Abstract:
A Coriolis flowmeter comprising:flow tube means adapted to receive a material flow from a flowmeter inlet and to extend said material flow through said flow tube means to a flowmeter outlet; a driver for vibrating said flow tube means; pick off means coupled to said flow tube means for generating output signals representing Coriolis deflections of said vibrating flow tube means with material flow; means responsive to said output signals generated by said pick off means for generating output information pertaining to said material flow; and characterized by the flow tube means being formed of plastic to define a plastic wetted material flow path that extends through the entirety of the length of said flow tube means; said wetted material flow path further includes plastic flow tube stubs each having a first end connected to ends of said flow tube means; a first one of said plastic flow tube stubs has a second end adapted to receive said material flow; a second one of said plastic flow tube stubs has a second end adapted to discharge said material flow.
