Product overview
LWS series sanitary turbine flowmeter is a kind of flow meter widely used in pharmaceutical, food, beverage and other industries as metering, batching, control, finished product filling and other purposes. The shell of the instrument is made of stainless steel (316L), and the movement part is made of special material, which has good anti-corrosion and anti rust ability. The whole surface structure breaks through the traditional technology and adopts good anti-corrosion ability. The accuracy and repeatability of the instrument are greatly improved. It is specially designed for pharmaceutical and beverage industries. It adopts quick installation connection structure, which is convenient for cleaning. LWS series sanitary turbine flowmeter has reached the international standard of similar products and is an ideal instrument for sanitary industry.
