Balance meter was introduced in detail

Abstract: the detailed information of balance meter was produced by excellent flow meter, flow meter manufacturer to offer you the quotation. HNPH series balance meter have greatly improved the traditional throttling device, has a balance of rectifier characteristics significantly. Traditional throttling device is only one aperture, throttling after fluid lost ideal state; And balance meter aperture has multiple functions, can. More flow meter manufacturers choose model price quote you are welcome to inquire, here is balance meter scale detailed introduction for details. HNPH series balance meter have greatly improved the traditional throttling device, has a balance of rectifier characteristics significantly. Traditional throttling device is only one aperture, throttling after fluid lost ideal state; And balance meter aperture has multiple functions, to limit the flow field zui balance rectifier as ideal fluid, thus the advantage of the differential pressure flowmeter play incisively and vividly. Balance measurement meter is suitable for almost all fluid is a fluid measurement technology revolution, the current balance flowmeter has been widely used in petroleum, chemical industry, metallurgy, electricity, gas, water treatment and other industries. Is a revolutionary product balance principle flowmeter differential pressure type flow meter, its working principle is the same as other differential pressure flowmeter, are based on the principle of energy conversion in the sealing pipe: in the case of ideal fluid in the pipeline flow is proportional to the square root of the differential pressure. Used to measure the differential value according to the Bernoulli equation to calculate the flow in the pipeline. Balance disc throttling of flow sensor is a porous rectifier, installed on the cross section of the pipeline, the size and distribution of each hole is based on the special formula and test data, and custom, called the function. When fluid through the function of the disc holes, the fluid will be balanced rectification, eddy current is small zui, form the approximate ideal fluid, through pressure device, can obtain the stability of the differential pressure signal, according to the Bernoulli equation, to calculate the volume flow to mass flow. Balance the characteristics of the meter 1, the accuracy of measurement is 2, 5 ~ 10 times that of the standard orifice flow noise is 1/153, * the pressure loss of the standard orifice plate is 1/34 of the standard orifice plate, pressure recovery is faster than the standard orifice plate 2 times 5, zui small straight pipe can be less than zero. 5 d a, high linearity and repeatability equilibrium flow sensor are symmetric porous structure, able to balance the flow field, reduce the eddy current, vibration and noise signal, the flow field greatly improve the stability and the linearity than orifice up 5 ~ 10 times, repetitive increased by 54%, 0. 15%, from the point of its comprehensive performance, balance meter belongs to high-grade flowmeter. 5-1 range than the linearity of & plusmn; 0. 3%; 7:1 range than the linearity of & plusmn; 0. 5%; Now range than the linearity of & plusmn; 1. 0% 2, straight pipe required low balance flow sensor due to the stable flow field, and restore two times faster than orifice pressure, greatly short by the requirement for straight pipe before and after the straight pipe is commonly before 3 d after 1 d, zui small can be less than zero. 5 d, so as to save a lot of straight pipe, especially special expensive materials of pipes. Three pressure loss, reduce * porous symmetrical balance design, reduces the turbulent shear stress and the formation of eddy current, reduce the loss of kinetic energy in the same measurement conditions, compared with the orifice plate 2. Five times the pressure loss, saving considerable run energy cost, is a kind of energy-saving instrument, worth of promotion. Four, dirt resistant plugging porous symmetrical balance design, reduces the turbulent shear stress and the formation of eddy current, thus greatly reduces the stranded dead zones, ensure pore smudgy smooth through multiple media and reduce the chance of a fluid hole blocked. Five, can directly replace orifice plate with the orifice plate with the same method of use and appearance, so you can directly to replace, do not need any piping changes and changes of related instrument, very suitable for the energy measurement transformation in orifice flowmeter to balance. Six, wide range of flow measurement based on test results, we know that: balance the performance of the flowmeter, the flow velocity can be from small zui to sound; The small zui Reynolds number can be lower than 200, zui large Reynolds number is larger than 107; β The value of optional 0. 25 ~ 0. 90. Seven, long-term stability is good because of its obvious turbulent shear stress decreases, and greatly reduce the friction between the throttling parts directly, its & beta; Values remain unchanged for a long time, the whole instrument have no moving parts, so can maintain stability for a long time. Eight, measurable medium of high temperature and high pressure and orifice throttling device, working temperature and pressure depends on the material and pipe and the flange level, working temperature is 850 ℃, pressure can be up to 42 mpa. Nine, measurable complex working condition of medium because of its special structural design, make its have special performance, it can undertake gas-liquid two phase, all kinds of mixed gas ( Such as gas, methane gas, coal gas, etc. ) , all kinds of low temperature gas ( Such as LNG, liquid nitrogen, liquid oxygen, liquid argon, liquid hydrogen, liquid chlorine, liquefied ethylene, liquefied petroleum gas, etc. ) , gas liquid two phase medium ( Such as moisture) , pulp, multiphase flow, vibration, electromagnetic interference and two-way flow of medium flow ( Because the balance meter or so completely symmetrical) 。 Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
