Ii-electromagnetic flowmeters (EMFs) zaziwa kakhulu ngokuchaneka kwazo okuphezulu, ukulinganisa okungaphazamisiyo, kunye nokuhambelana kwazo noluhlu olubanzi lwe-conductive fluids—ukusuka kumanzi acocekileyo ukuya kwiikhemikhali zoshishino ezirhabaxa. Njengezinto ezibalulekileyo kulawulo lwenkqubo, ulawulo lwemithombo yamanzi, kunye neenkqubo zonyango lwamanzi amdaka, ukusebenza kwazo okuthembekileyo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokusebenza kakuhle kweendleko. Nangona kunjalo, njengazo zonke izixhobo zoshishino, ii-EMFs zifuna ukulungiswa ngokufanelekileyo ukuze ziphucule ubomi bazo benkonzo, obuhlala buphakathi kweminyaka eli-10 ukuya kweli-15 ngononophelo olufanelekileyo. Ngezantsi kukho iingcebiso ezibalulekileyo zokulungisa ukukunceda ugcine ii-electromagnetic flowmeters zakho zikwimeko entle kwaye zandise ubomi bazo bokusebenza.
Okokuqala nokubalulekileyo, jonga rhoqo izinto zangaphandle ze-flowmeter. Indlu ye-sensor kunye ne-transmitter, uqhagamshelo lweentambo, kunye neenkqubo zokumisa umhlaba zisengozini yokonakala kwendalo, ukungcangcazela, kunye nokuguguleka. Hlola indlu ukuba ayinamabala, ukugqwala, okanye iimpawu zokungena kwamanzi, ingakumbi kwiindawo ezinzima zoshishino okanye zangaphandle. Qinisekisa ukuba ii-cable glands ziqinile kwaye izitywino azinakonakala ukuthintela umswakama ukuba ungangeni kwi-elektroniki—ukufuma yenye yezona zinto ziphambili zokungaphumeleli kwe-transmitter. Ukongeza, jonga uqhagamshelo lokumisa umhlaba rhoqo; ukumisa umhlaba ngokufanelekileyo kubalulekile ukuze kuchaneke i-EMF kwaye kukhuseleke kuphazamiseko lombane. Iingcingo zomhlaba ezikhululekileyo okanye ezigqwalileyo zinokukhokelela kwiimpazamo zokulinganisa kunye nomonakalo kwiisekethe zangaphakathi, ngoko ke coca kwaye uqinise uqhagamshelo njengoko kufuneka.
Ukucocwa ngokufanelekileyo kwetyhubhu yesensor yenye into ebalulekileyo yokulungisa. Ekuhambeni kwexesha, ulwelo oluqhubayo olunezimbiwa ezixhonyiweyo, udaka, okanye iiminerali zinokuqokelelana eludongeni lwangaphakathi lwetyhubhu yesensor, zenze ulwelo oluchaphazela ukuchaneka kokulinganisa kwaye ekugqibeleni lunokubangela ukungasebenzi kakuhle kwesensor. Ubuninzi bokucoca buxhomekeke kuhlobo lolwelo: kumanzi amdaka okanye ulwelo olunomxholo ophezulu oqinileyo, ukucoca rhoqo ngenyanga okanye rhoqo ngekota kunokufuneka, ngelixa ukusetyenziswa kwamanzi acocekileyo kunokufuna ukucocwa rhoqo ngonyaka. Xa ucoca, soloko ulandela izikhokelo zomenzi: cima ukuhamba kwamanzi, yahlula i-flowmeter, kwaye usebenzise iiarhente zokucoca ezifanelekileyo ukuze ungonakalisi i-electrode kunye nezinto ze-liner. Umzekelo, ziphephe izicoci ezirhabaxa kwii-liner ezithambileyo ezifana nerabha, kwaye usebenzise izisombululo ezingabolisiyo kwii-electrode zentsimbi engagqwaliyo. Ungaze ukrwele umphezulu we-electrode, kuba oku kunokuphazamisa intsimi ye-electromagnetic kwaye kuphazamise ukusebenza kokulinganisa.
