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 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.
A Coriolis flowmeter assembly having a continuous length of flow tube with dual loops, an inlet adapted to receive a flow of material from a connected pipeline and an outlet adapted to return said flow of material to said pipeline and a housing enclosing said dual loops, said flowmeter assembly comprising:
A Coriolis flowmeter assembly having a continuous length of flow tube with a first loop in a first plane and a second loop in a second plane, an inlet adapted to receive a flow of material from a connected pipeline and an outlet adapted to return said flow of material to said pipeline, a driver affixed to said first loop and said second loop to oscillate said first loop and said second loop in opposing direction, pick-off sensors affixed to said first loop and said second loop to measure said oscillation of said flow tube and a housing enclosing said first loop and said second loop, said flowmeter assembly comprising:
