Why must gas orifice plate flow meters be installed from bottom to top?

Why doesn’t the gas work from bottom to top?
The gas should flow from top to bottom, didn’t you get it backwards? Measuring liquids is done from bottom to top. The reason for this is that, under any circumstances, it is necessary to ensure that the fluid flows evenly across the plane of the orifice plate. Only in this way can the calculation equations for orifice plates be used; otherwise, the results will be inaccurate.
I still don’t understand what is being said. Could you be more specific? I can’t quite make it clear
When measuring the flow rate of liquids, orifice plate flow meters should be installed in horizontal pipes (10 units in front and 5 units behind). For measuring the flow rate of gases, they should be installed in vertical pipes (10 units in front and 5 units behind). The flow direction of the medium can be from top to bottom, from bottom to top, or horizontally as well The impact isn’t significant; we have used several installation methods.
