Dosing unit for fluids

摘要

A dosing unit for dosing fluids, comprises a membrane (12) with at least one opening (16) which acts as a resistance to the flowing medium, and a built-in pressure sensor (14) which picks up any pressure differences between the inlet and the outlet of the dosing unit. The membrane also incorporates a temp. sensor , a pressure transmitter and a setting device which allows the pressure to be adjusted, depending on the pressure differential and the temp.. Use - The arrangement is used for dosing fluids. Advantage - The arrangement is simple and allows exact quantities to be dosed.
