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