Abstract: Methods and apparatus are disclosed utilizing a low-order parametric model for decoupling in conjunction with an optimization procedure to improve the ability to determine the density of the liquid phase of a bubbly mixtures within Coriolis meters by characterizing the effect of decoupling in the presence of bubble coalescence.
Abstract: A vibrating plate densitometer system and methods are disclosed that can provide information related to the density of a fluid in a vessel. Also disclosed are apparatus and methods to determine the speed of sound of the fluid and methods for designing such apparatus. Embodiments of the present disclosure include systems and methods to measure such parameters including the density, or the density and the entrained air, of wet concrete within a vessel. The present disclosure also provides means for maintaining accurate measurement that exploits the rotating nature of many vessels that contain concrete.
Abstract: A flow measuring device capable of measuring at least parameters of a multiphase flow and to quantify an effect of decoupling on an interpretation of the parameters based on at least one characteristic of the multiphase fluid is disclosed. The flow measuring system includes various augmentations and enhancements to a Coriolis meter. The flow measuring system is capable of determining decoupling parameters that can be used to improve the output of a Coriolis meter. A method of retrofitting a Coriolis meter is also disclosed.
