Dakota Rotameters
Rotameters, also known as variable area flow meters, are ideal for measuring the flow rates of a variety of liquid and gas applications. These popular, practical units consist of a tube, float, linear scale, long measurement range, and low pressure drop. Models are economical, reliable, simple to maintain, and easy to install. They can withstand corrosive fluids as well as high temperatures and pressures. Rotameters can be calibrated for most gases or liquids. Acrylic, polysulfone, and encased glass-tubed models are available.
