Tianjian U-ideal Balance Flow Meter;Multi-core Orifice flow meter for Superheated Steam
UL-series balance flowmeters have greatly improved the traditional throttling device with 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, balance the flowmeter can maximize the rectifier into ideal fluid flow field in balance, thus the advantage of the differential pressure flowmeter play incisively and vividly. Balance measurement meter is suitable for almost all fluid, it 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.
Balance principle flowmeter products
Balance orifice flow meter is a revolutionary differential pressure type flow meter, its working principle and balance flowmeter other differential pressure flowmeter, are based on the principle of energy conversion in the sealing pipe: in the case of ideal fluid in pipe 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. Balance meter when the fluid through the function of the disc holes, the fluid will be balanced rectification, eddy current is minimized, 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.
The characteristics of the equilibrium flow meter
1, balance meter measuring precision is 5 ~ 10 times of the standard orifice plate
2, balance meter flow noise is 1/15 of the standard orifice plate
3, balance is the 1/3 of standard orifice flowmeter permanent pressure loss
4, balance meter pressure recovery 2 times faster than the standard orifice plate
5, minimum balance meter straight pipe can be less than 0.5 D
A, balance meter high linearity, repeatability is good
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%, to 0.15%, from the point of its comprehensive performance, balance meter belongs to high-grade flowmeter.
5-1 range than the linearity of plus or minus 0.3%;
7:1 range than the linearity of plus or minus 0.5%;
Now range than the linearity of plus or minus 1.0%
Second, balance meter low demands on straight pipe
Stability of equilibrium flow sensor due to the 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, the minimum can be less than 0.5 D, so as to save a lot of straight pipe, especially special expensive materials of pipes.
Three, balance meter reduce permanent pressure loss
Porous balance meter 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, reduced 2.5 times compared with the orifice of the permanent pressure loss, saving considerable energy cost, operation is a kind of energy-saving instrument, worth of promotion.
Four, dirt resistance is not easy to block
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
With the balance of orifice flow meter, 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
According to experimental results, we know that: balance the performance of the flowmeter, the flow velocity can be from the least to the speed of sound; The smallest Reynolds number can be less than 200, the biggest Reynolds number greater than 107; Beta optional 0.25 ~ 0.90.
Seven, long-term stability is good
Because of its obvious turbulent shear stress decreases, and greatly reduces the friction between the throttling parts directly, its beta remain unchanged for a long time, the whole instrument have no moving parts, so can maintain stability for a long time.
Eight, balance meter high temperature and high pressure medium can be obtained
With orifice throttling device, such as work depends on the temperature and pressure piping and flange material and grade, working temperature is 850 ºC, 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, a variety of mixed gases (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 balance meter or so completely symmetric).
