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: Monitoring a mass flowmeter includes ascertaining a resonant frequency of a bending oscillation, wanted mode, and a density measured value of a medium as a function of the frequency. A bending oscillation is excited outside of resonance with an excitation signal having an amplitude and a frequency (? times the resonant frequency of the bending oscillation, wanted mode). An amplitude of a sensor signal of the bending oscillation outside of resonance is ascertained. A value of an integrity function of the measuring tube depending on a ratio of the sensor signal amplitude to the excitation signal amplitude of the bending oscillation is ascertained. The integrity function depends further on a density term of a transfer function that models contributions of a plurality of oscillation modes to the sensor signal. This function is reduced to reference conditions, and/or transformed to an integrity value, which has no cross sensitivities for media density.
