Overview

LZB Series Variable-area Flow meter mainly applies  to areas like chemistry, oil industry. light industry. medicine, chemical fertilizer industry, food industry. dye industry, environmental protection, and  scientific research. They are used to measure the  flow rate of unidirectional non-impulse fluid (liquid  or gas).
Corrosion resistance flow meter are mostly applied  in cases of corrosive liquid and gas, such as strong  acid (except for hydrofluoric acid) , strong alkali, oxidizer, strong oxidizing acid and organic solvent.

Characteristics

1) Small pressure loss 
2) Reliable performance, easy and convenient to read 
3) Simple structure, convenient to install and serviced 
4) Low and reasonable price

Principles and structures

The most important measuring component of flowmeter is a vertical-installed tapered  glass pipe with a floater that is free to move up and down. When fluid moves through  the flowmeter from bottom to top, pressure difference will be generated between the  fluid above the floater and the fluid below it, under which the float will ascend. When  this ascending force, the buoyancy force and viscosity force equal the gravity of the  float, the float will stop at this equilibrium position. Therefore, the flow rate through  the flow meter is relevant to the height of the float and the cutting area of the flow  meter. So the position of the float can be used to indicate the flow rate.
