Abstract
A system for calibrating a drive signal applied to a driver affixed to a conduit to cause the driver to apply a force that vibrates the conduit in a desired mode of vibration. The calibration is completed by first developing a mathematical model of the apparatus and then using the model to mathematically calculate a proper drive signal voltage. The development of a model of the dynamics and calculation of the drive signal voltage are completed by vibrating the conduit, measuring the vibrations of the conduit, detecting physical characteristics of the apparatus from the measured vibrations, and determining a drive signal that causes the driver to oscillate the conduit in a desired mode of vibration responsive to determining the physical characteristics of the apparatus.
