A rotameter is an example of a variable area meter, where a weighted "float" rises in a tapered tube as the flow rate increases; the float stops rising when area between float and tube is large enough that the weight of the float is balanced by the drag of fluid flow. A kind of rotameter used for medical gases is the Thorpe tube flowmeter ...

A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. [ 1 ] It belongs to a class of meters called variable-area flowmeters , which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.
A Thorpe tube flowmeter, a type of variable-area flowmeter, or a rotameter, is an instrument used to directly measure the flow rate of a gas in medical instruments. It consists of a connection to a gas source, a needle valve opened and closed by turning an attached dial for control of flow rate, a float resting in a clear tapered tube, and an ...
NSWGR Rotameter. The New South Wales Government Railways constructed in 1903 a device for measuring the length of its lines of railway. That authority named the machine a Rotameter.

The more carbon dioxide that is added to the inert gas, such as argon, will increase penetration. The amount of carbon dioxide is often determined by what kind of transfer is used in GMAW. The most common is spray arc transfer, and the most commonly used gas mixture for spray arc transfer is 90% argon and 10% carbon dioxide.
