Where would you read the oxygen flow rate on a vane bobbin?

Explanation:
The flow rate is read at the top of the vane bobbin. This float rises in a tapered flowmeter tube as oxygen flows, and the scale is calibrated so the value lines up with the top edge of the bobbin. Reading the top gives the actual flow because that position corresponds to where the float is stopped by the tube’s constriction and the calibrated scale. Reading from the bottom or sides wouldn’t reflect the true flow, and the left/right positions have no relation to the measurement. For accuracy, view at eye level so the top of the bobbin aligns with the scale.
