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 and are adapted to be vibrated in phase opposition by a driver. The phase difference between the ends of the vibrating loops is measured. The measured phase difference is used to find the flow rate of the fluid. The flow tube is fixably attached to an anchor which is, in turn, attached to a housing. The anchor separates the vibrating dynamic portion of the flowmeter from the non-vibrating portion of the flowmeter.
