Validate the check box if you want to calculate the flow from the flow element dp. The code used is according to ISO 5267.
 Calculate the flow from the dp read on flow orifice. You will need to provide the details of your flow orifice

Flow element details

Location of the flow element At compressor suction At compressor discharge

Type of flow element Flow orifice, dp taken at flange Flow orifice, dp taken at D and D/2

Pipe diameter mm Inch

Flow element diameter mm Inch

Orifice dp readings mbar
This is the differential pressure across the flow element.
