Smart Electromagnetic Flowmeter

Overview

DWP yakatevedzana pombi mhando yakangwara electromagnetic flowmeter ndeye electromagnetic induction flowmeter, yakagadzirwa zvinoenderana neJB/T9248-999 "Electromagnetic Flowmeter", yakakodzera kuyerera kuverenga kwe conductive fluid ine conductivity yakakura kupfuura 5us/cm;dhayamita yezita renji i5 kusvika 3000, inoteedzana yemagetsi emagetsi flowmeter zvigadzirwa zvinosanganisa hungwaru, hudiki uye huremu hwekubatanidza, hwakawanda-kushanda, yakanyanya kunyatso uye kuvimbika kwepamusoro.Iyo ine zvikamu zviviri: sensor uye smart converter.

DWP electromagnetic flowmeter ine dzakasiyana siyana dzekushandisa.Inogona kuburitsa yakajairika chiratidzo chemazuva ano (4-20mA) inoenderana neHART yekutaurirana protocol paunenge uchisangana nekutarisa uye kuratidza pane-saiti, kurekodha, kugadzirisa, uye kutonga;inogona kushandiswa zvakanyanya muindasitiri yemakemikari, kuchengetedza kwezvakatipoteredza, uye indasitiri yemachira., simbi, migodhi, mushonga, kugadzira mapepa, mvura, chikafu, shuga, kubika uye mamwe maindasitiri ekuyerera kwemvura kuyerwa kweiyo conductive media mumapaipi ekugadzirisa;pamusoro pekuyera general conductive fluid, zvinoenderana nezvakakosha zvinodiwa nevashandisi, inogona zvakare kuyera conductive fluid-yakasimba maviri-chikamu Kuyerera, kuyerera kwepamusoro viscosity zvinwiwa uye zvinwiwa zvakaita semunyu, asidhi yakasimba, uye alkali yakasimba.

Zvimiro

(1) Sensor:

Iyo sensor inonyanya kuumbwa necatheter yekuyeresa, yekuyeresa electrode, coil yekukurudzira, iron core, magineti uye imba.

Measuring conduit: Iyo inoumbwa nesimbi isina simbi conduit, lining uye yekubatanidza flange, uye ndiyo inotakura yekuyera pane-saiti yemvura inoyerwa.

Kuyeresa maelectrodes: peya yema electrode akaiswa pamadziro emukati measuring conduit, perpendicular to the axial flow direction, kuitira kuti mvura yekuyera ibudise zviratidzo.

Excitation coil: Iyo yekumusoro uye yakaderera coil yekukurudzira inoburitsa magineti muyero catheter.

Iron musimboti uye magineti: Iyo magineti inogadzirwa neiyo yekukurudzira coil inounzwa mumvura uye inoumba magineti wedunhu.

Shell: kurongedza kwekunze kwechiridzwa.

(2) Shanduri:

Iyo ine hungwaru yechipiri mita, iyo inokwidziridza iyo yekuyerera chiratidzo uye ichiverengera nekamwe-chip komputa kuratidza kuyerera uye kuwanda kwehuwandu, uye inogona kuburitsa pulse, analog ikozvino uye mamwe masaini ekuyera kana kutonga kwekuyerera kwemvura.

(3) Fomu yekugadzira chigadzirwa:

Yakakamurwa kuita maviri mafomu: Integrated type uye split type.

Yakabatanidzwa mhando: Iyo sensor uye inoshandura inoiswa muchidimbu chimwe.

Split type: Iyo sensor uye inoshandura inoiswa zvakasiyana, uye inoyerera metering system inoumbwa nekubatanidza tambo.Kuti usangane nezvinodiwa zvekuyera kwakasiyana midhiya, iyo lining uye electrode zvinhu zve sensor zvinogona kuve nesarudzo dzakawanda.

Kushanda musimboti

Iyo yekushanda musimboti we electromagnetic flowmeter yakavakirwa pamutemo waFaraday we electromagnetic induction.Ndiko kuti, kana iyo conductive fluid ichiyerera kuburikidza ne electromagnetic flowmeter, induced electromotive simba inogadzirwa mune conductor.The induced electromotive force inoenderana nekuyerera kweiyo conductive fluid, iyo magineti induction intensity, uye hupamhi hwe conductor (yemukati dhayamita ye flowmeter), sezvakaratidzwa mumufananidzo.

Iyo induced electromotive force inoonekwa nepeya yemagetsi pamadziro eiyo flowmeter, uye kuyerera kweyero kunogona kuwanikwa kuburikidza nekuverenga.

Iyo induced electromotive force equation ndeye: E=KBVD

Mune fomula: E inokonzeresa kugona;D kuyera chubhu yemukati dhayamita;

B magnetic induction intensity;V avhareji yekuyerera velocity;

K is a coefficient ine chekuita nemagnetic field distribution uye axial urefu.
