Rota Metar

A rotameter is a type of flow meter that can be used in an open or closed system to determine the flow rate of a fluid, usually a gas or liquid. It is made up of a tapering tube that has a ball or float inside of it. The float or ball rises as the fluid passes through the tube, displaying the flow rate on a scale that is marked on the tube. Rotameters are commonly used as an easy and affordable way to monitor flow in a variety of industries, including chemical processing, water treatment, pharmaceuticals, and HVAC systems.
