METHOD AND APPARATUS FOR MEASURING MASS FLOW RATE OF INDIVIDUAL COMPONENTS OF TWO-PHASE GAS-LIQUID MEDIUM Abstract of the Disclosure A method for measuring mass flow rate of individual com- ponents of two-phase medium comprises feeding a flow of a me- dium to be measured through a hollow pendulum, imparting un- damped oscillations to the pendulum, measuring energy requir- ed to maintain a constant oscillation velocity, the mass flow of the medium being assumed proportional to the measured ene- rgy value and the average density of the medium being assum- ed 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 flow rate of individual components of two-phase medium comprises a sealed housing accommodating a hollow pendulum supported therein. The housing mounts and 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 mass flow rate of two-phase medium and to the density of the two-phase medium being measured. The apparatus for carrying out the method for measuring mass flow rate of individual components of two-phase gas- - 2 - -liquid medium according to the invention provides for mea- suring mass flow rate of individual components of a two- -phase medium without recurrence to additional separation of the flow thus facilitating the measurements and making them more reliable.
