Program product to measure density, specific gravity, and flow rate of fluids |
摘要 |
Program product to measure fluid flow characteristics in a pipeline is provided. A vortex-shedding body is positioned within the pipeline to form vortices. A vortex meter can include a vortex frequency sensor to measure the frequency of the vortices to determine the volumetric flow rate. A differential pressure meter positioned adjacent the vortex-shedding body can produce a differential pressure meter flow rate signal indicative of the density of fluid when flowing through the pipeline. A thermal flow meter positioned adjacent the vortex-shedding body can produce a mass flow rate signal indicative of the mass flow rate of fluid when flowing through the pipeline. The program product can include instructions for a fluid characteristic determiner to perform the operations of processing measured and sensed signals to produce an output of a volumetric flow rate, a flowing fluid density, and a mass flow rate to be displayed on a fluid characteristic display.
