Double Flowmeter Attachment
This dual flowmeter is designed to be attached to the 3/8" BSP connection on the outlet of a regulator which will then enable you to connect up two MIG welders or to use one cylinder for backing gas and welding simultaneously.
By adding flowmeters to your regulator your flow readings much more precise and can save you money over a standard gauge by just being more accurate at indicating the flow rate.
These flowmeters are designed to work with CO2, Argon and Argon mixes. Both have an adjustable needle valve which means you can control the flow and set to a rate that you desire.
