Mu kayendetsedwe ka madzi a mafakitale, kulondola ndi kugwira ntchito bwino sikungakambiranedwe—komanso kuwongolera ndalama kwa nthawi yayitali. Pa ntchito kuyambira m'malo oyeretsera madzi mpaka malo opangira mankhwala, kufunafuna zida zoyezera zomwe zimalinganiza kulondola ndi kusamalitsa pang'ono kwapangitsa ambiri kupeza njira yosinthira zinthu: mita yoyezera madzi yamagetsi yotsika (EMFs). Mosiyana ndi mita yoyezera madzi yachikhalidwe yomwe imadalira zinthu zosuntha zomwe zimatha kusweka, kutsekeka, kapena dzimbiri, zida zapamwambazi zimagwiritsa ntchito Lamulo la Faraday la kuyambitsa magetsi kuti zipereke deta yodalirika—ponseponse pochepetsa nthawi yokonza, ndalama zogwirira ntchito, komanso nthawi yopuma yosakonzedwa. Masiku ano mafakitale othamanga, ma EMF osakonza magetsi si njira yophweka chabe; ndi njira yabwino yogwiritsira ntchito bwino ntchito.
Pakati pa kufunika kwa ma EMF osasamalidwa bwino pali kapangidwe kawo kosalowerera, kopanda mbali. Ma flow meter achikhalidwe, monga ma turbine kapena ma positive displacement models, amagwiritsa ntchito zigawo zozungulira kapena zotchinga zakuthupi kuti ayesere kuyenda kwa madzi. Pakapita nthawi, zigawozi zimawonongeka chifukwa cha kukangana, kukhudzana ndi madzi owononga kapena owononga (monga madzi otayirira okhala ndi zinyalala, mankhwala osungunuka), kapena kuchuluka kwa zinthu zodetsa monga sikelo kapena matope. Kuwonongeka kumeneku kumakakamiza kuwunika pafupipafupi, kusintha magawo, ndi kuwerengera - njira zokwera mtengo zomwe nthawi zambiri zimafuna kutseka dongosolo lonse. Ma EMF osasamalidwa bwino, mosiyana, alibe zigawo zosuntha. M'malo mwake, ali ndi chubu cha sensor chokhala ndi zinthu zosagwira dzimbiri (monga PTFE, rabara) ndi ma coil awiri amagetsi. Madzi akamadutsa mu chubu, ma coil amapanga mphamvu ya maginito, ndipo ma electrode amazindikira mphamvu yamagetsi yomwe imachitika chifukwa cha kuyenda kwa madzi - kuwerengera mwachindunji kuchuluka kwa madzi popanda kukhudzana ndi thupi. Kapangidwe kameneka kamachotsa chiopsezo cha kulephera kwa magawo, kutsekeka, kapena kuwonongeka kwa makina, zomwe zimachepetsa kwambiri kufunikira kokonza nthawi zonse. Mwachitsanzo, pa fakitale yoyeretsera madzi ya boma, izi zikutanthauza kupewa kutsekedwa mwezi uliwonse kuti ayeretse mita ya turbine; m'malo mwake, EMF imagwira ntchito mosalekeza, ndi macheke owunikira pachaka okha omwe amafunika.
Kupatula kuchepetsa ntchito yokonza, ma EMF osakonza bwino amayendetsa bwino ndalama chifukwa cha kulimba komanso kusinthasintha. Kapangidwe kawo kolimba—kuphatikizapo nyumba zosapanga dzimbiri ndi ma liners osagwiritsa ntchito mankhwala—kumatsimikizira kuti amapirira malo ovuta a mafakitale, kuyambira ku malo oyeretsera mafuta otentha kwambiri mpaka ntchito zofukula mafuta acidic. Mosiyana ndi ma mita amakina omwe angafunike kusinthidwa kwathunthu zaka 2-3 zilizonse, EMF yosamalidwa bwino imatha kukhala zaka khumi kapena kuposerapo, kuchepetsa nthawi yogwiritsira ntchito ndalama. Kuphatikiza apo, kuthekera kwawo kuyeza madzi osiyanasiyana—kuyambira zakumwa zoyendetsa (madzi, mankhwala) mpaka slurry zokhuthala (simenti, ma phala a chakudya)—kumachotsa kufunikira koyika ndalama m'mitundu yosiyanasiyana ya mita pazinthu zosiyanasiyana. Wopanga chakudya ndi zakumwa, mwachitsanzo, angagwiritse ntchito EMF yofanana yosakonza bwino kuti ayang'anire kayendedwe ka madzi m'mabotolo ndi kutulutsa madzi otayira, kupewa mtengo wa ma mita apadera pa ntchito iliyonse. Kusinthasintha kumeneku sikungopangitsa kuti kasamalidwe ka zinthu kakhale kosavuta komanso kumachepetsa nthawi yophunzitsira antchito, omwe amangofunika kuphunzira momwe chipangizo chimodzi chimagwirira ntchito.
