摘要
A Coriolis mass flow meter (300), a vibrating tube densimeter (300), and a vibrating sheet (320) used therein. Specifically, a vibrating sheet (320) used in a Coriolis mass flow meter (300) or a vibrating tube densimeter (300) is provided. The vibrating sheet (320) has at least one soldering connection portion fixed, through soldering, onto a flow tube (111, 112) of the Coriolis mass flow meter (300) or the vibrating tube densimeter (300), and the flow tube (111, 112) is excited to vibrate around the axis of rotation at a soldered junction of the vibrating sheet (320) and the flow tube. The soldering connection portion of the vibrating sheet (320) is merely formed within an area insensitive to the stress of the vibrating sheet (320). The area insensitive to the stress is an area on the vibrating sheet and forming the angle with the axis of rotation being less than or equal to 45°. In addition, the Coriolis mass flow meter (300) and the vibrating tube densimeter (300) using the vibrating sheet (320) are further provided. The present invention simplifies the process, and moreover improves the metering precision and service life of the Coriolis mass flow meter and the vibrating tube densimeter.
