Flowmeter

[kurgan]

Is the gauge on the right the flowmeter?

 

[Romanticize]

yes, you have a pressure reductor and a flowmeter. Set the flowmeter on 15L per minute.

Thanks its an argon regulator I'm assuming it can be used on a nitrogen cylinder too?

 

[Romanticize]

yes but with two caveats:
- you have to make sure the connection (thread) is ok and tight
- due to density differences, the flowmeter will show different value (flow mismatch). If on argon regulator you put 10l/min, nitrogen real flow will be around 17l/min.

So instead of putting 15 Lpm, set it on 10-12 Lpm.

Noted, thank you

CAREFUL! I think you're wrong mate... I'm talking to Copilot about this, and he says something different:

Correction factor from argon to nitrogen

> 0.85

This means that if the flowmeter reads 15 L/min (calibrated for argon), the actual nitrogen flow will be: 15 × 0.85 = 12.75 L/min of nitrogen

How to adjust for 15 L/min of real nitrogen flow?

Divide the desired nitrogen flow by the correction factor:

> 15 ÷ 0.85 ≈ 17.6 L/min

So, you should set the flowmeter (calibrated for argon) to approximately 17.6 L/min to get a true nitrogen flow of 15 L/min.

PLEASE PEOPLE BE CAREFUL WITH THIS INFORMATION, MAKE SURE OF WHAT KIND OF REDUCTOR YOU ARE USING BEFORE TRYING TO FIND OUT HOW TO SET THE REGULATOR IN THE RIGHT FLOW... THE INFORMATION GIVEN HERE BEFORE MAY BE WRONG. MINE INCLUDED.