Chofunika kwambiri n'chakuti, ma EMF osasamalidwa bwino sawononga kulondola kwa muyeso kuti zinthu ziyende bwino—nkhawa yofunika kwambiri kwa mafakitale komwe deta yolondola ya kayendedwe ka madzi imakhudza mwachindunji ubwino wa zinthu, kutsatira malamulo, komanso kukonza bwino zinthu. Ukadaulo wawo wamagetsi umapereka kulondola kwa ± 0.5% mpaka ± 1% ya kuchuluka kwa madzi, ngakhale m'mikhalidwe yosinthasintha kapena pamene madzi ali ndi zinthu zolimba zomwe zimayimitsidwa. Pa fakitale ya mankhwala yosakaniza zinthu zopangira, kulondola kumeneku kumatsimikizira kusinthasintha kwa mafuta, kuchepetsa zinyalala kuchokera ku kuchuluka kapena kuchepa kwa mlingo. Pa ntchito zamafuta ndi gasi, zimathandiza kutsatira molondola kusamutsa mafuta, kupewa kutayika kwa ndalama kuchokera ku zolakwika zoyezera. Kuphatikiza apo, ma EMF ambiri amakono osasamalidwa bwino amaphatikizapo zinthu zanzeru monga zowonetsera za digito, luso loyang'anira kutali, ndi machenjezo odzidziwitsa okha. Zidazi zimalola ogwira ntchito kutsatira deta ya kayendedwe ka madzi nthawi yeniyeni, kuzindikira mavuto omwe angakhalepo (monga, kuchuluka kwa madzi osazolowereka) asanafike pamlingo wapamwamba, ndikuchita ma calibration enieni—kuchepetsanso nthawi yogwira ntchito. Wopanga mankhwala, mwachitsanzo, angagwiritse ntchito kuyang'anira kutali kuti atsimikizire kuti madzi osasamalidwa akutsatira miyezo ya FDA 24/7, popanda kutumiza akatswiri kuzipinda zoyera kuti akafufuze pafupipafupi.
Mu nthawi imene ntchito zamafakitale zikukumana ndi mavuto ambiri kuti achepetse ndalama, apititse patsogolo kukhazikika, ndikuwonjezera zokolola, ma electromagnetic flow meter osasamalidwa bwino amadziwika ngati njira yothandiza. Kapangidwe kawo kosagwiritsa ntchito nthawi zambiri kamachotsa nthawi yokonza yokwera mtengo, kulimba kwawo kumawonjezera nthawi ya moyo wa zida, kusinthasintha kwawo kumachepetsa ndalama zogulira, ndipo kulondola kwawo kumateteza khalidwe ndi kutsatira malamulo. Kwa oyang'anira mafakitale ndi magulu ogwirira ntchito, masamuwo ndi omveka bwino: kuyika ndalama mu EMF yosasamalidwa bwino sikungokhudza kugula flow meter - koma kumafuna ndalama mu nthawi yayitali yogwirira ntchito. Kaya zimagwiritsidwa ntchito pochiza madzi, kupanga, kapena kupanga mphamvu, zipangizozi zimatsimikizira kuti kugwiritsa ntchito bwino ndalama komanso luso loyeza zinthu kungayende limodzi - kusintha chida chachizolowezi kukhala choyendetsa bwino mafakitale.
