RSA Instruments produces high-quality Glass Tube Rotameters, specifically designed for liquid and gas applications to measure flow rates. In this device, the float moves vertically within a tapered Borosilicate Glass Tube as the fluid flows upward from the bottom. The float stabilizes at a point where the buoyancy forces balance with its weight, corresponding to the flow rate. The scale on the tube then indicates the instantaneous flow rate based on the float's position.

Application:

- Ideal for measuring flow rates of water, liquids, gases, and air.
