1) I-electromagnetic flowmeter ifuna umbhobho othe tye omfutshane kune-ultrasonic flowmeter. Indawo yokufaka i-electromagnetic flowmeter isenokungabi yi-straight pipe, ngoko thelekisa kwindawo yesiganeko, qwalasela indawo yokulinganisa ukuba ingaba iyahlangabezana na neemfuno ze-straight pipe ultrasonic flowmeter, ukuba ayihlangabezani nombhobho othe tye kufuneka ube kufutshane khetha ihambelana nendawo yomlinganiselo we-ultrasonic flowmeter, uthelekiso iziphumo aziyi kuba zichanekile.
2) Jonga ukuba indawo yokufaka i-flowmeter ye-electromagnetic iyahlangabezana na neemfuno zokuhamba kolwelo (ezifana nokuqhuba kolwelo, nokuba ukufakwa kukwindawo esezantsi yombhobho, nokuba amaqamza anokuqokelelana, njl.njl.). Ukuba akunjalo, kufuneka kucetyiswe kumsebenzisi ukuba oku kusenokuba yimbangela yengxaki.
3) I-electromagnetic flowmeter sisixhobo esilungileyo sokulinganisa ukuhamba kolwelo oluqhubayo. Ukuchaneka kwayo kokulinganisa kuphezulu kakhulu, ngokubanzi kwi-0.5%, kwaye kungcono ukufikelela kwi-0.2%. Kwangaxeshanye, kufuneka kunikwe ingqalelo kumenzi we-electromagnetic flowmeter. Ukuba imveliso yophawu ifakelwe ngaphandle kwempazamo kwaye i-liquid conductivity iyahlangabezana neemfuno, ixabiso lokulinganisa kufuneka likrokrelwe ngononophelo, ngelixa kubavelisi abangengobantu baqhelekileyo, ngokwezinga lozinzo lwentsimi ye-electromagnetic kunye nobukhulu bempazamo, unokuba nesibindi sokungabaza.
4) Qonda imeko yezinto ezisetyenziswayo kumbhobho, nokuba kukho ulwelo, umlinganiselo kunye nezinye izinto kunye neeparamitha ezinxulumene nombhobho ezivela kumsebenzisi. Polisha umbhobho xa ufaka i-ultrasonic sensor, kwaye ukhethe indlela ye-Z yokulinganisa nokuthelekisa kangangoko kunokwenzeka.
5) Ulwelo olunokulinganiswa yi-ultrasonic flowmeter aluchaphazeleki yi-conductivity. Ukuba ixabiso le-ultrasonic lizinzile ngelixa ixabiso le-electromagnetic lingazinzanga ngexesha lokuthelekisa, oko kubonisa ukuba i-conductivity yomzimba we-flow elinganiswayo ikwimeko yomda we-index, kunokuba ibangelwe yi-fluid containing gas, kwaye ixabiso le-ultrasonic flowmeter liyathembeka. Ukuba zombini azizinzanga ngaxeshanye, amathuba okuba kubekho amaqamza aphezulu.
6) Iimfuneko ze-electromagnetic flowmeter eziza kulinganiswa ulwelo kufuneka zilingane namandla omhlaba, kungenjalo kuya kubakho umlinganiselo wokuphazamiseka okunamandla, ngoko ke xa umhlaba ungachanekanga okanye ungachanekanga (umhlaba we-electromagnetic grounding uneemfuno ezintsonkothileyo nezingqongqo), kuya kubakho iingxaki, kufuneka ujonge imeko yomhlaba. Xa kuthelekiswa ne-ultrasonic flowmeter, akukho mfuneko enokubakho yolwelo. Ukuba umhlaba ungaqinisekanga, ixabiso le-ultrasonic flowmeter lichanekile.
7) Ukuba kukho ukuphazamiseka kweendawo zombane kunye nemagnethi ezikufutshane, impembelelo ye-ultrasonic flowmeter ingaphantsi kuneye-electromagnetic flowmeter, kwaye ukuthembeka kwexabiso lokubonisa le-ultrasonic kufuneka kube ngaphezulu kunele-electromagnetic flowmeter.
8) Ukuba kukho umthombo wesandi ophazamisayo kumbhobho (njengesandi esiveliswa yivalvu enkulu yokulawula uxinzelelo oluhlukeneyo), impembelelo kwi-ultrasonic inkulu kakhulu kuneyo kwi-electromagnetic, kwaye ukuthembeka kwexabiso lesibonakaliso se-electromagnetic kukhulu kunelo le-ultrasound.
