Online Air Rotameter

A sort of flow measurement tool used to gauge the flow rate of air or gas is the air rotameter. It is made up of a scale, a float, and a tapered tube or float tube.

An air rotameter's operation is dependent on the float's buoyancy in the moving gas or air. The bottom of the tapered tube is wider than the top, which gradually gets smaller. The float, which is often a sphere or cylindrical item, is positioned inside the tube and moves vertically depending on how much air or gas is flowing through it at any given time.

The float experiences force from the air or gas flowing through the rotameter, which causes it to rise. The flow rate is determined by the location of the float inside the tapered tube. When the buoyancy force on the float equals the gravitational force pressing on it, the float is in a stable position.

After then, the float position is measured against a scale that is next to the rotameter. In order to measure flow rate directly, the scale is often calibrated in volumetric flow units such cubic feet per minute (CFM) or litres per minute (LPM).

In several applications where the measurement of air or gas flow rates is required, air rotameters are frequently utilised. They are frequently used in fields including laboratory apparatus, industrial processes, compressed air systems, and HVAC systems.

It's significant to remember that the calibration of an air rotameter depends on the gas being measured as well as the usage circumstances. In order to achieve accurate flow rate readings, it is advised to follow the manufacturer's instructions and guidelines for correct installation, calibration, and usage of an air rotameter.
