The Principle and Method of Density Difference Correction of Differential Pressure Flow Device
Differential pressure measurement device for flow is recommended to be horizontal,in actual,non-horizontal situation,brings difficulties and errors to the flow measurement.GB/T 2624 and PTC 19.5 have no discuss in this issue,The wrong formulas of ASME PTC6 brings misleading and confusion to users.Through the pressure analysis and formula derivation of the non-horizontal flow device,the formula and use suggestions are given to provide reference for relevant personnel.
