1) I-electromagnetic flowmeter idinga ipayipi eliqondile elifushane kune-ultrasonic flowmeter. Indawo yokufaka i-electromagnetic flowmeter kungenzeka ingasasebenzi ipayipi eliqondile, ngakho qhathanisa endaweni yesehlakalo, naka indawo yokulinganisa ukuthi ingahlangabezana yini nezidingo ze-ultrasonic flowmeter, uma ingahlangabezani nepayipi eliqondile kufanele libe seduze khetha ihambisana nendawo ye-ultrasonic flowmeter, ukuqhathanisa imiphumela ngeke kube okulungile.
2) Hlola ukuthi indawo yokufaka ye-flowmeter ye-electromagnetic iyahlangabezana yini nezidingo zokugeleza koketshezi (njengokuqhutshwa koketshezi, ukuthi ukufakwa kusesikhundleni esiphansi sepayipi, ukuthi amabhamuza anganqwabelana yini, njll.). Uma kungenjalo, kufanele kuphakanyiswe kumsebenzisi ukuthi lokhu kungaba yimbangela yenkinga.
3) I-electromagnetic flowmeter iyithuluzi elihle lokukala ukugeleza koketshezi oluqhubayo. Ukunemba kwayo kokulinganisa nakho kuphakeme kakhulu, ngokuvamile ku-0.5%, futhi kungcono ukufinyelela ku-0.2%. Ngesikhathi esifanayo, kufanele kunakwe umenzi we-electromagnetic flowmeter. Uma umkhiqizo womkhiqizo ufakwe ngaphandle kwephutha futhi uketshezi luhambisana nezidingo, inani lokulinganisa kufanele lisolwe ngokucophelela, kuyilapho kubakhiqizi abangebona abajwayelekile, ngokuya ngokuqina kwenani lensimu ye-electromagnetic kanye nosayizi wephutha, ungaba nesibindi sokungabaza.
4) Qonda isimo sezinto zepayipi, ukuthi ngabe kukhona ungqimba, usayizi nezinye izinto kanye nemingcele ehlobene yepayipi evela kumsebenzisi. Pholisha ipayipi uma ufaka inzwa ye-ultrasonic, bese ukhetha indlela ye-Z yokulinganisa nokuqhathanisa ngangokunokwenzeka.
5) Uketshezi olungalinganiswa nge-ultrasonic flowmeter aluthintwa yi-conductivity. Uma inani le-ultrasonic lizinzile kuyilapho inani le-electromagnetic lingazinzile ngesikhathi sokuqhathaniswa, kubonisa ukuthi i-conductivity yomzimba wokugeleza olinganiswayo isesimweni somngcele we-index, kunokuba ibangelwe uketshezi oluqukethe igesi, futhi inani le-ultrasonic flowmeter liyathembeka. Uma kokubili kungazinzile ngesikhathi esisodwa, amathuba okuba namabhamuza makhulu.
6) Izidingo ze-flowmeter kagesi okufanele zilinganiswe uketshezi kumele zibe namandla alinganayo nomhlaba, ngaphandle kwalokho kuzoba nokulinganisa okunamandla kokuphazamiseka, ngakho-ke lapho isisekelo singalungile noma isisekelo sibi (isisekelo se-electromagnetic sinezidingo eziyinkimbinkimbi neziqinile), kuzoba nezinkinga, kufanele uhlole isimo sesisekelo. Uma kuqhathaniswa ne-flowmeter ye-ultrasonic, akukho mfuneko engaba khona yoketshezi. Uma isisekelo singabazeka, inani le-flowmeter ye-ultrasonic lilungile.
7) Uma kukhona ukuphazamiseka kwamasimu kagesi namagnetic eduze, ithonya le-ultrasonic flowmeter lingaphansi kwele-electromagnetic flowmeter, futhi ukuthembeka kwenani lokubonisa le-ultrasonic kufanele kube kukhulu kunele-electromagnetic flowmeter.
8) Uma kukhona umthombo womsindo ophazamisayo epayipini (njengomsindo okhiqizwa yi-valve enkulu elawula ingcindezi ehlukile), ithonya ku-ultrasonic likhulu kakhulu kunele-electromagnetic, futhi ukuthembeka kwenani lesibonakaliso se-electromagnetic likhulu kunele-ultrasonic.
