Introduction to Glass Rotameters

Glass rotameters are a type of variable area flowmeter used to measure the flow rate of liquids and gases. They operate on the principle that the fluid flow raises a float in a tapered tube, and the position of the float is proportional to the flow rate. The clear glass construction allows for direct visual observation of the float position, making them a popular choice in various industries such as chemical processing, pharmaceuticals, food and beverage, and water treatment. These devices are known for their simplicity, reliability, and relatively low cost.
