Ibintu byo kwitaho mu gihe cyo gushyiraho ibipimo by'amashanyarazi muri sisitemu y'imiyoboro

Ibipimo by'amashanyarazi bipima umuvuduko w'amazi (EM) bikoreshwa cyane mu nganda, mu mirenge no mu bikorwa byo gutunganya amazi kubera ubuhanga bwabyo bwo hejuru, ubushobozi bwo gufata amazi atwara imizigo, no kugabanuka k'umuvuduko muke. Ariko, imikorere yabyo ishingiye cyane ku gushyiraho neza—ndetse n'ibipimo by'amashanyarazi bigezweho ntibitanga amakuru yizewe iyo bishyizwemo nabi. Kuva ku miterere y'imiyoboro kugeza ku bintu bifitanye isano n'ibidukikije, hari ibintu byinshi by'ingenzi bigomba kwitabwaho kugira ngo harebwe imikorere myiza. Iyi ngingo igaragaza ibintu by'ingenzi bigomba kwitabwaho mu gushyiraho ibipimo by'amashanyarazi mu miyoboro.

1. Ibisabwa ku burebure bw'umuyoboro ugororotse

Guhindagurika kw'imiyoboro ni kimwe mu bintu bibangamira cyane uburyo ibipimo bya EM bikoreshwa. Iyo amazi atemba mu nkokora, mu tumashini, mu tugabanya, cyangwa mu mapompo, bituma habaho imizunguruko, imizunguruko, cyangwa imivuduko idahuye, ibyo bikaba byabangamira ingufu za elegitoroniki ibipimo bikoresha mu gupima amazi. Kugira ngo ibi bigerweho, gukurikiza amabwiriza y'uburebure bw'imiyoboro igororotse yo hejuru n'iyo hepfo ni ngombwa.

Inganda nyinshi zitanga inama yo gukoresha nibura umurambararo w'umuyoboro (5D) uruta umuyoboro ugororotse (5D) ugereranije n'umuyoboro ugororotse uzamuka ugereranije n'umuyoboro wa EM n'umurambararo w'umuyoboro (3D) uruta umuyoboro ugororotse (3D). Urugero, niba ushyiramo metero mu muyoboro wa santimetero 100, hagomba kuba hari nibura metero 500 z'umuyoboro ugororotse mbere ya metero na santimetero 300 nyuma. Mu gihe umwanya ari muto (urugero: ibyumba bito by'imashini), gushyiraho ibikoresho bitanga amashanyarazi (nk'ibinyabiziga bitobora cyangwa ibyuma bifite imyobo) bishobora kugabanya uburebure bukenewe bugororotse binyuze mu gushimangira imiterere y'amazi. Irinde gushyiraho metero ako kanya nyuma ya pompe cyangwa valve zo kugenzura, kuko ibi bice bitanga umuyaga mwinshi.

2. Ingano y'umuyoboro n'uburyo uhuza ingano y'umuyoboro

Ingano z'imiyoboro n'ibipimo bidahuye neza bituma habaho imiterere idahwitse no kwiyongera k'umuvuduko w'amashanyarazi. Ibipimo bya EM byagenewe guhuza na diametre y'imiyoboro runaka (ingano y'umuvuduko), kandi guhitamo ingano idahwitse bigabanya imikorere yabyo.

Ntugace munsi y'ingano ya metero: Igipimo gito cyane gituma inzira y'amazi ifungana, bikongera umuvuduko w'amazi n'umuvuduko w'amazi ugabanuka. Ibi bishobora kwangiza umurongo w'icyuma uko igihe kigenda gihita bikanatera isura mbi y'amazi menshi.
Ntugakore ingano irenze urugero: Igipimo kinini cyane gitera umuvuduko muke w'amazi, cyane cyane iyo amazi atemba make. Kubera ko ibipimo bya EM byishingikiriza ku muvuduko uhoraho kugira ngo bikore ikimenyetso gipima amashanyarazi, umuvuduko muke ushobora gutuma imiterere idahindagurika cyangwa kunanirwa kumenya neza uko amazi atemba.

