Abstract:
1. Coriolis mass flow sensor for measuring a fluid flowing through a pipe, said sensor comprising: a first tube for conducting the fluid to be measured, said first tube having a single substantially V-shaped tube segment with an inlet-side straight tube portion and an outlet-side straight tube portion, said straight tube portions being in connection via a vertex bend portion of said first tube segment, said V-shaped tube segment being coupled to the pipe during operation; a second tube having a single substantially V-shaped tube segment with an inlet-side straight portion and an outlet-side straight portion, said straight portions being in connection via a vertex bend portion of said second tube segment; wherein said first and said second tubes are coupled mechanically with each other at an inlet-side location and an outlet-side location, respectively; an excitation arrangement coupled to said first and said second tubes for vibrating said first and said second tubes; and a sensor arrangement coupled to said first and said second tubes for detecting inlet-side and outlet-side vibrations of at least one of the tubes.
