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, it causes the float to rise. The position of the float within the tube is directly related to the flow rate of the fluid. Glass rotameters are widely used in various industries such as chemical, pharmaceutical, food and beverage, and environmental monitoring due to their simplicity, low cost, and visual readability. They can provide real - time flow rate information and are suitable for both small and medium - scale flow measurement applications.
