Abstract
A system and method for improved flow measurements for LCG, such as liquid petroleum gas (LPG), is disclosed. Embodiments of the present technology detect the presence of a vapor in a fluid flowing in a mass flow meter. A control valve is then adjusted to provide enough back pressure to prevent the measured liquid from flashing and to reduce the presence of vapor in the fluid flowing in the mass flow meter. By keeping the fluid in liquid form, the present technology reduces the vapor flowing in the mass flow meter, increasing the accuracy of mass flow and other measurements. Utilizing a similar principle of vapor detection, embodiments of the present technology provide for improved average parameter value calculation, such as average density calculations and equivalent liquid volume calculations.
