Introduction to Glass Rotameters
Glass rotameters are flow measurement devices that operate on the variable area principle. They consist of a tapered glass tube with a float inside. As the fluid (liquid or gas) flows through the tube, the float rises to a position where the upward force exerted by the flowing fluid balances the gravitational force acting on the float. The position of the float indicates the flow rate of the fluid passing through the tube.
These devices are widely used in various industries such as chemical, pharmaceutical, food and beverage, water treatment, and many others due to their simplicity, low cost, and visual readability. They can measure a wide range of flow rates and are suitable for both clean and slightly dirty fluids.