Ukuqinisekiswa kokulinganiswa kubalulekile ukuze kugcinwe ukuchaneka kokulinganisa nokuqinisekisa ukuthotyelwa kwemigangatho yoshishino. Kwanee-EMF ezigcinwe kakuhle zinokuhamba kancinci ngokuhamba kwexesha ngenxa yotshintsho lokusingqongileyo, iimpawu zolwelo, okanye ukuguga kwenxalenye. Kucetyiswa ukuqinisekisa ukulinganiswa minyaka le, okanye rhoqo kwizicelo ezibalulekileyo ezifana nokucubungula iikhemikhali okanye ukujonga ukuthobela imithetho. Ukulinganiswa kungenziwa kwindawo kusetyenziswa izixhobo zokulinganisa eziphathekayo okanye ngokuthumela i-flowmeter kwilebhu eqinisekisiweyo. Ngexesha lokulinganiswa, jonga inqaku le-zero, ukuchaneka kwesikali esipheleleyo, kunye nokuhambelana kwe-curve yokulinganisa. Nakuphi na ukuphambuka kufuneka kulungiswe ngokukhawuleza ukuqinisekisa ukukhutshwa kwedatha okuthembekileyo.
Jonga kwaye ugcine inkqubo yombane ye-flowmeter. Umbane we-transmitter, iibhodi zesekethe, kunye neepaneli zokubonisa zifuna ukuhlolwa rhoqo ukuze kufunyanwe iingxaki ezinokubakho kwangethuba. Qinisekisa ukuba umbane uzinzile kwaye ungaphakathi koluhlu oluchaziweyo lomenzi—ukuguquguquka kwe-voltage kunokonakalisa izixhobo ze-elektroniki ze-transmitter. Hlola iibhodi zesekethe ukuze ubone iimpawu zobushushu obuphezulu, ezinje ngokutshintsha kombala okanye izinto ezitshileyo, kwaye ujonge iphaneli yokubonisa ukuze ubone ukuba icacile kwaye isebenza kakuhle. Kwi-EMFs ezikrelekrele ezinezakhono ze-IoT, qinisekisa ukuba iimodyuli zonxibelelwano zisebenza ngokufanelekileyo kwaye i-firmware ihlaziywa rhoqo. Uhlaziyo lwe-Firmware luhlala luquka ukulungiswa kweempazamo, ukuphuculwa kokusebenza, kunye neempawu ezintsha eziphucula ukuthembeka nokusebenza kwe-flowmeter.
Okokugqibela, sebenzisa inkqubo ebanzi yokugcinwa kwerekhodi. Bhala phantsi yonke imisebenzi yokugcinwa kwerekhodi, kuquka ukuhlolwa, ukucoca, ukulinganiswa, ukulungiswa, kunye nokutshintshwa kwamacandelo. Bhala phantsi ulwazi oluphambili olufana nomhla wokugcinwa kwerekhodi, umntu owenza umsebenzi, naziphi na iingxaki ezifunyenweyo, kunye namanyathelo athathiweyo. Le nkqubo yokugcinwa kwerekhodi inceda ukulandelela ukusebenza kwe-flowmeter ngokuhamba kwexesha, ichonge iingxaki eziphindaphindayo, kwaye icwangcise imisebenzi yokukhusela ukugcinwa kwerekhodi ngokufanelekileyo. Ikwabonelela ngedatha ebalulekileyo yokusombulula iingxaki, amabango ewaranti, kunye nokuphuculwa kwezixhobo kwixesha elizayo.
Ukuqukumbela, ukugcinwa kwangaphambili nangokucwangcisiweyo yeyona nto iphambili ekwandiseni ubomi benkonzo yee-flowmeters ze-electromagnetic. Ngokuqhuba uhlolo lwangaphandle rhoqo, ukucoca ngokufanelekileyo, ukuqinisekiswa kokulinganiswa, ukujonga inkqubo yombane, kunye nokugcina iirekhodi ezineenkcukacha, unokuqinisekisa ukuba ii-EMF zakho zibonelela ngokusebenza ngokuchanekileyo nangokuthembekileyo kwiminyaka ezayo. Ukutyala ixesha kunye nezixhobo kulondolozo akunciphisi nje kuphela umngcipheko wexesha lokungasebenzi elingalindelekanga kunye nokulungiswa okubiza kakhulu kodwa kwandisa imbuyekezo kutyalo-mali lwakho kwizixhobo zokulinganisa ukuhamba. Soloko ubhekisa kwincwadi yolondolozo yomenzi ukuze ufumane izikhokelo ezithile ezenzelwe imodeli yakho ye-flowmeter kunye nokusetyenziswa kwayo.
