Product Category : Rotameters
Accurate India offers Rotameter. Accurate India offers various types of stepper motor and drives proximity switch, photoelectric sensor, motion sensor, fiber optic sensor, color mark & label sensor, etc. The Rotameter is used to measure the flow rate of liquids and gases.
Salient features of Rotameter are:
It consists of a tube and float. The float response to flow rate changes is linear.
As fluid flow raises a float in a tapered tube, increasing the area for passage of the fluid. The greater the flow, the higher the flow is raised.
The height of the float is directly proportional the flow rate. With liquids, the float is raised by a combination of the buoyancy of the liquid and the velocity head of the fluid.
With gases, buoyancy is negligible, and the float responds to the velocity head alone.
The float moves up or down in the tube in proportion to the fluid and the annular area between the float and the tube wall.
The float reaches a stable position in the tube when the upward force exerted by the flowing fluid equals the downward gravitational force exerted by the weight of the float.
