Nitrogen setting for Argon regulator

[beardyoldcorpse]

Does anyone know the correct setting for an Argon regulator to give equivalent of 25 LPM of Nitrogen?

When using Nitrogen with an Argon flowmeter, Divide the Argon reading by 1.4 to get the true Nitrogen flow. So for 25 Lpm of Nitrogen you need a reading of 35lpm Argon: 35:1.4=25

Many thanks for your reply which confirms my research. Although it seems to be counter intuitive as from what I understand Argon is heavier than Nitrogen which you would think would make the lighter gas run through the regulator faster! However I m not the sharpest tool in the box!