Niba ingano y'umuyoboro idahuye n'ingano zisanzwe za metero za EM (urugero: umuyoboro wa santimetero 5 udafite metero ihuye), koresha udukoresho two gupima cyangwa two kwagura imiyoboro twashyizweho nibura 10D hejuru ya metero kugira ngo uhindure hagati y'ingano. Menya neza ko udukoresho two gupima imiyoboro duto (atari utw'ibanga) kugira ngo wirinde ko habaho ikwirakwizwa ry'amazi ringana.

3. Uburyo bwo gushyiramo amazi n'uburyo bwo kuyashyiramo

Ibipimo bya EM bisaba ko umuyoboro wuzuzwa amazi yose mu gihe cyo gukora—imifuka y’umwuka cyangwa gazi ibangamira ingufu za electromagnetic kandi igatera ihindagurika ry’imiterere. Icyerekezo cyo gushyiraho bigira uruhare runini mu gukumira ubwiyongere bw’umwuka:

Gushyiraho mu buryo butambitse: Uburyo bwo gushyiramo ibintu bukunda gukoreshwa cyane. Shyira icyuma gipima amazi ku buryo electrode zacyo zishyirwa kuri 45° kugeza 90° uvuye hasi ku muyoboro (atari hasi neza). Ibi birinda ko electrode ihura n'ibisigazwa cyangwa imyanda igwa ku gice cyo hasi cy'umuyoboro, bishobora gutera umwanda. Binabuza imifuka y'umwuka guteranira hafi y'amashanyarazi (umwuka ukunda kuzamuka ukagera hejuru y'imiyoboro itambitse).
Gushyiraho uhagaze: Bikwiriye gukoreshwa hamwe n'amazi atemba hejuru (ntibijye bimanuka, kuko bishobora gufata umwuka kuri metero). Gushyiraho uhagaze bituma umuyoboro uhora wuzuye kandi bigafasha kwirinda kwirema kw'ibitaka. Ariko, menya neza ko metero igenwa mu gushyiraho uhagaze—imwe mu mashini zifite uburemere cyangwa icyerekezo cy'amazi atemba.
Irinde gushyiramo imiyoboro ku misozi miremire: Gushyiramo icyuma gipima umwuka ku gice cyo hejuru cy'umuyoboro byongera ibyago byo kugira aho umwuka uhagarara. Niba bidashoboka, ongeramo imyenge y'umwuka iri hejuru y'icyuma gipima umwuka kugira ngo urekure umwuka wafashwe.

4. Guhuza ibikoresho no kurengera ibidukikije

Ibice bya EM meter byatose (urusobe rw'imiyoboro, electrode) n'inyuma y'aho bipimye bigomba kuba bihuye n'amazi n'ibidukikije bikikije kugira ngo birambe kandi bigire umutekano.

Ibice bitose: Ku mazi yangiza (urugero: amazi yanduye aside, imiti ya shimi), koresha utwenda nka PTFE (Teflon) cyangwa FKM (Viton) hamwe na electrodes zikozwe muri Hastelloy C cyangwa titanium. Ku mazi yangiza (urugero: umwanda ufite ibintu bikomeye), hitamo utwenda twakomeye (polyurethane) kugira ngo wirinde kwangirika. Ku mazi meza, menya neza ko ibikoresho byujuje ibisabwa na NSF/ANSI 61 cyangwa WRAS kugira ngo hirindwe kwanduzwa.
Inzu yo hanze: Mu bidukikije bibi (urugero, aho gukorerwa imirimo yo hanze, aho inganda zikorera ivumbi cyangwa ubushuhe), hitamo metero zifite amanota ya IP (Ingress Protection) ya IP65 nibura (zidafata ivumbi kandi zikingiwe n'amazi adakoresha umuvuduko muto). Ku bikoresho bishobora gukoreshwa mu mazi (urugero, imiyoboro yo munsi y'amazi), koresha metero zifite amanota ya IP68. Mu bidukikije biturika (urugero, aho gutunganya peteroli), hitamo metero zifite icyemezo cya ATEX cyangwa IECEx ku hantu hashobora guteza akaga.

