Variable area operating principle
Variable-area flow rate monitors, often referred to as rotameters, measure flow rate of a liquid or gas by relating linear displacement of an internal "float" or sharp-edged orifice plate (Lake Monitor) to a corresponding flow rate. The basis for our product provides accurate and repeatable flow rate measurements for both liquid and gases.
