I-electromagnetic flowmeter sisixhobo esisetyenziselwa ukulinganisa ukuhamba kolwelo oluqhubayo.
Ngokungafaniyo nee-flowmeters zemveli, ii-electromagnetic flowmeters zisebenza ngokusekwe kumthetho kaFaraday wokungeniswa kwe-electromagnetic kunye nokulinganisa ukuhamba kolwelo oluqhubayo olusekwe kumandla ombane oveliswayo xa ulwelo oluqhubayo ludlula kwindawo yangaphandle yamagnetic.
Ulwakhiwo lwe-electromagnetic flowmeter ikakhulu lunenkqubo yesekethe yamagnetic, umjelo wokulinganisa,i-electrodes, indlu, i-lining, kunye nesiguquli.
Ingaba isebenza kanjani?
1. Imveliso yemagnethi
Xa i-flowmeter isetyenziswa, i-coil ye-electromagnetic ivelisa indawo yemagnethi ejonge kwicala lokuhamba kolwelo. Le ntsimi yamagnetic izinzile kwaye ifana, iqinisekisa iziphumo ezihambelanayo zokulinganisa.
2. Ukungeniswa kombane
Xa i-conductive liquide inqumla kwi-magnetic field, inqumla imigca yemagnethi. Ngokomthetho kaFaraday, le ntshukumo ibangela i-voltage kulwelo. Ubukhulu balo mbane bulingana nesantya sokuhamba kolwelo.
3. Ukufunyanwa kwamandla ombane
I-Electrodes efakwe kwityhubhu yokuhamba ibona amandla ombane. Indawo yee-electrode ibalulekile; ngokuqhelekileyo zibekwe phezulu kunye nezantsi kwityhubhu yokuhamba ukuze kuqinisekiswe ukufundwa ngokuchanekileyo kungakhathaliseki ukuba ijika lokuhamba.
4. Ukwenziwa komqondiso
Isignali yombane efunyenweyo ithunyelwa kwi-transmitter, eqhuba ulwazi. Umthumeli uguqula i-voltage ibe ngumlinganiselo wokuhamba, ngokuqhelekileyo uboniswa kwiiyunithi ezifana neelitha ngomzuzu (L / min) okanye iigaloni ngomzuzu (GPM).
5. Isiphumo:
Ekugqibeleni, idatha yokuhamba ingabonakaliswa kwisikrini, irekhodwe ukuhlalutya kwexesha elizayo, okanye idluliselwe kwinkqubo yokulawula ukujonga ixesha langempela kunye nokulawula.
Izinto ezilungileyo ze-electromagnetic flowmeter
Izinto eziluncedo ze-electromagnetic flowmeters ikakhulu zibandakanya ukuchaneka okuphezulu komlinganiso, akukho lahleko yoxinzelelo, ubungakanani boluhlu olubanzi, ukuchasana nokugqwala okuqinileyo, uluhlu olubanzi lwesicelo, impendulo enovakalelo, ukufakwa lula, ukusetyenzwa komqondiso wedijithali, ukuchasana nokuphazamiseka, njl.
Ukusetyenziswa kwe-electromagnetic flowmeter
● Ukucocwa kwamanzi kunye namanzi amdaka: Ukubeka iliso kwindlela yokuhamba yokucoca ukuqinisekisa ukuthotyelwa kwemimiselo yokusingqongileyo.
● Ukusetyenzwa kweekhemikhali: Linganisa ukuhamba kolwelo oludlekayo okanye olubonakalayo kwimveliso yeekhemikhali.
● Ishishini lokutya neziselo: Qinisekisa umlinganiselo ochanekileyo wokuhamba kolwelo olufana nejusi, ubisi, nesosi, nto leyo ebalulekileyo ekulawuleni umgangatho.
● I-Pharmaceutical: Ukubeka iliso ukuhamba kwezithako ezisebenzayo kunye ne-solvents kwinkqubo yamayeza.
Sikwabonelelaii-electrodes ezisezantsi (amakhonkco okumisa)ukuze zisetyenziswe kwiimeko apho ii-electromagnetic flowmeters zifuna isikhokelo sangoku, ukupheliswa kokuphazamiseka, kunye nokuqinisekisa intembeko yelophu yomqondiso.
