Abstract

A flow meter (500) is disclosed that is comprised of a base (552), a driver (D), pick-offs (LPO, RPO), and a flow tube (501) made from a fluoropolymer substance. The base of the flow meter is comprised of a first leg (517) and a second leg (518). The first leg includes a tube opening (502) and an adhesive opening (504) and the second leg includes a tube opening (512) and an adhesive opening (514). 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 (506) 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 (508) of the tube opening to affix the flow tube to the base. The adhesive opening in the second leg performs the same function.

Description

technical field [0001] This invention relates to flow meters, and more particularly to the manufacture of flow meters including flow tubes formed from fluoropolymer materials. Background technique [0002] The use of Coriolis effect mass flow meters to measure mass flow and other information about materials flowing through pipelines is known, as in U.S. Patent 4,491,025, J.E. Smith et al., Jan. 1, 1985 and Feb. 11, 1982. Re.31450 of J.E.Smith. These flowmeters have one or several flow tubes that are not straight, curved or irregularly configured. Each flow tube has a set of natural modes of vibration which can be simple bending, torsional or twisting. Each material-filled flow tube is driven so as to resonate in one of these natural modes. The natural mode of vibration is determined in part by the combined mass of the flow tube and the material within the flow tube. The flow meter does not have to be driven in native mode, if desired. [0003] Material flows into the fl...
