Defination : Glass Tube Rotameter 


The Glass Tube Rotameter with Flanges are relatively simple and reliable instruments for measuring continuous flow rate indication.


Manufacturing Process:


This Glass Tube Rotameter consists of a vertical mounted, calibrated with tapered Glass tube, with float inside and a scale directly calibrated as per flow range. Glass Tube field are replicable without disturbing the end connection.


End Connection : Generally, End connection, some times called as a Top-Bottom Connection or Inlet-Outlet connection, fitted with suitable line size flanges, in a grade of Stainless Steel 304 /316 or MS or PP material.


How it works:


Your line fluid raises the float in tapered Glass Tube area, increases as float moves upward, thereby showing the exact (Increasing) flow in the glass tube.




Glass Tube Rota meter are generally used for, measuring the flow Range of  Air, Water, Chemical and Gases.
