Rotameters are simple industrial flow meters that measure the flow rate of liquid or gas in a closed tube. It requires no external power or fuel & clear glass is used which is highly resistant to thermal shock and chemical action. Rotameters are popular because they have linear scales, a relatively large measurement range, low-pressure drop, and are simple to install and maintain.
