Product Description of Glass Rotameter
LZB/LZJ series glass rotameter are widely used in 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 (liquid or gas). LZB/( )F/LZJ-( )F series 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.
Working Principle & Structure of Glass Rotameter
The flowmeter is mainly composed of a piece of taper glass pipe with bigger bottom and smaller top and a floater moving up and down along with the fluid flow(Fig.3).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.
The taper pipe of LZB/LZB-( )F flowmeter is a pipe with smooth inner wall of Glass Rotameter
For the flowmeter with the bore larger than DNl5, the floater moves up and down along the guide rod and remains stable ;There are three guiding edges on the inner wall of the taper pipe of LZJ/LZJ-()F flowmeter to keep the floater stable (See Fig.5).The flowmeter with the bore smaller than DNl0 adopts hose connection, is equipped with needle flow control valve;The flowmeter with the bore larger than DN15 adopts flanged connection.
