Smart Electromagnetic Flowmeter

Dubawa

DWP jerin bututun nau'in na'ura mai ba da hanya tsakanin hanyoyin sadarwa shine ma'aunin induction na lantarki, wanda aka tsara bisa ga JB/T9248-999 "Electromagnetic Flowmeter", wanda ya dace da lissafin kwararar ruwa mai gudana tare da haɓakawa fiye da 5us/cm;Naminal diamita kewayon ne 5 To 3000, shi ne jerin electromagnetic flowmeter kayayyakin hadewa hankali, ƙanana da nauyi hadewa, Multi-aiki, high daidaito da kuma high AMINCI.Ya ƙunshi sassa biyu: Sensor da smart Converter.

DWP electromagnetic flowmeter yana da fa'idar amfani.Zai iya fitar da siginar daidaitattun sigina na yanzu (4-20mA) daidai da ka'idar sadarwa ta HART yayin saduwa da saka idanu da nunin wurin, don rikodi, daidaitawa, da sarrafawa;ana iya amfani da shi sosai a masana'antar sinadarai, kariyar muhalli, da masana'antar yadi., Karfe, ma'adinai, magani, takarda, samar da ruwa, abinci, sugar, Brewing da sauran masana'antu domin ruwa kwarara auna na conductive kafofin watsa labarai a aiwatar bututu;baya ga auna janar conductive ruwa, bisa ga musamman bukatun na masu amfani, kuma zai iya auna conductive ruwa-m m Gudun lokaci biyu, kwarara na high danko ruwa da kuma ruwaye kamar gishiri, da karfi acid, da kuma karfi alkalis.

Tsarin

(1) Sensor:

Na'urar firikwensin ya ƙunshi babban catheter mai aunawa, lantarki mai aunawa, na'urar motsa jiki, ainihin ƙarfe, magnet da kuma gidaje.

Auna magudanar ruwa: Ya ƙunshi magudanar bakin karfe, rufi da haɗin flange, kuma shine mai ɗaukar ruwa a kan wurin da za a auna.

Aunawa na'urorin lantarki: nau'ikan lantarki guda biyu da aka sanya akan bangon ciki na ma'aunin ma'aunin ruwa, daidai gwargwado ga hanyar kwararar axial, ta yadda ruwan ma'aunin ya haifar da sigina.

Excitation Coil: Ƙwayoyin motsa jiki na sama da na ƙasa waɗanda ke haifar da filin maganadisu a cikin catheter na aunawa.

Ƙarfin ƙarfe da maganadisu: Filin maganadisu da ke haifar da naɗaɗɗen tashin hankali ana shigar da shi cikin ruwa kuma ya samar da da'irar maganadisu.

Shell: marufi na waje na kayan aiki.

(2) Mai canzawa:

Mita ce ta sakandare mai hankali, wacce ke haɓaka siginar kwarara kuma tana ƙididdige ta da kwamfuta mai guntu guda ɗaya don nuna magudanar ruwa da adadin adadin, kuma tana iya fitar da bugun bugun jini, halin yanzu da sauran sigina don aunawa ko sarrafa kwararar ruwa.

(3) Samfurin haduwar samfur:

An raba shi zuwa nau'i biyu: nau'in haɗaka da nau'in tsaga.

Nau'in Haɗe-haɗe: Ana shigar da firikwensin da mai canzawa a yanki ɗaya.

Nau'in tsaga: Ana shigar da firikwensin da mai canzawa daban, kuma ana yin tsarin auna ma'aunin ta hanyar haɗa igiyoyi.Domin biyan buƙatun ma'aunin watsa labarai daban-daban, kayan rufi da kayan lantarki na firikwensin na iya samun zaɓi da yawa.

Ƙa'idar aiki

Ƙa'idar aiki na lantarki mai motsi ta dogara ne akan dokar Faraday ta shigar da wutar lantarki.Wato lokacin da ruwan da ke gudana ya gudana ta hanyar na'urar motsi na lantarki, za a haifar da ƙarfin lantarki da aka haifar a cikin madubin.Ƙarfin wutar lantarki da aka jawo ya yi daidai da yawan kwararar ruwa mai tafiyarwa, ƙarfin induction na maganadisu, da faɗin jagorar (diamita na ciki na ma'aunin motsi), kamar yadda aka nuna a cikin adadi.

Ana gano ƙarfin lantarki da aka jawo ta hanyar nau'ikan lantarki guda biyu akan bangon na'urar motsa jiki, kuma ana iya samun adadin kwarara ta hanyar lissafi.

Ma'aunin ƙarfin lantarki da aka jawo shine: E=KBVD

A cikin dabara: E ya haifar da yuwuwar;D bututu mai auna diamita;

B ƙarfin shigar da magnetic;V matsakaicin saurin gudu;

K shine ƙididdiga mai alaƙa da rarraba filin maganadisu da tsayin axial.
