1) I-electromagnetic flowmeter idinga ipayipi eliqondile elifushane kune-ultrasonic flowmeter's.Indawo yokufaka i-electromagnetic flowmeter ingase ingabe isaba ipayipi eliqondile, ngakho-ke qhathanisa endaweni yesehlakalo, naka indawo yokulinganisa ukuthi ingahlangabezana yini nezidingo zepayipi eliqondile le-ultrasonic flowmeter, uma lingahlangabezani nepayipi eliqondile kufanele libe seduze, khetha livumelana nendawo isilinganiso se-flowmeter ye-ultrasonic, ukuqhathanisa imiphumela ngeke ilunge.
2) Hlola ukuthi indawo yokufaka i-electromagnetic flowmeter iyahlangabezana yini nezidingo zokugeleza koketshezi (njengokuhamba koketshezi, noma ngabe ukufakwa kusendaweni engezansi yepayipi, noma amabhamuza anganqwabelana, njll.).Uma kungenjalo, kufanele kuphakanyiswe kumsebenzisi ukuthi lokhu kungaba imbangela yenkinga.
3) I-Electromagnetic flowmeter iyithuluzi elihle lokukala ukugeleza koketshezi olusebenzayo.Ukunemba kokulinganisa kwayo nakho kuphezulu kakhulu, ngokuvamile ku-0.5%, futhi kungcono kakhulu ukufinyelela ku-0.2%.Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe kumenzi we-electromagnetic flowmeter.Uma umkhiqizo womkhiqizo ufakwe ngaphandle kwephutha futhi i-conductivity yoketshezi ihlangabezana nezidingo, inani lokulinganisa kufanele lisolwe ngokucophelela, kanti kubakhiqizi abangebona abajwayelekile, ngokuya ngenani lensimu ye-electromagnetic ukuzinza nosayizi wephutha, ungaba nesibindi sokungabaza.
4) Qonda isimo sempahla yepayipi, noma ngabe kukhona ulayini, ukukala nezinye izenzakalo kanye nemingcele ehlobene yepayipi elivela kumsebenzisi.Pholisha ipayipi lapho ufaka inzwa ye-ultrasonic, bese ukhetha indlela engu-Z yokulinganisa nokuqhathanisa ngangokunokwenzeka.
5) Uketshezi olungalinganiswa yi-flowmeter ye-ultrasonic aluthintwa yi-conductivity.Uma inani le-ultrasonic lizinzile kuyilapho inani le-electromagnetic lingazinzile ngesikhathi sokuqhathaniswa, libonisa ukuthi ukuqhutshwa komzimba okugelezayo okulinganiswayo kusesimweni somngcele wenkomba, kunokuba kubangelwe uketshezi oluqukethe igesi, kanye nenani le-ultrasonic. i-flowmeter ithembekile.Uma zombili zingazinzile ngesikhathi esisodwa, amathuba okuba amabhamuza makhulu.
6) Izidingo ze-electromagnetic flowmeter ukuze zikalwe uketshezi kumele zibe namandla alinganayo nomhlaba, ngaphandle kwalokho kuzoba nesilinganiso esiqinile sokuphazanyiswa, ngakho-ke lapho isisekelo singalungile noma sibi (isisekelo somagnetic sinezidingo eziyinkimbinkimbi neziqinile), kuzoba nezinkinga. , kufanele ahlole isimo sokumisa.Uma kuqhathaniswa ne-flowmeter ye-ultrasonic, asikho isidingo esingaba khona soketshezi.Uma isisekelo singabazekayo, inani le-flowmeter ye-ultrasonic lilungile.
7) Uma kukhona ukuphazamisa kwezindawo zikagesi nezikazibuthe eziseduze, ithonya le-flowmeter ye-ultrasonic lingaphansi kwalelo le-electromagnetic flowmeter, futhi ukwethembeka kwevelu yokubonisa ye-ultrasonic kufanele ibe nkulu kunaleyo ye-electromagnetic flowmeter.
8) Uma kunomthombo womsindo ophazamisayo epayipini (njengomsindo okhiqizwa ivalve enkulu elawula ingcindezi ehlukanisayo), ithonya ku-ultrasonic likhulu kakhulu kunalelo elitholakala ku-electromagnetic, futhi ukwethembeka kwevelu yenkomba ye-electromagnetic kukhulu kunaleyo. kwe-ultrasonic.
