Iingenelo ze-electromagnetic flowmeter

I-electromagnetic flowmeter sisixhobo sokulinganisa ukuhamba kwamanzi esisetyenziswa rhoqo, esineempawu ezilandelayo:
1. Ukuchaneka okuphezulu kokulinganisa: Ukuchaneka kokulinganisa kwe-electromagnetic flowmeter kudla ngokufikelela kwi-±0.5%, nto leyo enokulinganisa ngokuchanekileyo ukuhamba kolwelo, kwaye igcine ukuchaneka okuphezulu kwiindidi ezahlukeneyo zokuhamba.
Uluhlu olubanzi lokulinganisa: uluhlu lwayo lokulinganisa lungafikelela kwi-100:1 okanye lubanzi kunolo luqhelekileyo, lunokulungelelanisa neemfuno zokulinganisa ubungakanani bokuhamba kwamanzi obahlukeneyo, nokuba kukuhamba kwamanzi okuncinci okanye ukuhamba kwamanzi amakhulu, lunokulinganiswa ngokuthembekileyo.

2. Iimfuneko eziphantsi kwiimpawu zolwelo: inokulinganisa iintlobo ngeentlobo zolwelo oluqhubayo, kuquka ii-asidi, ii-alkali, izisombululo zetyuwa kunye ne-grout equlethe amasuntswana aqinileyo, phantse angachaphazeleki lutshintsho kubushushu bolwelo, uxinzelelo, uxinano, i-viscosity kunye nezinye iiparameter zomzimba.

3. Akukho lahleko yoxinzelelo: Ityhubhu yokulinganisa ye-electromagnetic flowmeter ayinazo izinto ezithintela ukuhamba kolwelo, kwaye ulwelo lunokudlula kakuhle, ngoko ke akukho lahleko yoxinzelelo ngexesha lenkqubo yokulinganisa, nto leyo ebaluleke kakhulu kwezinye iinkqubo ezineemfuno zoxinzelelo oluphezulu.

4. Isantya sokuphendula ngokukhawuleza: Ingasabela ngokukhawuleza kutshintsho lokuhamba, umlinganiselo kunye nemiqondiso yokuhamba ngexesha langempela, kwaye ingasetyenziselwa ukulinganisa nokuhamba okuguquguqukayo kunye nolawulo.

5. Ukuthembeka okuphezulu: akukho zinto zishukumayo, akukho lula ukuzinxiba okanye ukuzilimaza, zinokuthembeka okuphezulu nokuzinza, ubomi benkonzo ende, umthwalo omncinci wokugcinwa.

6. Ukulinganisa ngeendlela ezimbini: kunokulinganisa ukuhamba phambili nangasemva, kulungele imfuneko yokujonga ukuhamba ngeendlela ezimbini, njengokuba ulwelo olukwipayipi lunokubonakala kwimeko echaseneyo.

7. Izinto ezahlukeneyo ze-lining: Ngokweempawu ezahlukeneyo zolwelo kunye nendawo yokusetyenziswa, izinto ezahlukeneyo ze-lining zingakhethwa, ezifana ne-polytetrafluoroethylene, i-neoprene, njl.njl., ukuphucula ukumelana nokugqwala kunye nokumelana nokuguguleka kwemitha yokuhamba.

8. Imiqondiso yemveliso etyebileyo: idla ngokuba neendidi ezahlukeneyo zemiqondiso yemveliso, njengemiqondiso yangoku ye-4-20mA, imiqondiso yepulse, imiqondiso yedijithali, njl.njl., okulula ukuyidibanisa neenkqubo ezahlukeneyo zolawulo oluzenzekelayo ukuze kufezekiswe ukujonga kude kunye nokucutshungulwa kwedatha yethrafikhi.

9. Iimfuno ezingqongqo zokufakela: ukufakwa kufuna ubude obuthile becandelo lombhobho othe tye ngaphambi nasemva kokufakela, ngokubanzi ubukhulu bombhobho ongaphezulu buphindwe ka-5-10, ubukhulu bombhobho osezantsi buphindwe ka-3-5, ukuqinisekisa ukuba ukuhamba kolwelo kwityhubhu yokulinganisa kuzinzile, kunciphisa impembelelo ekuchanekeni kokulinganisa. Kwangaxeshanye, imitha yokuhamba kufuneka ifakwe kwindawo yokuthintela ukuphazamiseka okunamandla kwentsimi yemagnethi.

10. Iimfuneko zokuqhuba ulwelo: umzimba olinganisiweyo kufuneka ube nokuqhuba okuthile, iimfuno ngokubanzi zokuqhuba ulwelo zingaphezulu kwe-5μS/cm, ukuze ukuqhubela ulwelo oluphantsi kakhulu, njengamanzi acocekileyo, imfuneko yonyango olukhethekileyo okanye ezinye iintlobo zeemitha zokuhamba ukuze kulinganiswe.
