1. What is a Metal Tube Rotameter?
Metal tube rotameters, also known as variable area flow meters, are instruments used to measure the flow rate of fluids in a system. They consist of a tapered metal tube and a float that rises and falls based on the flow rate. As the flow increases, the float rises to a position that corresponds to the flow rate, allowing for easy visual interpretation.
