Abstract:
1. A method of manufacturing a Coriolis flowmeter adapted to extend a received process material flow having an ultra high level of purity free from contamination due to ion transfer from said Coriolis flow meter to said process material; said method comprising the steps of: coupling a flow tube means to a base, wherein said flow tube means is formed entirely from PTFE or PFA; affixing a driver to said flow tube means; coupling a pick-off means to said flow tube means; affixing inlet and outlet ends of said flow tube means to at least one process connection; and characterized in that said step of coupling said flow tube means to said base is proceeded by the step of etching said flow tube means to create a surface suitable for coupling and affixing flowmeter components.
