ABSTRACT:
An apparatus for measuring the flow rate of a fluid flowing through a minimal flow pipeline with a Coriolis effect mass flowmeter. The flowmeter has a single flow tube with two loops. The loops are connected by a cross-over section. A driver oscillates the loops and the phase difference between the ends of the loops is measured. The measured phase difference is then used to find the flow rate of the fluid. The flow tube is fixedly attached to an anchor which is, in turn, attached to a housing. The anchor separate the vibrating, dynamic portion of the flowmeter from the non-vibrating portion of the flowmeter.
