An online vapor pressure analyzer that determines continuously and not in batch mode, the vapor pressure of a sidestream sample composed of a single compound liquid having a single vapor pressure or a mixture of liquid compounds having different vapor pressures. It determines the highest pressure of the liquid in a given temperature at which the lightest component starts to flash, such pressure being the vapor pressure of the liquid at that temperature. The sidestream sample is pass through the analyzer and then returned to the process line. The analyzer is comprised of an upstream aeration or density measurement means, a pressure reducing means such as capillary tubing to reduce the pressure to the vapor pressure of the liquid without creating pressure recovery and promote flashing at the true vapor pressure by fluid shear, a downstream aeration or density measurement means, and instrumentation means to detect vapor pressure, temperature and minimum aeration or density change that signifies flashing of the lightest component at the vapor pressure of the liquid. A flow regulator controls amount of sample admitted and therefore controls the pressure drop across the capillary tubing. A pumps returns the sample to the process line.

A Coriolis mass flow meter that measures total mass flow of multi phase fluid mixtures of gases and liquids in any proportion even with slippage occurring among the various phases. The device includes a rotating member made up of a plurality of flow conduits arranged symmetrically around a shaft and driven by an electric motor or internal combustion engine. The conduits are attached on both ends to the shaft with one end closer to the shaft centerline than the other end. The passage of the multiphase fluid from the end of the conduit closer to the shaft and exiting at the end further from the shaft while being rotated causes centrifugal force to be imparted to the fluid separating the gas and liquid inside the conduits into distinct layers. At the same time, Coriolis force is generated as the fluid mixture flows through the conduit with an increasing rotational radius. The Coriolis force is imparted to the conduits where bending beam load cells are attached to measure the force.
