Environmental equipment and instruments used glass rotameter LZB model rotameter corrosion Description: glass rotameter mainly used in various sectors of chemical, petroleum, light industry, medicine, fertilizer, chemical, food, dyes, environmental protection and scientific research, the use to measure single-phase non-pulsating (liquid or gas) flow rate of the fluid. Corrosion resistant glass rotameter corrosive liquids mainly used to detect the flow of gaseous media, such as strong acids (except hydrofluoric acid), alkalis, oxidizing agents, strong oxidizing acids, organic solvents and other corrosive gases or liquids have medium flow testing. Optional: 1. Object measured. That measure media type, size of the pressure, and chemical properties. Such as a liquid medium, the gas medium, for corrosive media should choose decay meter. 2. Flowmeter performance itself. After the above-mentioned conditions are determined Generally speaking, if the price is not a big change, may be preferred needle placed in the upper part of the meter; there is a large hole in circulation is a direct flow of scale; simple structure; the smaller external dimensions, etc. . If so you can choose a small flow range balls float, because it measure stability, not 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 the only control measure by the amount of media, through commissioning adjustments need has stabilized after the throughput, so accuracy is secondary. 4. Fluid flows through the cone bottom-up, fluid kinetic energy generated on the float buoyancy lift S and A fluid the float rises, when the lift and buoyancy S A sum equal to float its own gravity G, the float is in equilibrium and stability in a a height position indicator on the cone scale flow value of the fluid.
