Is it significant if the atmospheric pressure entered for the orifice plate flow meter ordering location is incorrect?

As the title suggests, I realized that the value purchased earlier was incorrect – it should have been 82500 Pa, but it was entered as 98655 Pa. Will this have a significant impact on flow measurement?
It’s not that significant; orifice plates calculate flow rate based on the pressures before and after the throttling element, so atmospheric pressure doesn’t play a role

It does have an impact, as absolute pressure is used in the calculation of orifice plates; the extent of this impact depends on the pressure of the medium being measured – the higher the pressure, the smaller the impact, and the lower the pressure, the greater the impact.
