ESAB Linde L-32 Flowmeter is a device used to measure the flow rate of gases such as argon, helium, carbon dioxide, and nitrogen. It is typically used in welding and cutting applications. The flowmeter has a calibrated plastic square tube with four scales, each corresponding to one of the gases it can measure. The tube can be rotated to read the flow rate from any of the scales. The flowmeter is accurate to within 5% of the maximum calibrated scale reading for each gas. It is equipped with standard "B" size inert gas connections (5/8-in. 18 R.H.
