The main measuring element glass rotameter LZB-10 for small mounted on a vertical glass tube and including a large cone up and down movement of the float. When the fluid from bottom to top by a conical glass, creating a pressure differential between the upper and lower float, float to rise in this differential effect. When this rising force, buoyancy and viscosity of the float suffered gravity equal lift and float, the float is in equilibrium position. Therefore, the fluid flows through the float glass rotor flow meter ascent, there is a proportional relationship between the flow area that is glass rotor flowmeter, the position of the float height can be used as a measure of the flow. Use LZB-20 glass rotor flow meter is mainly used in various sectors of chemical, petroleum, light industry, medicine, fertilizer, chemical, food, dyes, environmental protection and scientific research, and to measure single-phase non-pulsating (liquid or gas) flow traffic. Corrosion resistant glass rotor flow meter is mainly used for corrosive liquids, gas detection medium flow, such as strong acids (except hydrofluoric acid), alkalis, oxidizing agents, strong oxidizing acids, organic solvents and other corrosive gases or liquids with Flow Detection glass rotor flowmeter LZB-50 media selection 1. The object of measurement. That measure media type, size of the pressure, and chemical properties. The liquid medium, gaseous medium, for corrosive media should choose decay meter. 2. LZB-100 meter performance itself. After the above-mentioned conditions determined Generally speaking, if the price is not a big change, it may be preferred needle into the upper part of the meter; there is a large hole in circulation is a direct flow scale; simple structure; the smaller external dimensions, etc. . In the case of small flow range, the choice of ball float, because it measured stable, easy to dust, high precision, good interchangeability. 3. Selection based on price. Generally speaking, high precision high price. According to the choice of instrument accuracy level measurement purposes, such as measuring media by only controlling the amount of adjustment by the test run, the future stability of the throughput to Always, so accuracy is secondary. 4. Fluid flows through the cone bottom-up, the fluid kinetic energy produced in the float buoyancy lift S and fluid the float rises A, S and buoyancy lift when A equals float its own gravity G, the float is in balance, stability in a a height position, indicating the scale of the fluid flow on the value of the cone glass rotameter Wenzhou Yueqing glass rotor flowmeter glass rotor flowmeter Wenzhou quotes, glass rotor flowmeter manufacturers in Wenzhou, Wenzhou flowmeter LZB