5. Gukumira no gukumira amashanyarazi adafite aho ahuriye n'ubutaka

Ibipimo bya EM bishobora kwangiza amashanyarazi, bishobora guhindura ikimenyetso no kugabanya ubuziranenge. Gushyiraho ubutaka neza ni ingenzi kugira ngo icyuma gipima urusaku rw'amashanyarazi rwo hanze:

Gushyira hasi icyuma gipima: Huza aho icyuma gipima ubutaka gihagarara ku butaka bwabugenewe kandi budakomeye (≤10Ω). Ntugasangire ubutaka n'ibindi bikoresho (urugero: moteri, pompe), kuko bishobora gutera urusaku. Ku miyoboro ya pulasitiki (idatwara amashanyarazi), shyiramo icyuma gipima ubutaka (icyuma gifatanye n'umuyoboro wo hejuru no munsi y'icyuma gipima) hanyuma ukijyane n'ubutaka bw'icyuma gipima ubutaka. Ibi bireba ko amazi ari ku bushobozi bumwe n'icyuma gipima ubutaka.
Gucunga insinga: Koresha insinga zikingira kugira ngo ubone ingufu n'amakuru (urugero: insinga za analog za 4-20mA, insinga za digitale za RS485). Kuramo insinga kure y'imirongo ifite voltage nyinshi (urugero: insinga z'amashanyarazi za 380V) n'amasoko ya electromagnetic (urugero: frequency drives zihindagurika, moteri) kugira ngo wirinde kubangamirana. Kuramo intera ya metero 1 nibura hagati y'insinga za EM meter n'insinga zifite urusaku rwinshi.

6. Uburyo bwo kugenzurwa no gupimwa

Ibipimo bya EM bisaba gusuzumwa buri gihe (urugero, gusukura electrode, gupima) kugira ngo bikomeze kuba byiza. Gushyira icyuma ahantu hatagerwa (urugero, ahantu hato ho gukurura, ibisenge birebire) byongera igihe n'ikiguzi cyo kugitunganya.

Tanga uburyo bwo kwinjira neza: Menya neza ko hari nibura metero 1 y'umwanya ukikije icyuma kugira ngo abatekinisiye bakore. Niba icyuma gishyirwa ku burebure, koresha urwego cyangwa urwego (rufite imiterere y'umutekano) kugira ngo ugereho.
Gushyiramo valve: Shyiramo valve zo kwitandukanya zijya hejuru no munsi y'icyuma gipima amazi. Izi valve zemerera abatekinisiye kuzimya amazi atembera kugira ngo bakomeze kuyakoresha cyangwa bayasimbuze batabujije inzira yose y'imiyoboro. Koresha valve zuzuye kugira ngo wirinde ko amazi atembera neza iyo ufunguye.
Ibitekerezo byo gupima: Hitamo ahantu horoshye guhuza ibikoresho byo gupima (urugero, ibipimo ngenderwaho by'amazi bigendanwa). Ku miyoboro minini, menya neza ko hari umwanya wo gushyiramo ibikoresho byo gupima by'agateganyo.

Umwanzuro

Gushyiraho neza ibipimo by'amazi akoreshwa mu ikoranabuhanga ni intambwe y'ingenzi mu gupima neza kandi yizewe mu miyoboro y'amazi. Mu gukemura uburebure bw'imiyoboro, guhuza ingano, kuzuza amazi, guhitamo ibikoresho, gushingira hasi, no kugerwaho, abakora bashobora kongera imikorere n'igihe cy'akazi k'ibipimo. Kwirengagiza ibi bintu ntibituma habaho amakuru atari yo gusa (ashobora kwangiza igenzura ry'imikorere cyangwa iyubahirizwa ry'amategeko) ahubwo binatuma ikiguzi cyo kubungabunga no gukora neza. Gufata umwanya wo gutegura no gushyira mu bikorwa neza bitanga ubwiza n'uburambe busabwa mu bikorwa bitandukanye by'inganda n'iby'umujyi.
