Abstract: LUGB technical characteristics of vortex flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. With the rapid development of modern measuring technology, all kinds of flowmeter emerge in endlessly, constantly improve the measuring precision, use scope, installation and maintenance is simple. This article introduced the LUGB vortex street flowmeter with its wide measuring range, high measurement precision, wide range of applications. More flow meter manufacturers choose model price quote you are welcome to inquire, here is LUGB technical characteristics of vortex flow meter scale article details. With the rapid development of modern measuring technology, all kinds of flowmeter emerge in endlessly, constantly improve the measuring precision, use scope, installation and maintenance is simple. This article introduced the LUGB vortex flowmeter with its wide measuring range, high measurement precision, is widely used in industrial production of medium such as water, steam, compressed air measurement. In this paper, the structure of the instrument, working principle and field application are discussed in aspects of technical characteristics and application of this instrument. 1 structure composition and working principle as shown in figure 1: vortex flowmeter by vortex occurred ( Triangular prism) And detecting head, table body, connecting the prop, the amplifier, etc. Figure 1 type of vortex street flowmeter LUGB vortex flow sensor is the basis of the principle of karman vortex street and modern electronic technology design and manufacture of a flow sensor. Applicable to the industry of liquid, gas, steam flow measurement, and measurable turbid liquid containing impurities, tiny particles. When the current flowing through the body vortex occurs when the body, in the event of a body on both sides of the back of the alternated two columns, form & other; Vortex street & throughout; As shown in figure 2. The vortex frequency is proportional to the velocity of the fluid, under certain conditions in accordance with type: type: f: vortex frequency St: strouhal number V: velocity d: the width of the vortex occurred body figure 2 vortex schematic vortex in the whirlpool of fluctuating pressure, which occurred at the back of the body changes by piezoelectric sensor signal transform it into electrical signals, after dealing with the transmitter transformation become pulse or standard signal output. 2 technical characteristics ( 1) The flow measurement range, high measuring accuracy, small pressure loss. Nominal diameter DN10 ~ DN500. ( 2) Simple structure, no moving parts, reliable operation, good durability and long service life. ( 3) Measuring accuracy is not affected by fluid pressure, viscosity and density. Wide application and industrial measurement, the accuracy level 0. Level 5. ( 4) Resistance to environmental anti-vibration effect is strong. The measurable temperature zui up to + 380 ℃. ( 5) + - signal output current 4 ~ 20 ma, the pulse signal, HART protocol, etc. , used widely. ( 6) Suitable for gas, liquid, steam and other media. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
