IN SITU TRANSDUCER CALIBRATION

A method for calibrating a flowmeter (5) transducer is provided comprising the steps of exciting a vibration mode of a flowmeter (5) flow tube (130, 130′) and ceasing to excite the vibration mode, wherein a free decay response of the flow tube (130, 130′) is measured. Amplitudes and phases of the fr...

Zusammenfassung:	A method for calibrating a flowmeter (5) transducer is provided comprising the steps of exciting a vibration mode of a flowmeter (5) flow tube (130, 130′) and ceasing to excite the vibration mode, wherein a free decay response of the flow tube (130, 130′) is measured. Amplitudes and phases of the free decay response at a drive frequency are extracted, and a strength of the transducer is calculated.
