This is the video of flow rate from the MIG nozzle. The gas tap is fully opened on the bottle, and the flow meter knob is fully open as well.
Something obviously not right with this picture. I am getting gas out of the MIG nozzle(consistent), but according to the flow meter(if it is accurate) I
am not getting enough flow.

Pardon me about the background noise from the rain, but you can still hear the hissing out of the nozzle, as well as the jumping ball inside the flow meter.
