ABSTRACT:
A method for measuring the mass flow rate of individual components of a two-phase medium comprises feeding a flow of a medium to be measured through a hollow pendulum, imparting undamped oscillations to the pendulum, measuring energy required to maintain a constant oscillation velocity, the mass flow of the medium being assumed proportional to the measured energy value and the average density of the medium being assumed proportional to the measured fundamental frequency of the pendulum, and determining mass flow of each component from mathematical relationships.
An apparatus for carrying out the method for measuring mass the flow rate of individual components of a two-phase medium comprises a sealed housing accommodating a hollow pendulum supported therein. The housing mounts an electromagnetic coil for imparting undamped oscillations to the pendulum and an electromagnetic coil for converting oscillation velocity. Output frequency signals of converters are proportional to the mass flow rate of the two-phase medium and to the density of the two-phase medium being measured.
