What is rotameter?
Rotameters are the most commonly used variable space move meters. It’s also often called rotor circulate meter or float move meter. Its operation is easy, with a liquid or gas passing via a conical tube. In order for this gas to cross via the tube, it should first raise a float that’s mounted contained in the tube.
What is working principle of rotameter?
When a rotameter is used with a liquid, the float rises as a outcome of combination of the rate head of the fluid and the buoyancy of the liquid.
With gases, the buoyancy force is negligible and the float moves largely due to the velocity strain head of the gasoline. In each cases, the higher the circulate rate, the upper the float moves up the tube. The float strikes up and down the tapered tube in proportion to the flow fee and the annular area between the float and the tapered tube wall. As the float moves up via the tube because of its tapered nature, the annular opening will increase. As this will increase, the differential pressure across the float decreases. When the load of the float is balanced towards the upward pressure exerted by the fluid or gasoline, the float stabilizes.
The float can then be compared to a calibration scale printed on the tube itself or placed subsequent to the tube on the surface of the meter. The calibrated scale will typically give a volumetric flow reading, corresponding to liters per minute (LPM).
Application of rotameter
Rotameters are generally used to measure the move of liquids or gases, with the following application examples:
Laboratory.
Testing and production lines.
Processing business.
Oil industry.
Oxygen move measurement in medical applications.
For metering purge circulate (i.e. viscous fluids with suspended particles).

What is working principle of rotameter?
When a rotameter is used with a liquid, the float rises as a result of combination of the speed head of the fluid and the buoyancy of the liquid.
With gases, the buoyancy pressure is negligible and the float moves mostly as a end result of velocity strain head of the gasoline. In both cases, the higher the move fee, the higher the float strikes up the tube. The float strikes up and down the tapered tube in proportion to the circulate fee and the annular area between the float and the tapered tube wall. As the float moves up by method of the tube because of its tapered nature, the annular opening increases. As this will increase, the differential stress throughout the float decreases. When the load of the float is balanced towards the upward drive exerted by the fluid or gas, the float stabilizes.
