Iimitha zokuhamba kobunzima beCoriolis (iiCMFM) zidibanisa ubuchwepheshe obuphambili bokuziva kunye noyilo lwesakhiwo ukuze zinike umlinganiselo wokuhamba othembekileyo nosebenzayo. Nazi iimpawu zazo eziphambili, ezilungiselelwe iinkcukacha zobugcisa, amaxwebhu okuthumela ngaphandle, kunye neengcebiso zobugcisa zabathengi:
Ulwakhiwo Lokuziva Olusekelwe Ekungcangcazeleni Ixhotyiswe ngetyhubhu enye okanye ezingaphezulu zokulinganisa ezingcangcazelayo (uyilo oluqhelekileyo: olumile okwe-U, oluthe tye, olugobileyo kabini, okanye olugobileyo olunye), oluqhutywa yi-actuator ye-piezoelectric okanye ye-electromagnetic kwi-frequency yendalo yetyhubhu. Ukungcangcazela kuzinzile kwaye akuchaphazeleki lula kukuphazamiseka koomatshini bangaphandle, okuqinisekisa ukubonwa rhoqo komahluko wesigaba esibangelwa ngamandla eCoriolis.
I-Direct Mass Flow SensingImpawu ephambili eyahlula kwiimitha zokuhamba kwevolumu: ilinganisa ngokuthe ngqo ukuhamba kwesisindo ngokufumanisa umahluko wesigaba phakathi kwesiphelo sokungena kunye nesiphelo sokuphuma kwetyhubhu engcangcazelayo. Oku kususa imfuneko yokubala uxinano, ubushushu, okanye uxinzelelo, kuthintelwe iimpazamo eziqokelelweyo ezivela ekuguqulweni okungathanga ngqo.
Ubungakanani bokuLinganisa iiParamitha ezininzi
Isixhobo esinye singalinganisa isantya sokuhamba kobunzima ngaxeshanye, uxinano lolwelo, kunye nobushushu ngaphandle kwee-sensors ezongezelelweyo. Ukulinganisa uxinano, kusebenzisa ulwalamano phakathi kwemvamisa yendalo yetyhubhu engcangcazelayo kunye noxinano lolwelo ngaphakathi; ubushushu bufunyanwa zii-sensors zobushushu ezakhelwe ngaphakathi eludongeni lwetyhubhu. Ezinye iimodeli eziphezulu zinokufumana isantya sokuhamba kwevolumu kunye noxinzelelo (kwimixube ye-binary).
Uyilo lweNdlela yokuHamba eNgenakuphazamisa Akukho zixhobo zishukumayo, imiqobo, okanye izinto ezithintelayo kwindlela yokuhamba kolwelo. Olu yilo luthintela ukulahleka koxinzelelo, luthintela ukuvaleka okanye ukuguguleka (kubalulekile kwi-slurry okanye kwi-viscous media), kwaye luqinisekisa ukudlula kolwelo okungathintelwanga, okwenza ukuba lufaneleke kwi-media ecocekileyo nengcolileyo.
Ukuphazamiseka Kokungazinzi Komzimba
Ayichaphazeleki kukuphazamiseka kweprofayili yokuhamba kwamanzi okubangelwa zizinto zepayipi ezisezantsi/phezulu (umz., ii-bends, ii-valve, ii-pumps). Ngokungafaniyo ne-vortex okanye ii-electromagnetic flow meter, ayifuni payipi ende ethe tye ukuze ifakwe, nto leyo evumela ukufakwa okuguquguqukayo kwiindawo ezincinci.
Ukuchaneka Okuphezulu kunye nozinzo
Iqhayisa ngokuchaneka okugqwesileyo (ngesiqhelo i-±0.1% ukuya kwi-±0.5% yokufunda) kwaye iyaphindaphindeka (±0.02% ukuya kwi-±0.1% yokufunda), ithobela imigangatho yamazwe ngamazwe efana ne-ISO 9104 kunye ne-ASTM D5125. Ukusebenza kokulinganisa kuhlala kuzinzile naphantsi kweemeko zokusebenza ezinzima (ubushushu obuphezulu, uxinzelelo oluphezulu, ukuxinana okuphezulu).
Ukuhambelana kweMidiya ebanzi kunye neSicelo
Ifanelekile ukulinganisa ulwelo (kuquka ulwelo olune-viscosity ephezulu njenge-oyile ekrwada kunye nezincamathelisi), iigesi, ukuhamba kwamanqanaba amaninzi (umz., ulwelo olunamaqamza afakwe ngaphakathi), kunye nezilayi (umz., izilayi zeminerali, iipaste zokutya). Isebenza kumashishini afana neoyile negesi, iikhemikhali, ukutya neziselo, amayeza, kunye nonyango lwamanzi amdaka.
Ukucubungula iSignali yeDijithali Kwamkela ii-transmitters zedijithali eziphambili ezine-adaptive filtering kunye ne-signal processing algorithms ezakhelwe ngaphakathi. Ezi algorithms zithintela ukuphazamiseka kokungcangcazela kwangaphandle, zonyusa umlinganiselo wesignali-kwingxolo, kwaye zivumela ukuphuma kwedatha ngexesha langempela (umz., 4–20 mA, HART, Modbus, Profibus) ukuze kudityaniswe kakuhle neenkqubo zolawulo lwemizi-mveliso.
