The advantages and disadvantages of flow meter scale analysis

Abstract: the flow meter scale analysis the advantages and disadvantages of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Flow meter are cheap, convenient installation, especially in the measurement of small diameter and low-speed medium has a wide application. And shunda flowmeter factory technical below small make up, summarizes about flow meter is introduced, the advantages and disadvantages of hope can give you. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a flow meter scale analysis the advantages and disadvantages of the details. Flow meter are cheap, convenient installation, especially in the measurement of small diameter and low-speed medium has a wide application. Flow meter manufacturer technology below small make up, summarizes about flow meter is introduced, the advantages and disadvantages of hope can give you offer to help. Advantage: the flow meter used in small diameter and low flow velocity. Commonly used meter diameter 40 - Below 50 mm, zui do 1 small diameter. 5 - 4mm。 Suitable for measuring the low velocity of small flow rate, liquid, for example, diameter 10 mm float glass tube flowmeter under full flow of nominal pipe diameter, flow velocity in 0 only. 2 - 0. Between 6 m/s, even lower than 0. 1m/s； Metal tube flow meter and diameter greater than 15 mm float glass tube flowmeter is a bit higher, velocity at 0. 5 - 1. Between 5 m/s. Flow meter can be used for low Reynolds number, choose not float in the shape of viscosity, flow clearance Reynolds number as long as more than 40 or 500, Reynolds number flow coefficient that maintain a constant change, i. e. fluid viscosity change does not affect the flow coefficient. This value is far lower than the standard orifice throttling differential pressure meter zui low Reynolds number - 104 The requirements of 105. Most of the flow meter not straight pipe upstream requirements, or on the straight pipe upstream demand is not high. Flow meter has a wide flow range of degrees, generally 10:1, zui to a 5-1, zui high as 25:1. The output of the flow detecting element close to linear. The pressure loss is low. Glass tube flow meter has simple structure, low cost. As long as the instructions given flow is easy to use, the disadvantage is that there is the risk of glass tube is fragile, especially the structure of undirected float for gas. Metal tube flow meter with no taper pipe rupture risk. Compared with the glass tube flow meter, using a wide range of temperature and pressure. Most of the structure of flow meter can only be used for pipeline installation of vertical flow from bottom to top. Weakness: the flow meter application is limited to small diameter, normal flow type flow meter cannot be applied to big diameter, zui large diameter 100 mm float glass tube flowmeter, metal tube flow meter is 150 mm, larger diameter can only use FenLiuXing instrument. Using fluid and not at the same time, the factory calibration fluid to flow value for amendment. Liquid with float flowmeter calibration, usually with water gas with air calibration, such as the actual use of fluid density, viscosity, and different, traffic to deviate from the original index values, is to be a conversion, use is relatively complex. Above is the summary of the advantages and disadvantages about the flow meter is introduced, and if you have other questions or requirements about flow meter, can flow meter manufacturer, we will serve you wholeheartedly. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
