Okokuqala, impembelelo ye-conductivity kwi-electromagnetic flowmeter
I-electromagnetic flowmeter sisixhobo sokulinganisa esisetyenziswa ekulinganiseni ukuhamba kolwelo kunye negesi. Ii-electromagnetic flowmeters zinemisebenzi yokulinganisa kuphela ulwelo okanye iigesi eziqhuba umbane. Kwimeko yokuqhuba kombane okungahambi kakuhle, ukusasazeka kwesignali kunokubangela ukuphazamiseka, okubangela iziphumo zokulinganisa ezingachanekanga. Ke ngoko, iimfuno zokuqhuba umbane kwii-electromagnetic flowmeters nazo zibaluleke kakhulu.
Okwesibini, iimfuno zokuqhuba kwe-electromagnetic flowmeters
Phantsi kweemeko eziqhelekileyo, iimfuno zokuqhuba kwe-electromagnetic flowmeter kufuneka zifikelele ngaphezu kwe-0.1S/m. Kuphela xa i-conductivity ifikelela ngaphezu kwe-0.1S/m, i-electromagnetic flowmeter inokubona kwaye ilinganise ngokufanelekileyo i-current kunye ne-magnetic field. Ukuba i-conductivity ingaphantsi kwe-0.1S/m, isignali yokukhupha ye-electromagnetic flowmeter iya kuba buthathaka, nto leyo ebangela ukwanda kwempazamo, kwaye kuya kwenzeka into enzulu yokutyibilika, eya kuchaphazela ngqo ukusetyenziswa kwe-electromagnetic flowmeter.
3. Iimfuno zokuqhuba umbane kwiimeko ezahlukeneyo zesicelo
Iigesi ezahlukeneyo kunye nolwelo zinee-conductivity ezahlukeneyo zombane, ngoko ke kwiimeko ezahlukeneyo zokusetyenziswa, iimfuno zokuqhuba ii-electromagnetic flowmeters nazo zahlukile. Umzekelo, kwi-sewage, i-pulp, i-asidi ye-lye, amanzi olwandle kunye nezinye izinto ezilulwelo kufuneka zifune i-conductivity engaphezulu kwe-0.1S/m; Kwigesi, ioyile, igesi yendalo kunye nezinye iigesi kufuneka zifune i-conductivity engaphezulu kwe-10^-6S/m. Kwiinkqubo ezisebenzayo, iimveliso ze-electromagnetic flowmeter ezifanelekileyo kufuneka zikhethwe ngokweemfuno zeemeko ezahlukeneyo, kwaye i-conductivity kufuneka ilungiswe ngokweemfuno.
Ngamafutshane, iimfuno zokuqhuba kwe-electromagnetic flowmeter kufuneka zifikelele ubuncinane kwi-0.1S/m2, kwaye kwiimeko ezahlukeneyo zokusetyenziswa, kukho iimfuno ezahlukeneyo zokuqhuba kwe-electromagnetic flowmeter. Ukuqonda ukuqhuba kwe-electromagnetic flowmeter kubaluleke kakhulu ekusetyenzisweni ngokuchanekileyo kwe-electromagnetic flowmeter.
