Abstract:
A Coriolis-type mass flowmeter which comprises:a flowtube through which a fluid to be measured is permitted to flow, the flowtube comprising first and second ends; a counterbalance beam which is coupled to the flowtube proximate the first and second ends; means for vibrating the flowtube and the counterbalance beam in opposition to one another; at least one pair of inertial masses, each of which is movably coupled to the counterbalance beam; and means for selectively positioning the inertial masses longitudinally along the counterbalance beam; wherein the frequency response of the counterbalance beam can be selectively altered by appropriately positioning the inertial masses along the counterbalance beam to thereby achieve a desired condition of balance between the counterbalance beam and the flowtube.
