What is a rotameter?
The rotameter measures the flow of liquids or gases in industrial use. The basic rotameter design includes a vertical tube of the gradually increasing diameter made of glass or other transparent material in which the float rises and decreases according to the flow of liquid or gas. The float rises when the flow is high because it is forced to look for a larger diameter between themselves and the outer side of the tube to suit the strength of the flow. When the flow is lower, gravity allows the float to find a balance that can be adapted to the internal linear reading scale. When the float rises and falls, it turns on its axis, leading to the name of the rotameter. Reading from the inner linear scale is removed from the center of the float shape or from the top of the float according to the instructions in the device manual. Sometimes the float is clearly colored, so watching can easily determine whether it is stuck or spins freely. Although it is called a float, it does not actually call for liquid. Instead it is designed to use the scientific principle known as the PrinceThe variable area that allows the float to find a balance between the ascending pressure of the liquid or the gas and the gravitational pull down.
When the flow changes, the float either ascends or falls in response and then settles with a new speed balance of versus gravity. The linear scale inside shows in most rotameters a range of 0% to 100%. Conversion charts for different types of liquids or gases can be used to determine the correct reading for a particular liquid or gas. However, some rotameters are designed to provide digital read and temperature reading. Others use a needle valve, not only to subtract the flow but also the Reading flow at different pressures.
The basic construction of rotameters, whether made of glass, plastic or metal, does not require any external energy source, but works according to basic physical laws. As long as the rotameter is maintained firmly vertical, it provides good valuesAnd can be used in many different applications. They can be used in liquid and gases and can be equipped with high and low limitations. These devices also use research departments in several types of processing industries. The rotameter can also be used as a flow meter for cleaning for constant lubricants to the bearing to reduce the downtime in production.
