Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly to the flowrate of the fluid in that tube. OMEGA ™ laboratory rotameters are far more versatile due to the use they make of correlation equations.
