Iislurry, njengemixube eyinkimbinkimbi yolwelo kunye namasuntswana aqinileyo, ziyimfuneko kakhulu kumashishini afana nemigodi, ukucubungula iikhemikhali, unyango lwamanzi amdaka, kunye nokwakha. Ukulinganiswa ngokuchanekileyo kokuhamba kwamanzi kubalulekile ekwenzeni ngcono iinkqubo zemveliso, ukulawula iindleko, kunye nokuqinisekisa ukhuseleko lokusebenza. Phakathi kweendlela ezahlukeneyo zokulinganisa ukuhamba kwamanzi, ii-electromagnetic flowmeters (ii-EMF) zibalaseleyo ngeenzuzo zazo ezikhethekileyo ekusingatheni imingeni ebangelwa ziislurry ezirhabaxa, ezixineneyo, kunye neziqulathe izinto eziqinileyo eziphezulu.
Umgaqo wokusebenza kwee-EMF usekelwe kuMthetho kaFaraday wokungeniswa kwe-electromagnetic. Xa i-slurry eqhubayo idlula kwi-magnetic field eveliswa zii-coils zemitha, ibangela amandla e-electromotive (EMF) ahambelana nesantya sokuhamba, amandla e-magnetic field, kunye nomgama phakathi kwee-electrodes. Le voltage ebangelwayo ifunyanwa zii-electrodes ezifakwe eludongeni lombhobho, kwaye i-flowmeter iyiguqula ibe kukufundwa kwesantya sokuhamba esichanekileyo. Okuphawulekayo kukuba, ii-EMF zilinganisa isantya sokuhamba kwevolumu ngokuthe ngqo, zingachaphazeleki yi-slurry viscosity, uxinano, okanye utshintsho lobushushu—izinto eziphambili eziphazamisa ezinye iintlobo zemitha.
Inzuzo ephambili yee-EMFs kwizicelo ze-slurry kuyilo lwazo olungaphazamisiyo okanye olugcweleyo. Ii-EMFs ze-full-bore zinesakhiwo sepayipi esithe tye esingenazo iindawo ezishukumayo okanye izithintelo, nto leyo esusa umngcipheko wokuvaleka, ukuguguleka, okanye ukulahleka koxinzelelo okubangelwa ziinxalenye ze-slurry. Olu yilo luqinisekisa ukuhamba kwe-slurry okungaphazanyiswayo kwaye lunciphisa iimfuno zolondolozo, inzuzo ebalulekileyo kwi-slurry ezirhabaxa ezifana neentsila zemigodi okanye imixube yekhonkrithi eyonakalisa ngokulula ii-flowmeters zoomatshini.
Ii-EMF zikwabonakalisa ukuzivumelanisa kakuhle neempawu ezahlukeneyo ze-slurry. Zisebenza ngokuthembekileyo nge-slurry equlethe ulwelo oluqhubayo (umz., i-slurry esekwe emanzini) kunye namasuntswana aqinileyo anobukhulu obahlukeneyo, ukusuka kwi-sediment encinci ukuya kwi-aggregates erhabaxa. Iimodeli ze-EMF eziphambili zixhotyiswe ngee-electrodes ezimelana nokugqwala (ezenziwe ngezinto ezifana neHastelloy, titanium, okanye i-tantalum) kunye nee-liners (irabha, i-PTFE, okanye i-polyurethane), ezizivumela ukuba zikwazi ukumelana neemeko ezinzima ze-slurry, kubandakanya amaqondo obushushu aphezulu kunye nokugqwala kweekhemikhali.
Kwimisebenzi yemizi-mveliso, ii-EMF zisetyenziswa kakhulu kumacandelo okuphatha udaka. Kwimigodi, zijonga ukuhamba kodaka lwezimbiwa (umz., ubhedu, udaka lwesinyithi) ngexesha lokukhupha nokucubungula, ziqinisekisa ukuthuthwa kwe-ore ngokufanelekileyo kunye nolawulo lwenkqubo. Izityalo zonyango lwamanzi amdaka zisebenzisa ii-EMF ukulinganisa ukuhamba kodaka lwezimbiwa, zixhasa iinkqubo zokukhupha amanzi kunye nokulahla udaka ngelixa zithobela imithetho yokusingqongileyo. Kwishishini lokwakha, zilinganisa ngokuchanekileyo ukuhamba kodaka lwekhonkrithi ukugcina umlinganiselo wokuxuba kunye nokuqinisekisa umgangatho wesakhiwo.
Ukuze kuphuculwe ukuchaneka kokulinganisa, kufuneka kuqwalaselwe izinto ezininzi zokusebenza. I-slurry kufuneka ibe nokuqhuba okwaneleyo; i-slurry engaqhubiyo (umz., imixube esekwe kwioyile) ifuna ukulungiswa kwangaphambili okanye ezinye iimitha. Ukufakelwa ngokufanelekileyo, kubandakanya ubude obufanelekileyo bemibhobho ethe tye phezulu/ezantsi, kuthintela ukuphazamiseka kokuhamba kwamanzi. Ukugcinwa rhoqo, okufana nokucoca ii-electrode kunye nokuhlola ii-liners ukuba azigugi, kugcina ukuthembeka kokulinganisa. Ukulinganisa ngokweendlela eziqhelekileyo (umz., iitanki ze-volumetric) kuyacetyiswa nakwiinkqubo ezibalulekileyo.
Njengoko amashishini elandela ukusebenza kakuhle nokuchaneka okuphezulu, ii-EMF ziyaqhubeka nokukhula ngetekhnoloji ezikrelekrele, ezinje ngokucubungula imiqondiso yedijithali kunye nokudluliselwa kwedatha engenazingcingo, ukuphucula ukujonga ngexesha langempela kunye nokukwazi ukulawula kude. Ukukwazi kwazo ukusingatha iimeko ezinzima zokudaka, kunye nokuchaneka okuphezulu kunye nokugcinwa okuncinci, kwenza ii-flowmeters ze-electromagnetic zibe sisixhobo esibalulekileyo sokulinganisa ukuhamba kodaka lwanamhlanje, ziqhuba ukugqwesa kokusebenza kumacandelo aphambili emizi-mveliso.
