Izimiso zokukhetha.
Uketshezi oluzohlolwa kufanele lube uketshezi lokuqhuba noma i-sdrury ngokuqhuba okungaphansi kuka-50 μS / cm, futhi uketshezi oluzohlolwa akufanele luqukethe izinto eziningi ze-ferromagnetic noma amabhamuza.
Izinga lokucindezela elifanele, izinto zokugcina, izinto ze-electrode nezakhiwo zezinsimbi kufanele zikhethwe ngokuya ngezici zoketshezi okufanele zilinganiswe.
Ukukhetha Indlela
1. Ngoba i-electromagnetic flowmeter inobubanzi obuphezulu obungu-1500: 1, ububanzi bensimbi buvame ukufana naleyo yepayipi lenqubo.
2. Uma isilinganiso esilinganisiwe siqukethe izinhlayiya eziqinile, ibanga lokugeleza elinconywayo lingu-1 - 3 m / s. Uma izinga lokugeleza langempela likhulu kakhulu futhi akulungile ukushintsha, ububanzi bensimbi yokuzikhethela inkulu kunaleyo yepayipi lenqubo.
Ukunciphisa izinga lokugeleza koketshezi esigabeni sokulinganisa ipayipi lokugeleza kahle, inciphisa ukugqoka kwezinhlayiya ku-electrode nakulayini.
3. Uma kungahle kube khona ipayipi lenqubo, izinga lokugeleza okunconyiwe ngu-2-5 m / s. Uma izinga lokugeleza langempela lincane kakhulu futhi akulungile ukushintsha ipayipi lenqubo, insimbi yokuzikhethela enobubanzi obuncane
Ngokobubanzi bepayipi lenqubo, izinga lokugeleza koketshezi lwe-flowmeter lingakhuphuka ngokufanele ukugwema ithonya le-sedled ekunembeni kwemitha.
4. Lapho isilinganiso sokugeleza sincane kakhulu futhi kudingeka ukulinganisa okukhulu, inzwa encane kunobubanzi bepayipi lenqubo ingakhethwa ukukhulisa izinga lokugeleza nokuqinisekisa ukunemba okuphezulu.
Ezimweni ezingenhla ezingama-2, 3, no-4, abancishisi kufanele bafakwe phezulu komfula nasezansi komfula wokugeleza. I-engeli ye-cone emaphakathi yokunciphisa akufanele ibe nkulu kune-15 °, futhi okungenani kufanele kube nesigaba sepayipi eqondile enhla komfula wokunciphisa okuphindwe kahlanu ububanzi bepayipi lenqubo.
