Rota Meter a device used for measuring the volumetric flow of fluids such as water. It measures the rate of flow by varying the cross sectional area through which fluids flow and through this process cause a measuring effect.

It’s made from various materials like Plastic , glass or metal with a float in the tube , this float moves in linear fashion to the fluid flow rate .Rotameters are one of the most widely-used types of flow meters in the Industrial RO Segment.
