a fluid supply component conveying the metering fluid to the metering unit, and a control module conveying a control fluid to the metering unit. The metering unit includes a first housing part, an exchangeable second housing part and a membrane which is arranged between the housing parts and divides a cavity formed between the housing parts into a pumping chamber and a metering chamber which are separated from each other in fluidic terms. Channels are formed in the first housing part which receive the control fluid and are in flow connection with the control module, and channels are formed in the second housing part which receive the metering fluid and are in flow connection with the fluid supply component.
