  • Coriolis mass flow meter, vibrating tube density meter and vibrating sheet used therein
    Patent number: 9360358
    Abstract: The present invention relates to a Coriolis mass flow meter, a vibrating tube density meter and a vibrating sheet used therein, and more particularly, to a vibrating sheet for use in a Coriolis mass flow meter or a vibrating tube density meter, the vibrating sheet having at least one welded connecting portion that is fixedly welded to the flow tube of the Coriolis mass flow meter or the vibrating tube density meter, the flow tube being excited to vibrate around a revolving axis at the welded junction of the vibrating sheet and the flow tube. The welded connecting portions of the vibrating sheet are only formed in the stress insensitive region of the vibrating sheet, wherein the stress insensitive region is the region of the vibrating sheet which has an angle of not more than 45 degrees with respect to the revolving axis. In addition, the present invention also provides a Coriolis mass flow meter and a vibrating tube density meter using the vibrating sheet.
