| Help: | Density Ratio - used only when Standard or Normal Volumetric Flow Units are selected. You can either enter the density ratio directly here (density at process conditions divided by density at base conditions) or you can enter Fixed Process Temperature, Process Pressure, Process Compressibility, Base Temperature, Base Pressure and Base Compressibility and the vortex meter will calculate a density ratio based on the ideal gas law. If entered directly, the Process Pressure will be adjusted so that the ideal gas law equation results in the configured Density Ratio. |
