LZB / LZJ Glass rotor flowmeter has been widely used in chemical, petroleum, light industry, medicine, environmental protection, food and Metrology, scientific research and other departments, non-pulsating flow measurement of single-phase (liquid or gas) flow¡£
LZB / () F/LZJ- () F Series Rotameter corrosion-resistant glass has strong corrosion resistance, can detect acid (except hydrofluoric acid), alkalis, oxidizing agents and other corrosive gas or liquid flow, Used in chemical, pharmaceutical, paper making, sewage treatment and other industries¡£

Principle and structure
Mainly by an expansion of bottom-up flow tapered glass tube and a fluid flow with the size of the float moves up and down (Figure 3). Fluid flows through the cone bottom, the fluid kinetic energy generated in the lift on the float and fluid buoyancy S A to float up, when the lift A of S and buoyancy float its own gravity and is equal to G, the float is in equilibrium, stability in a A high degree of position, the scale on the cone of directions of fluid flow value¡£
Flow meter readings in the position of the float as shown in Figure 2:

LZB/LZB- () F for the smooth flow of the cone inner tube (see Figure 4), more than DN15 flow path, the float is moved through the guide rod to maintain stability; LZJ/LZJ- () F Cone Flow Meter Oriented convex inner wall has three bars, the float remained stable (see Figure 4). DN10 diameter hose connection using the following flow meter, with a needle flow control valve; meter diameter than DN15 flange connection¡£
