摘要： A method for operating a Coriolis mass flowmeter includes: calculating error-free oscillation signal phase differences using a first measuring channel pair with a first measuring channel phase difference; calculating averaged error-containing oscillation signal phase differences using a second measuring channel pair with a second measuring channel phase difference; determining error-containing oscillation signal phase differences using a third measuring channel pair with negligible measuring channel phase difference; determining the second measuring channel phase difference by difference formation from the averaged error-containing oscillation signal phase differences of the second measuring channel pair and the error-free oscillation signal phase differences of the first measuring channel pair; obtaining error-free oscillation signal phase differences by subtracting the determined second measuring channel phase difference from the error-containing oscillation signal phase differences of the third measuring channel pair; and using the error-free oscillation signal phase differences for determining the mass flow rate.

摘要： Method for operating a resonant measurement system, especially a Coriolis mass flow meter, so as to be excitable in a linear operating range, the driving terminal current triggered by an electric excitation signal and the driving terminal voltage of the electromagnetic drive triggered by the electric excitation signal are measured. The driving power is determined from the driving terminal current and the driving terminal voltage, and if the driving terminal current exceeds a given maximum driving terminal current, and/or if the driving terminal voltage exceeds a given maximum driving terminal voltage and/or if the driving power exceeds a given maximum driving power, the electric excitation signal is limited to a threshold value such that the driving terminal current remains below the given maximum driving terminal current, and/or the driving terminal voltage remains below the given maximum driving terminal voltage, and/or the driving power remains below the maximum driving power.

摘要： A method for operating a resonant measurement system has at least one: adjustment device, electric actuation device, electromagnetic vibration generator, vibrating element, and vibration recorder. The adjustment device generates an output signal to trigger the electric actuation device, the electric actuation device provides an electric excitation signal to the electromagnetic drive, the electromagnetic drive excites the vibrating element to the same vibration in at least one normal mode, and the excited vibration is sensed by the vibration recorder and is output as an output signal. To approach, maintain and readjust a resonant point as an operating point of the resonant measurement system, the phase difference between the output signal of the vibration recorder and the adjustment device output signal is acquired, an adjustment deviation is calculated from a predefined phase difference and the acquired phase difference, and the adjustment deviation provided to the adjustment device as an input signal.

摘要： A method for operating a Coriolis mass flowmeter that has at least one measuring tube with medium flowing through it involves exciting the measuring tube excited to oscillation, detecting the oscillations of the measuring tube and determining the density of the medium. Detection of the state and a change in the state of a Coriolis mass flowmeter is achieved by determining a calibration temperature and a calibration density sensitivity of the Coriolis mass flowmeter using the detected oscillations, at a temperature differing from the calibration temperature, and a density sensitivity of the flowmeter determined using the detected oscillations. A measurement rate of change of the density sensitivity is determined and a forecast rate of change of the density sensitivity is calculated using a forecast algorithm, and at a given deviation of the measurement rate of change from the forecast rate of change rp, a deviation signal is generated.
