ABSTRACT:
A Coriolis mass flowmeter includes a housing which contains at least one measuring pipe, a supporting mechanism connected to both ends of the measuring pipe, a vibration generator which vibrates the measuring pipe, at least two sensors for detecting the vibration of the measuring pipe, an inlet conduit which introduces a fluid to be measured into the measuring pipe and an outlet conduit which discharges the fluid out of the measuring pipe. A Corioli vibration is applied to the measuring pipe which generates a Coriolis force in the fluid flowing in the measuring pipe. The Coriolis force is utilized for the measurement of the flow rate of the fluid. The Coriolis vibration has a frequency higher than the principal natural frequency of the supporting mechanism, i.e., in an inertial control region. The mass flowmeter is of a simple structure and lightweight, minimizes leakage of the energy of vibration to the outside, and has a high mechanical Q value.
