One. Product overview

Balance meter to greatly improve the traditional throttling device, has a balance of rectifier characteristics significantly.Traditional throttling device is only one aperture, throttling after make fluid lost ideal fluid, thus the advantage of the differential pressure flowmeter play incisively and vividly.Balanced flow is suitable for almost all fluid measurement, 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.

2. The working principle of the product

Equilibrium flow meter is a revolutionary 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 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 the flow sensor is a porous disc throttling device, installed on the cross section of the pipeline, the size and distribution of each hole were made based on the special formula and test data, called the function.When 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.

3. Product features

1, high linearity and repeatability.Balance the flow sensor with symmetric porous structure characteristics, able to balance flow field,

Reduce the eddy current, vibration and noise signal, high stability, flow field linearity than orifice increased 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%

2, low straight pipe.Stability of equilibrium flow sensor due to the flow field, and restore two times faster than orifice pressure, greatly reducing 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.

3, reduce the permanent pressure.Porous symmetrical balance design, reduces the turbulent shear blade 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.

4, dirt resistance is not easy to block.Porous symmetrical balance design, reduces the turbulent shear blade 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 plug.

5, can be directly replace orifice.With the orifice plate with the same method of use and appearance, so you can directly replace don't need any changes and changes of related instrument, very suitable for the energy measurement EMS transformation in orifice flowmeter to balance.

6. Wide range of flow measurement.According to the test results, balance the performance of the flowmeter, the flow velocity can be from the least to the speed of sound, its smallest Reynolds number can be less than 200, the largest Reynolds number greater than 107:;Beta optional 0.5 ~ 0.90.

7, good long-term stability.Because of the turbulent shear knife decreased significantly, 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.

8, 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 ℃, pressure can be up to 42 mpa.

9, measurable complex working condition of impurities.Because of its special structural design, make its have special performance, it can undertake gas-liquid two phase, all sorts of mixed gases (such as gas, methane gas, coal gas, etc.), all kinds of cryogenic gases (such as LNG, liquid nitrogen, liquid oxygen and 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).
