FLOW VELOCITY AND PRESSURE MEASUREMENT USING A VIBRATING CANTILEVER DEVICE

摘要

A method for determining the spring constant of a cantilever comprising positioning the cantilever in a fluid flow channel such that the cantilever extends parallel with the direction of fluid flow in the channel, causing fluid to flow in the channel, measuring the resonant frequency of the cantilever at one or more velocities of fluid flow and calculating the spring constant of the cantilever using the measured resonant frequency.
