A rotameter is a type of flowmeter that measures the flow rate of fluid in a closed tube. It consists of a float that is free to move up and down in the tube, and a graduation scale that is external to the tube. As the fluid flows through the tube, the float is pushed up by the fluid's flow. The higher the float moves, the greater the flow rate. The rotameter's graduation scale is used to determine the flow rate.
A flowmeter, on the other hand, is a device that measures the flow rate of fluid in an open pipe. There are many different types of flowmeters, but they all work on the principle of flowing a known volume of fluid through the meter and measuring the time it takes to do so. The flow rate is then calculated based on the time it took to flow the known volume.

What is the difference between a rotameter and a flow meter?
Flow meters measure the flow or movement of a substance through a pipe or other closed system, while rotameters measure the rotation of a object in a fluid. Both types of devices have their advantages and disadvantages, but flow meters are generally more accurate and precise than rotameters.
Frequently Asked Questions
How does A rotameter measure flow rate?
A rotameter measures flow rate by reading a scale on the tube or next to the tube.
What are the advantages of A rotameter?
A rotameter is a very accurate way to measure flow rate. It doesn't rely on external power or fuel, so it is portable and can be used in a variety of situations. The inherent properties of fluids allow for a relatively simple rotameter design, which makes them mass-produced cheaply.
How does a mechanical flow meter work?
A mechanical flow meter is a precision instrument used in the chemical and oil industries to measure fluid or gas volumetric flow rates. In typical use, adevice rests on an inclined scale and measures the distance that a floating weight (called a 'float') moves up or down the scale under the action of moving fluid. The position of the float can be transmitted to an external indicator by means of a magnetic coupling.
What is a direct reading flowmeter?
A direct reading flowmeter measures flow by the displacement and flow around a weighted float within a conical tubular column graduated for flow rate. The greater the flow the higher the float travels upward in the graduated column.
How do you determine the flow rate of A rotameter?
1.Measure the float height. 2. Determine full flow capacity of the meter with calibrated floats by matching float height to that of calibrated scale on the outside of the meter. 3. Calculate the required flow rate while keeping float position constant as per calibration table.
