Abstract: A measuring apparatus for measuring a coating powder mass flow rate generable by compressed gas in a powder line includes a control and evaluation unit, which is configured and operable such that it can switch between an offset mode and an operating mode. In the offset mode, the control and evaluation unit ensures that a setting device applies compressed gas to the powder line and prevents the coating powder flow in the powder line, and that a pressure sensor then detects the pressure in the powder line. The control and evaluation unit interprets the detected pressure as an offset pressure value. In the operating mode, the control and evaluation unit ensures that the setting device enables the coating powder flow in the powder line, and then determines the coating powder mass flow rate flowing through the powder line on the basis of the pressure detected by the pressure sensor in the powder line, the offset pressure value and a correction value.

Abstract: A powder center for supplying a powder coating facility with coating powder includes a powder reservoir container and a powder conveyor for transporting powder out of the powder reservoir container in the direction of the powder coating facility. Moreover, the powder center includes a container lid that covers the powder reservoir container while powder is being conveyed and can be removed at least partly for the purpose of cleaning the powder reservoir container. Moreover, a cleaning unit for cleaning the powder reservoir container that can be moved from a parking position next to the powder reservoir container into a cleaning position inside the powder reservoir container by a manipulator is provided. Moreover, the powder center includes a controller by which the powder conveyor, the cleaning unit, and the manipulator can be controlled.
