Yikuphi ukwehluleka okuzokwenzeka ngesikhathi sokulungisa iphutha le
i-plug-in flowmeter ye-electromagnetic, uhlobo lokuhlukanisa i-electromagnetic flowmeter kanye nokwehluleka kwasekuqaleni kokususa iphutha, kodwa uma ukwehluleka sekuthuthukisiwe, ngokuvamile ngeke kuphinde kwenzeke ngaphansi kwezimo ezifanayo. Amaphutha ajwayelekile abangelwa ikakhulukazi isikhathi sokufakwa nesokugunyazwa, ukuphazamiseka kwemvelo, kanye nomthelela wezimpawu zoketshezi. Izizathu ezintathu.
Ukufakwa kwesistimu yamapayipi, njll., indawo evamile yokufaka inzwa ye-electromagnetic flow ayilungile. Isibonelo, inzwa yokugeleza ifakwe kunethiwekhi yepayipi yegesi yemvelo okulula ukunqwabelana. Inzwa yokugeleza ayinakho ukucindezela, futhi uketshezi lukhishelwa ngokuqondile emkhathini ukuze lwenza isilinganiso esiphelele. Ipayipi; efakwe emgqeni oqondile ngenxa yokungcola, ingase ibonakale ingenalutho, ukufakwa kwemitha yokugeleza kukhethekile, ngenxa yamandla angaphansi kwamanzi ukuze kuqinisekiswe ukuthi akukho okuntantayo.
Indawo ezungezile, ukuphazamiseka kwamanje kwepayipi elikhulu elinhlanhlathayo, ukuphazamiseka kukazibuthe esikhaleni, ukuphazamiseka kwenjini enkulu kazibuthe, nokunye ukuphazamiseka kwamanje kwamapayipi ngokuvamile kuthatha ukuvikeleka okuhle komhlaba kungakalwa ngokwehlukana ngendlela egculisayo, kodwa endabeni yamapayipi anamanzi azulazulayo anamandla (njengokuhlangana ulayini wendawo yokusebenzela ye-electrolysis awukwazi ukunqotshwa, futhi izinyathelo eziyingqayizivele kufanele zithathwe ngenzwa yokugeleza kanye nonqenqema lwepayipi Ukwethulwa kwekhebula lesignali ye-electromagnetic wave-space, ngokuvamile ukuvikela okukodwa noma okuningi, kodwa futhi okuhlangatshezwane nokuvikelwa kokuvikela akukwazi ukunqotshwa.
Uketshezi oluqukethe amabhamuza amancane ngokuvamile lusakazwa ngokulinganayo futhi akuthinti ukulinganisa okuvamile. Uketshezi lokugeleza kwevolumu kuphela kanye negesi kuhlangene; amabhamuza azokwandisa ukuguquguquka kwesiginali yokuphumayo. Uma amabhamuza amakhulu emboza yonke indawo ye-electrode egeleza ku-electrode, isignali ye-electrode izonqanyulwa khona manjalo Circuit, isignali yokuphumayo izoveza ukushintshashintsha okukhulu.
imvamisa ephansi (50/16 Hz-50/6 Hz) ukuhlukaniswa kwegagasi elingunxande
i-electromagnetic flowmeterizokhipha umsindo lapho uketshezi luqukethe okuqinile okwedlula okuqukethwe okuthile kodaka, futhi isignali yokuphumayo nayo izoguquguquka ngokwezinga elithile.
