Summary
LZB - () S plastic tube float flowmeter is designed for some special occasions and has a certain anti-corrosion performance for measuring liquid. It is mainly used in chemical industry, light industry, medical treatment, and environmental protection, especially suitable for occasions that cannot contact with metal and widely used in environmental protection drainage treatment.
