Glass rotor flowmeterWorking principle and application scope:
Working Principle:

Glass rotor flowmeterIt mainly consists of a conical glass tube that expands from bottom to top and a stainless steel float that moves up and down with the fluid flow rate (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 ZW-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 ZW-LZJ-() F flowmeter, which keep the float stable (see Figure 4). 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.

Application scope:
Glass rotor flowmeterIt is mainly used in various departments such as chemical, petroleum, light industry, medicine, fertilizer, synthetic fiber, food, dye, environmental protection, and scientific research to measure the flow rate of single-phase non pulsating (liquid or gas) fluids.
The anti-corrosion type is mainly used for detecting the flow rate of corrosive liquids and gas media, such as strong acids (except hydrofluoric acid), strong bases, oxidants, strong oxidizing acids, organic solvents, and other corrosive gas or liquid media.
