I-flowmeter ye-electromagnetic yohlobo oluhlukanisiweyo sisixhobo sokulinganisa ukuhamba okuchanekileyo kakhulu esiyilwe ngesakhiwo esahlukileyo se-sensor kunye ne-converter. Ifumana umgaqo wokulinganisa oyintloko wokungeniswa kwe-electromagnetic ngelixa isombulula imida yokufakela kunye nokusetyenziswa kweemodeli ezidibeneyo, okwenza ukuba isetyenziswe kakhulu kwiimeko ezinzima zoshishino.

1. Ulwakhiwo oluPhambili kunye noMgaqo wokuSebenza

• Izinto ezimbini ezibalulekileyo: I-sensor (efakwe kwindawo) inetyhubhu yokulinganisa, ii-electrode, i-excitation coil, kunye ne-lining. I-converter (efakwe kude) inoxanduva lokucubungula isignali, ukubonisa idatha, kunye nokuphuma kwayo.
• Indlela yokusebenza: Xa i-conductive medium idlula kwi-magnetic field ye-sensor, kuveliswa amandla e-electromotive aqhutywa ngokulingana nesantya sokuhamba. I-sensor iqokelela esi siginali ize isithumele kwi-converter ngentambo ekhethekileyo. Emva kokukhulisa, ukucoca, kunye nokubala, i-converter ikhupha imiqondiso eqhelekileyo (umz., 4-20mA, HART) okanye ibonise idatha yokuhamba ngokuthe ngqo.
• Imfuneko yoqhagamshelo: I-sensor kunye ne-converter ziqhagamshelwe ngentambo yesiginali ekhethekileyo, enomgama oqhelekileyo we-10-100 yeemitha (iyahluka ngokwemveliso kunye nemodeli).

2. Iingenelo eziphambili

• Ufakelo oluguquguqukayo: Uyilo olwahlulweyo luvumela ukuba i-converter ifakwe kwindawo elula, eyomileyo, nengaphazamisiyo, nokuba i-sensor ifakwe kwiindawo ezimxinwa, ezinzima, okanye ezinzima ukufikelela kuzo.
• Ukulungelelana okuqinileyo nokusingqongileyo: Isensor yenzelwe amanqanaba aphezulu okhuseleko (ngesiqhelo i-IP65/IP68) ukumelana nobushushu obuphezulu, ukufuma, ukungcangcazela, uthuli, kunye neegesi ezirhabaxa. Isiguquli siphepha ukuvezwa ngqo kwiimeko ezinzima, siqinisekisa ukusebenza okuzinzileyo.
• Ukusebenza nokugcinwa okulula: Isiguquli singafakwa kwigumbi lolawulo eliphakathi okanye kwinqanaba lamehlo, nto leyo eyenza kube lula ukusetwa kweparameter, ukufundwa kwedatha, kunye nokugcinwa rhoqo ngaphandle kokufikelela kwisenzi esikwindawo.

3. Iimeko eziqhelekileyo zokusetyenziswa

• Iindawo ezinobungozi kwindawo: Ezifana nezityalo zeekhemikhali, iindawo zokucoca ioyile, okanye izityalo zokucoca amanzi amdaka ezinobushushu obuphezulu, ukufuma okuphezulu, umhlwa onamandla, okanye uthuli olunzima.
• Ukufakelwa okunqongopheleyo: Kwimibhobho engaphantsi komhlaba, efakwe kwiindawo eziphakamileyo, okanye kwiindawo ezixineneyo zezixhobo apho kunzima ukufaka okanye ukusebenzisa iimitha ezidityanisiweyo.
• Iimfuno zokubeka esweni kude: Iiprojekthi ezifuna ukuqokelelwa kwedatha ebanzi, njengokuthuthwa kwemibhobho emide, imibhobho yangaphandle yemizi-mveliso, okanye imigca yemveliso emikhulu.

4. Amanqaku oKhetho oluPhambili kunye noFakelo

• Ukuhambelana kweentambo: Sebenzisa intambo yesiginali enikezelwe ngumenzi ukuthintela ukuncitshiswa kwesignali okanye ukuphazamiseka kwe-electromagnetic.
• Ukufakelwa kwesensor: Landela iimfuno ezifanayo neemodeli ezidityanisiweyo—qinisekisa ukuhamba kombhobho opheleleyo, iindawo ezaneleyo zemibhobho ethe tye (ngaphambili 10D/ngasemva 5D), ukugalelwa komhlaba ngokufanelekileyo (ukuxhathisa komhlaba <10Ω), kwaye uphephe ukufaka kufutshane neempompo, iivalvu, okanye iingqiniba.
• Indawo yokuguqula: Faka kwindawo eyomileyo, enomoya ococekileyo enobushushu obuphakathi kwe -10℃ ~ 60℃, kude nee-frequency converters, iintambo ze-high-voltage, okanye ezinye izixhobo zokuphazamisana ne-electromagnetic ezinamandla.
