Variable Area Flow meter (Rotameter)

Country of Origin: India
Technical Specifications:

•  Measures flow rate of fluids.
•  Consists of a vertically oriented glass (or plastic) tube with a larger end at the top.
•  Fluid flow causes the float to rise in the tube as the upward pressure differential and buoyancy of the fluid
  overcome the effect of the accuracy may be as good as 1-3% of full scale rating.
  
•  The tube can be calibrated and graduated in appropriate flow units
