Pressure after Needle Valve and Rotameter
That is a good suggestion. Unfortunately I don't think I will be able to change the setup too much. This is what I was looking for. My initial thought was that I could count on the pressure being very close to atmospheric after the rotameter. I was a bit worried that I was missing something...- VCas

Pressure after Needle Valve and Rotameter
I understand that there is nothing I can do. My concern is regarding the flow measured by the rotameter. If the pressure after the needle valve is significantly higher than atmospheric, I would need to make a correction on the rotameter measurements (I want to know the mass flow rate of the...- VCas

Pressure after Needle Valve and Rotameter
Hello, I am currently evaluating the performance of a swirl burner. I got two lines going into the burner rig, (1) a methane line that comes from a pressurized cylinder and (2) a compressed air line. Each going through a needle valve and a rotameter. Currently there are no manometers after the...- VCas
