Ii-flowmeters ze-electromagnetic zinokufikelela ekulinganisweni nasekubekweni kweliso ngokuchanekileyo, kwaye zinokulinganisa noxinano lwezinto eziqinileyo kwi-lindle, zincede abasebenzi bendalo ukuba bajonge ngcono utshintsho lomgangatho wamanzi kunye neziphumo zonyango lwamanzi.
Ishishini Lokutya Neziselo: Ii-flowmeters ze-electromagnetic zikwasetyenziswa kakhulu kwishishini lokutya neziselo. Kwinkqubo yokuvelisa ukutya neziselo, ukuhamba nomgangatho wolwelo kufuneka kulinganiswe ukuqinisekisa uzinzo nokhuseleko lwenkqubo yokuvelisa. I-flowmeter ye-electromagnetic ine-characteristic and stability ephezulu, kwaye inokufikelela ekulinganisweni ngokuchanekileyo kokuhamba kolwelo nomgangatho, ngaloo ndlela iqinisekisa umgangatho nokhuseleko lwemveliso yokutya neziselo.
Ishishini legesi: Kwishishini legesi, ii-electromagnetic flowmeters nazo zisetyenziswa kakhulu. Umzekelo, kwinkqubo yokulinganisa igesi, ukuthuthwa kunye nokugcinwa kwayo, ukuhamba kwegesi kufuneka kulinganiswe ngokuchanekileyo kwaye kubekwe esweni. I-electromagnetic flowmeter inokufikelela ekulinganisweni ngokuchanekileyo kokuhamba kwegesi kwaye inokulinganisa ukuhamba kwegesi kwicala elinye okanye kwicala elinye njengoko kufuneka.
Ngamafutshane, ukuveliswa kwe-electromagnetic flowmeter kuzise iintsingiselo ezininzi ezilungileyo kumashishini ahlukeneyo. Ukuchaneka kwayo okuphezulu kokulinganisa, ukuzinza kunye nokuthembeka kunokuhlangabezana neemfuno zokulinganisa ukuhamba kweendawo ezahlukeneyo zoshishino kwaye kuqinisekise uzinzo kunye nokhuseleko lwenkqubo yemveliso.
