Glass Tube Flowmeter
LZB Series Variable-area FLow meter mainly applies to areas like chemistry, oil industry, light industry, medicine, chemical fertilizer industry, food industry, dye industry, environment 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, oxidezer, strong oxidizing acid and organic solvent.
Characteristics
- Small pressure loss
- Reliable performance, easy and convenient to read
- Simple structure, convenient to install and serviced
- Low and reasonable price
Principles and Structures
The most important measuring component of flowmeter is a vertical – installed tapered glass pope witha floater that is free to move up and down. When fluid movers through the flowmeter from bottom to top, pressure difference wil 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 throguh 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.
