DESCRIPTION :

Glass tube Rotameter Flowmeter are widely used in water treatment .chemical industry, petroleum, light industry, medicine, environmental 

protection, food, measurement, testing and scientific research institutes. They are used to measure the flow rate of single-phase non-pulse

fluid ,say water ,air , liquid and gas .  

Anti-corrosive glass rotameter have a good corrosion resistance, and can be used to measure acid (except hydrofluoric acid), alkali, 

oxidizer and other corrosive gases or liquid. They are suitable for chemical industry, pharmacy, papermaking, sewage disposal etc.    

The flowmeter is mainly composed of a piece of taper glass pipe with bigger top and smaller bottom，a floater moving up and down along

with the fluid flow.When the fluid flows across the taper pipe from bottom to top, the floater rises under the lift force "S" on the floater due

to the fluid dynamic energy and the fluid buoyancy force "A".When the sum of the lift force "S" and the buoyancy force "A" is equal to the floater

weight "G", the floater is in equilibrium and stable at a certain height. The scale on the taper pipe indicates the fluid flow.                         

EXAMPLE: 

Glass Tube Rotameter Flowmeter G/R/F series.This series have both normal type (using for general noncorrosive fluid) 

and anticorrosiontype(using  for corrosive fluid.).This series are designed with compactness,light structure, nice figure,

convenient maintenance,safe and reliability, easy installation.The flange of F10, 20, 30 types can rotate to be aligned easily.

G/R/F10, 20, 30 glass tube flowmeter has the following connections: Threaded type(G10, 20, 30 types),

hose type(R10, 20,30 types),flange type(F10,20,30 types)
