Variable Area/Rotameters Flow Meter and Switches
Variable area flow meters, commonly known as rotameters, operate on the principle of a float moving freely within a conical tube to balance the gravitational force and the force of the fluid flow. Designs with glass or plastic tubing allow for direct observation of the media flow. Rotameters are a popular choice for simple, yet accurate, flow measurement tasks. They are particularly suited for applications requiring low maintenance and easy-to-read measurements.
Rotameters are appreciated for their simplicity, reliability, and cost-effectiveness. They can measure flow rates of liquid or gas without requiring external power sources. The transparent tube provides a visual indication of the flow, which can be invaluable in applications where monitoring the condition of the flowing medium is essential. With a wide range of materials available for the float and tube, rotameters can be customized to suit various chemical compatibilities and temperature ranges.
