Abstract: A method of manufacturing a Coriolis flowmeter for the measurement of a process material requiring an ultra high level of purity. This is achieved by forming the entire flow path of the Coriolis flow meter from a PFA plastic material that does not transfer ions from the Coriolis flowmeter to the process material flowing through the flowmeter.

Abstract: A flow meter is disclosed that is comprised of a base, a driver, pick-offs, and a flow tube made from a fluoropolymer substance. The base of the flow meter is comprised of a first leg and a second leg. The first leg includes a tube opening and an adhesive opening and the second leg includes a tube opening and an adhesive opening. The flow tube passes through the tube openings of the first leg and the second leg. The tube opening of the first leg has a diameter slightly larger than the flow tube to create a gap between the tube opening and the flow tube. The adhesive opening of the first leg provides access to the gap so that adhesive may be applied to the flow tube and an inner surface of the tube opening to affix the flow tube to the base. The adhesive opening in the second leg performs the same function.

Abstract: A flow meter pickoff assembly for nulling a flow meter zero offset is provided. The flow meter pickoff assembly includes a mounting device affixed to a first flow meter portion of a flow meter and a first pickoff sensor half adjustably affixed to the mounting device and configured to interact with a second pickoff sensor half affixed to a second flow meter portion. At least one relative angle of the first pickoff sensor half in relation to the second pickoff sensor half can be adjusted by adjusting the first pickoff sensor half to the mounting device according to at least one adjustment axis. The flow meter pickoff assembly further includes an adjustment means for enabling the first pickoff sensor half to adjust with respect to the mounting device along the at least one adjustment axis in order to adjust the at least one relative angle.

Abstract: A drive system for use in a temperature environment. The drive system is made of materials that can withstand high temperatures without degrading. There are no plastics or epoxy adhesives used in this drive system. The drive system is also made more efficient by placing the drive system on a flow tube outside of a loop in the flow tube between the inlet and the outlet.
