A Gas Flow Rotameter is a type of variable area flow meter used to measure the flow rate of gases. It consists of a vertically oriented tapered tube, usually made of acrylic or glass, and a float inside that rises or falls depending on the gas flow rate. The float’s position on a calibrated scale indicates the volumetric flow rate of the gas.

A Purge Acrylic Body Rotameter is a precision flow measuring device designed for low flow rate applications, commonly used for purging, sampling, or carrier gas measurement. Constructed with a clear, durable acrylic body, it provides excellent visibility of the float for easy reading. The rotameter operates based on the variable area principle, where a float rises in a tapered tube as flow increases.
