Working principle and the use of glass rotameter scale

Abstract: the working principle and application of glass rotameter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Glass rotor flowmeter is a kind of variable area flowmeter, it is mainly composed of a bottom-up expand the taper pipe and a vertical glass can move up and down with the flow of float. Because through the flowmeter flow and float higher level ( That is, traffic. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a glass rotameter scale working principle and the use of the article details. Glass rotor flowmeter is a kind of variable area flowmeter, it is mainly composed of a bottom-up expand the taper pipe and a vertical glass can move up and down with the flow of float. Because through the flowmeter flow and float higher level ( I. e. the flowmeter flow area) Has certain function relation between the height of the float position can be used as flow measurement value. Suitable for measuring single-phase pulsating fluid ( Liquid or gas) The traffic. Glass rotor flowmeter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and measurement test, scientific research departments, measurement of single-phase pulsating fluid ( Liquid or gas) The traffic. Glass rotameter is commonly used in industry and laboratory zui a flowmeter. It has the structure is simple, intuitive, small pressure loss, easy maintenance, etc. Glass rotor flowmeter is suitable for the measurement by small flow rate, pipe diameter 150 mm can also measure the rate of flow of corrosive medium. When using flow meter must be installed in vertical direction of the section, the fluid to pass from bottom to top. Glass rotameter main measuring element for a vertical installed under the small big tapered glass tube, and can move up and down float. When the fluid by the tapered glass tube from bottom to top, produce pressure differential between the float up and down, float in the role of the differential pressure rise. When the rising and float of buoyancy and viscous equals the lift force and the gravity of the float, float in the equilibrium position. Therefore, through the glass rotor flowmeter in the fluid flow and float higher level, namely with glass rotameter circulation area, there exists a certain proportion relationship between the position of the float height can be used as flow measurement. Working principle of the glass rotameter glass rotameter by upward expansion tapered circular tube and tube of the float. Float in the vertical position of h and conical tube flow Q into one-to-one correspondence relationship. Glass rotameter is composed of two parts, a glass rotor flowmeter is from bottom to expand gradually tapered tube; Another glass rotor flowmeter is put in tapered tube and can move freely up and down along the pipe axis rotor. When measuring the flow of fluid, be from current tapered tube bottom flow and fluid flow through the rotor, and generate a force to it ( The size of the force changes with the flow) ； When the flow is large enough, produced by the force to the rotor lift, and rising. At the same time, by current flowing through the body between the rotor and conical wall circular cross section, from the top. When is current body fluid force on rotor, at the right moment is equal to the weight of the rotor in the fluid ( Called show weight) , the rotor stress equilibrium and stay at a certain level. Analysis shows that; The position of the rotor in the tapered tube height, and through the flow with the corresponding relationship each other. Therefore, observing the rotor position in the tapered tube height, the corresponding flow values are obtained. Glass rotor flowmeter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and measurement test, scientific research departments, measurement of single-phase pulsating fluid ( Liquid or gas) The traffic. Glass rotor flowmeter has the strong corrosion performance, can detect acid ( Except hydrofluoric acid) , alkali, oxidant and other corrosive gas or liquid flow, glass rotor flowmeter is suitable for chemical, pharmaceutical, paper making, sewage treatment and other industries. Glass rotor flowmeter operation 1, flow meter, when using should be slowly open upstream of the valve to open, then use flowmeter downstream of the regulator to adjust the flow rate. Meter stop using, should be slowly closing valve upstream of the flow meter, and then close the flowmeter downstream of the flow control valve. 2, flowmeter must stay behind the float stability can read values. The float reading position: float zui to read where large diameter. 3, when using, should avoid being measurement of body temperature and pressure of rapid change. To prevent the taper pipe break cuts. 4, such as taper pipe, float contamination should be cleaned in time. 5, float working diameter is measured and sharp edges, if there is any damage should be calibration again. 6, flow meter need remove, should be familiar with its structure, especially when disassembling gland, the plate bolts should be firstly, prevent broken cone tube. 7, passes through the flow state of fluid density, temperature, pressure and dividing different state ( The standard state) You must to modify values. 8, use the meter should be checked on a regular basis, such as to found leakage should be will flow meter and pressure relief, and then evenly tighten gland, should avoid gland tight minced taper pipe. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
