Zusammenfassung
(EN)
A method for operating a flow meter is provided. The flow meter includes a driver and pickoff sensors coupled to a flow tube. The driver is adapted to vibrate the flow tube in response to a drive signal. The method comprises setting a target pickoff voltage and measuring a flow meter temperature. The method further comprises generating a temperature compensated target pickoff voltage and controlling the drive signal to maintain a temperature compensated flow tube amplitude.
