ESAB Linde L-32 Flowmeter accurately measures four different gases (argon, helium, carbon dioxide, and C-25 gas mixture) in cubic feet per hour (cfh). It connects to the latest manufactured inert gas or carbon dioxide regulators or to a pipeline using a suitable shut-off valve and a 1/4-in. NPT (male) x “B” inert gas (female) connection. The flow readings are accurate within ±5% of the maximum calibrated scale reading for each gas. The scale can be rotated to be read from any position. The flowmeter is equipped with standard “B” size inert gas connections (5/8-in.—18 R.H. threads).
