  • Method for manufacturing a Coriolis flow meter assembly
    Patent number: 6374478
    Abstract: A system for manufacturing a straight tube Coriolis Flowmeter. The system of this invention provides a process for connecting a flow tube assembly including a balance bar and a flow tube to at least two points inside a casing.
