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.
