The paper presents the result of experimental and numerical study with an extended-throat venturimeter which is capable of measuring the flow rate of each phase gas-solid mixture. It was found that the different sensitivities of the differential pressure between the inlet and throat between the throat and diffuser are the major parameters to determine the loading ratio and the gas mass flow rate. The pressure drop, predicted by the conservative variable and source model, agree with the experimental data. The extended throat venturimeter shows promise as a device for metering the flow rate of each phase in a gas-solid mixture.
