In a metering unit () having at least one outlet () for dispensing an aerosol with a defined concentration, with at least one inlet () for a carrier gas, at least one inlet for a liquid, preferably for a hydrogen peroxide solution, and a buffer container () for the liquid, it is provided that the metering unit () has at least one liquid flow controller () on the outflow side.

Metering unit

A modularly structured unit is comprised of a flow resistance element and an orifice plate adjacent thereto, preferably for use in the main flow duct of a thermal mass flow rate measuring or control device. The flow resistance element can be combined with various orifice plates having different opening diameters.

The device for metering fluid mixtures, in particular liquids containing a gas such as carbon dioxide, includes a flow sensor, a metering valve, and a controller that drives the metering valve as a function of a set point and of the flow rate measured. The flow sensor has an impeller wheel having a horizontal axis, the fluid mixture being guided on an arcuate path on the periphery of the impeller wheel, the path being directed from bottom to top. Despite the presence of gas, a precise metering is achieved.

To provide conditioned fluid flows, a base body has a main flow duct formed therein with a bypass duct that is branched off from and led back to the main flow duct. An exchangeable flow conditioning insert includes a flow resistance element and is adapted to be arranged in the main flow duct relative to the bypass duct in an axial installation position such that the flow resistance element generates a pressure difference between ports of the bypass duct at the main flow duct.
