Variable Area Rotameter

LZB/LZJ series glass tube flow meter

LZB/LZJ series glass tube flow meter
Summary
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.
