Abstract
A method () of determining a vibration response parameter of a vibratory element () is provided. The method () includes vibrating the vibratory element () at a first frequency with a first drive signal, receiving a first vibration signal from the vibratory element () vibrated at the first frequency, measuring a first phase difference, the first phase difference being a phase difference between the first drive signal and the first vibration signal. The method () also includes vibrating the vibratory element () at a second frequency with a second drive signal, receiving a second vibration signal from the vibratory element () vibrated at the second frequency, measuring a second phase difference, the second phase difference being a phase difference between the second drive signal and the second vibration signal. The method () further includes using the first phase difference and the second phase difference to determine at least one of a phase difference, and a frequency of the vibratory element ().
