Product details
Anti corrosion glass rotor flowmeterProduct model: LZB、LZJ
Overview of anti-corrosion glass rotor flowmeter
The LZB/LZJ series glass rotor flowmeter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and metrology testing, scientific research and other departments to measure the flow rate of single-phase non pulsating fluids (liquids or gases).
The LZB/() F/LZJ - () F series corrosion-resistant glass rotor flowmeter has strong corrosion resistance and can detect the flow rate of acids (except hydrofluoric acid), alkalis, oxidants, and other corrosive gases or liquids. It is suitable for industries such as chemical, pharmaceutical, papermaking, and sewage treatment.

principle and structure
The flowmeter is mainly composed of a conical glass tube that expands from bottom to top and a float that moves up and down with the flow rate of the fluid (Figure 3). When the fluid flows through the conical tube from bottom to top, the lift S generated by the kinetic energy of the fluid on the float and the buoyancy A of the fluid cause the float to rise. When the sum of the lift S and buoyancy A is equal to the weight G of the float itself, the float is in equilibrium and stable at a certain height position. The scale on the conical tube indicates the flow rate value of the fluid.
The cone tube of LZB/LZB - () F flowmeter is a smooth inner wall tube (see Figure 4). For flowmeters with a diameter of DN15 or more, the float moves up and down through the guide rod to maintain stability; There are three guiding ribs on the inner wall of the cone tube of LZJ/LZJ - () F flowmeter, which keep the float stable (see Figure 5). Flow meters with a diameter of DN10 or less are connected by hoses and equipped with needle shaped flow control valves; Flow meters with a diameter of DN15 or above shall be connected with flanges.
