Intshayelelo ye-Magnetic flowmeter

I-Electromagnetic flowmeter luhlobo lwemitha yokungenisa eyenziwe ngokomthetho kaFaraday we-electromagnetic induction ukulinganisa ukuhamba komthamo we-conductive medium kwityhubhu.Kwiminyaka yoo-1970 kunye no-1980, ukuhamba kwe-electromagnetic kwenze ukuphumelela okukhulu kwitekhnoloji, kuyenza ibe luhlobo olusetyenziswa ngokubanzi lwe-flowmeter, kwaye ipesenti yokusetyenziswa kwayo kwimitha yokuhamba iyenyuka.

Isishwankathelo seSicelo:

I-Electromagnetic flowmeter isetyenziswa ngokubanzi kwintsimi yeemitha ezinkulu ze-diameter zisetyenziswa ngakumbi kunikezelo lwamanzi kunye nobunjineli bokuhambisa amanzi;Ubungakanani obuncinci kunye nobukhulu obuphakathi buhlala busetyenziswa kwiimfuno eziphezulu okanye kunzima ukulinganisa izihlandlo, ezifana nentsimbi kunye noshishino lwentsimbi luqhuma isithando somlilo sokupholisa ulawulo lwamanzi, iphepha lomlinganiselo wephepha lokulinganisa iphepha kunye nolwelo olumnyama, ishishini lemichiza elomeleleyo lolwelo olunomhlwa, i-pulp ye-nonferrous metallurgy industry ;I-caliber encinci, i-caliber encinci isoloko isetyenziswa kwishishini lamachiza, ishishini lokutya, i-biochemistry kunye nezinye iindawo ezineemfuno zempilo.

Izinto eziluncedo:

1. Umjelo wokulinganisa ngumbhobho othe ngqo, ongayi kuvala, kwaye ufanelekile ukulinganisa ulwelo oluqinileyo olunezigaba ezibini ezinamasuntswana aqinileyo, afana ne-pulp, udaka, i-sewage, njl.

2. Ayivelisi ilahleko yoxinzelelo olubangelwa kukubona ukuhamba, kwaye inesiphumo esihle sokugcina amandla;

3. Umlinganiselo wokuhamba komthamo olinganisiweyo ngokwenene awuchaphazeli kakhulu utshintsho kwi-fluid density, viscosity, ubushushu, uxinzelelo kunye ne-conductivity;

4. uluhlu olukhulu lokuhamba, uluhlu olubanzi lwecaliber;

5. Kunokusetyenziswa ulwelo oludlekayo.

Izinto ezingeloncedo:

1. Ayikwazi ukulinganisa i-conductivity ephantsi kakhulu yolwelo, njengemveliso yepetroleum, amanzi acocekileyo, njl.;

2. ayikwazi ukulinganisa iigesi, umphunga kunye nolwelo ngamaqamza amakhulu;

3. ayinakusetyenziswa kumaqondo obushushu aphezulu.
