ZW-CDH series Multi throat air flow measurement device ，按照速度面積法布置的一種新型流量傳感器

。">Is the development from the foundation Kiel tube, according to a new flow sensor layout area velocity method. 。">It is a perfect combination of throttle type flow sensor and measuring method of the velocity area method. ，從而得到流量

。">The sensor is composed of a plurality of Kiel probe according to the velocity area method is inserted into the pipe, will take the pressure signal into the pipe, resulting in flow. 、冶金

、熱電行業(yè)有含塵煙氣的超大管徑的流量測量中。">The measuring accuracy is high, mainly used in petrochemical, metallurgy, thermal power industry dust of the large diameter flow measurement. ，運(yùn)輸

、安裝更為便捷。">The cost is relatively low, more convenient transportation and installation.

、工作原理：">Two, work principle:

，當(dāng)流體經(jīng)過喉徑管時(shí)

，通過收縮段喉部流向擴(kuò)散角。">ZW-CDH series multi throat diameter air flow measurement device based on the principle of fluid mechanics, when the fluid passes through the throat pipe, through the throat contraction flow diffusion angle.

，喉部的流體被整流和放大

，極大的提高了喉部流速，使喉部的靜壓明顯下降

。">Through the diffusion suction diffusion angle on both sides of the throat, the fluid is rectification and amplification, which greatly improves the throat velocity, so that the throat pressure decreased significantly. 。">The static pressure so that the total pressure hole and throat measured difference amplification. ，就可以測的管道流量。">The greater the differential pressure flow is produced, by measuring the differential pressure, pipe flow can be measured.

；">Pl - population absolute static pressure measuring tube;

。">K. - pipe flow function;

；">TL: absolute temperature measuring tube fluid population;

；">K1 - meter correction factor;

A p - measuring tube population and throat diameter between differential pressure;

。">F (P, t) - temperature and pressure compensation function.

、應(yīng)用場合：">Third, application:

，實(shí)現(xiàn)單點(diǎn)

、多點(diǎn)高精度測量的差壓式智能流量計(jì)。">ZW-CDH series multi throat diameter air flow measurement device is based on the Bernoulli equation, the use of modern aviation technology -- Theory of aerodynamics and fluid mechanics theory, to achieve a single point, multi-point high precision measurement of differential pressure flowmeter. 、鋼鐵廠

、化工廠的大、中

、小型管道常溫或高溫氣體（空氣

、蒸汽、天然氣

、煤氣

、煙氣）流量測量，特別適用于火電廠一次風(fēng)

、二次風(fēng)流量測量

。">It is widely used in thermal power plant, steel plant, chemical plant, small and medium sized pipeline at ambient temperature or high temperature gas (air, steam, gas, gas, gas) flow measurement, especially suitable for power plant primary air, secondary air flow measurement.

Fourth, the main features:

、根據(jù)現(xiàn)場工藝條件的不同分為單喉徑和多喉徑兩種

；">1, according to different process conditions for single and multi pore throat diameter of both;

，管徑大于φ300mm的管徑其壓力損失可以忽略不計(jì)

，節(jié)能效果顯著

；">2, small pressure loss, the diameter is larger than the diameter of the 300mm diameter pressure loss can be neglected, the energy saving effect is remarkable;

。">Low 3 and straight pipe.

，前直管段長度為0.7—1.5D；">In general, the tube length is 0.7 1.5D;

、差壓值大

。">4, differential pressure value.

；">The small flow rate condition, still get a larger differential pressure value;

、信號穩(wěn)定可靠，無脈動(dòng)差壓信號

。">5, stable and reliable signal, no pulse differential pressure signal.

，使得被測介質(zhì)在各節(jié)流段有一個(gè)被“整流”的過程，zui大限度的消除了渦流的影響

；">Due to the adoption of the "throat" structure, so that the measured medium in each throttle segment has a "rectification" process, Zui can eliminate the influence of the eddy current;

、特殊的布點(diǎn)結(jié)構(gòu)，可以得到整個(gè)管道截面的測量數(shù)據(jù)

，從而保證測量的真實(shí)性和準(zhǔn)確性

；">6, the special distribution structure, can get the measurement data of the whole cross section of the pipeline, so as to ensure the authenticity and accuracy of measurement;
