Abstract
A method for increasing stability of a Coriolis mass flow meter by relieving residual and internal stress within the flow tube and related structures of the meter. The method including the steps of bending the flow tube in the desired form, fixing related flow tube structures onto the flow tube, clamping the flow tube so as to maintain the desired form during subsequent processes, annealing the flow tube, and cryogenically cooling the flow tube. An apparatus to be utilized along with the method of the present invention fixes the flow tube during the annealing and cryogenic cooling treatment processes to maintain the desired shape of the flow tube. The invention also contemplates the flow tube made in accordance with the method of the present invention.
