1. Ukulinganisa okungaphazamisiyo kunye nokulahlekelwa koxinzelelo oluncinci

• Akukho Zithintelo Kwindlela Yokuhamba: Ngokungafaniyo nee-turbine, i-vortex, okanye ii-orifice plate flowmeters, ii-electromagnetic flowmeters azinazo iindawo ezihambayo, ii-sensors eziphumayo, okanye izinto ezithintela ukushukuma kwipayipi. Ityhubhu yokulinganisa igudile kwaye ithe tye, iqinisekisa ukuba ulwelo luhamba ngokwendalo ngaphandle kokwehla koxinzelelo olongezelelweyo.
• Ifanelekile kwiinkqubo zoxinzelelo oluphantsi: Olu phawu luzenza zilungele ukusetyenziswa apho uzinzo loxinzelelo lubaluleke kakhulu, njengothungelwano lwamanzi lukamasipala, unyango lwelindle, okanye ukuthuthwa kolwelo olungena-viscosity ephantsi kwishishini lamayeza.

2. Ukuchaneka koMlinganiselo oPhezulu kunye nomlinganiselo wokujika okubanzi

• Ukusebenza ngokuchanekileyo: Phantsi kweemeko ezifanelekileyo, ukuchaneka kokulinganisa kunokufikelela kwi-±0.2% yexabiso elilinganisiweyo (kwiimodeli ezisemgangathweni) okanye nakwi-±0.1% kwiinguqulelo ezichanekileyo, kunye nokuphindaphinda okuhle kakhulu (≤±0.1%).
• Umlinganiselo obanzi wokujika: Ngokwesiqhelo ususela kwi-100:1 ukuya kwi-500:1 (ezinye iimodeli eziphambili ukuya kuthi ga kwi-1000:1), okuvumela ukulinganiswa okuzinzileyo kuluhlu olubanzi lokuhamba kwamanzi—ukusuka kumazinga aphantsi okuhamba kwamanzi (umz., 几滴 ngomzuzwana kwiipayipi ezinobubanzi obuncinci) ukuya kumazinga aphezulu okuhamba kwamanzi (umz., iipayipi zoshishino ezinobubanzi obukhulu).
• Isiphumo Esizinzileyo: Asichaphazeleki lutshintsho kubuninzi bolwelo, ukuxinana, ubushushu, okanye uxinzelelo (ngaphakathi koluhlu olulinganisiweyo), ukuqinisekisa ukuchaneka okulinganayo kwimidiya eneempawu ezahlukeneyo zomzimba (umz., amanzi ashushu, amanzi okupholisa, okanye amaqhekeza aqinileyo).

3. Ukulungelelaniswa Okuqinileyo Neendaba Ezintsonkothileyo

• Ifanelekile kwii-Conductive Fluids: Logama nje i-conductivity yombane ye-fluid idlula i-5 μS/cm (umlinganiselo ofikeleleka lula luninzi lwe-liquids kwimizi-mveliso, amanzi amdaka, i-slurry, kunye nezinye ii-liquids ezine-conductivity ephantsi njengejusi zeziqhamo), ingalinganiswa ngempumelelo. Izinto ezingabandakanywanga ziquka iioyile ezicocekileyo, ii-alcohols, okanye iigesi ezine-conductivity ephantsi kakhulu.
• Iphatha iMidiya ekhethekileyo: Isebenza kakuhle ngezinto ezirhabaxa (umz., iiasidi, iialkali), izinto ezirhabaxa (umz., izinto ezirhabaxa zamalahle, izinto ezimdaka), izinto ezithambileyo ezinobuthi obuphezulu (umz., isiraphu, ilatex), kunye nezinto eziqulathe amasuntswana aqinileyo okanye imicu (umz., izinto ezirhabaxa zephepha, izinto ezimdaka).
• Utshintsho kwiMeko yoLwakhiwo: Ayichaphazeleki kukuphazamiseka, amaqamza, okanye ukwahlulwahlulwa kolwakhiwo, nto leyo eyenza ukuba luthembeke kwiinkqubo ezifana nokuthutha udaka okanye iinkqubo zokuxuba iikhemikhali.

4. Ufakelo Olulula kunye neenketho zokuFaka eziSebenza ngeendlela ezahlukeneyo

• Iimfuneko zoFakelo oluGuquguqukayo: Ingafakelwa kwiipayipi ezithe tye, ezithe nkqo, okanye ezithambekileyo, kwaye ubude bepayipi buncinci (ngokuvamile ifuna i-5 × DN phezulu kunye ne-3 × DN esezantsi kombhobho othe tye, ingaphantsi kakhulu kuneepleyiti ze-orifice okanye ii-flowmeter ze-turbine).
• Uluhlu olubanzi lobukhulu: Ifumaneka kwiidayamitha zepayipi ukusuka kwi-DN1.5mm (ii-micro flowmeters) ukuya kwi-DN3000mm (iimitha zamanzi ezinobukhulu obukhulu), zifanelekile zombini ukulinganisa ukuhamba kwamanzi ngokwesikali selabhoratri kunye nesemizi-mveliso.
• Izinto ezahlukeneyo zokuLungisa: Ulwelo lwangaphakathi lwetyhubhu yokulinganisa (oludibana nolwelo) lunokwenziwa ngokwezifiso ngezinto ezifana ne-PTFE, irabha, okanye iseramikhi ukuze kumelwane nokugqwala, ukuguguleka, okanye amaqondo obushushu aphezulu, ukuze kuhambelane neempawu ezahlukeneyo zemidiya.

5. Ukuthembeka Okuphezulu kunye nokugcinwa okuphantsi

• Akukho Zinto Zishukumayo: Iphelisa iingxaki ezifana nokuguguleka koomatshini, ukuxinana, okanye ukungasebenzi kakuhle kokudinwa, iqinisekisa ukusebenza okuzinzileyo ixesha elide kunye nobomi benkonzo eqhelekileyo yeminyaka eli-10 ukuya kweli-15.
• Ukucubungula iSignali yeDijithali: Ii-flowmeters ze-electromagnetic zanamhlanje zixhotyiswe ngee-microprocessors eziphambili zemisebenzi efana nokucoca isignali, ukuhlawula ubushushu, kunye nokuzixilonga (umz., ukubona ukungcola kwe-electrode okanye iimpazamo zekhebula), ukunciphisa ii-alamu zobuxoki.
• Iimfuno Ezincinci Zokugcinwa: Ukugcinwa rhoqo kubandakanya ukujonga ukucoceka kwe-electrode (ingakumbi kwiindawo ezikwaziyo ukukala) kunye nokuqinisekisa ukuthembeka kwe-lining, ngaphandle kwemfuneko yokulungiswa rhoqo phantsi kweemeko zokusebenza eziqhelekileyo.

6. Iingenelo zeNdalo kunye noKhuseleko

• Ukuthobela iMigangatho yoKucoceka: Kwizicelo zokutya, iziselo, kunye namayeza, ii-electromagnetic flowmeters zinokuyilwa ngee-sanitary flanges, ii-linings zangaphakathi ezigudileyo (umz., i-PTFE yodidi lokutya), kwaye azikho iikona ezifileyo, ezihlangabezana neemfuno ze-FDA, 3-A, okanye ze-EHEDG ukuthintela ungcoliseko.
• Ifanelekile kwiindawo ezinobungozi: Iimodeli ezikwaziyo ukumelana nokuqhuma (i-ATEX, i-IECEx eqinisekisiweyo) ziyafumaneka ukuze zisetyenziswe kwiindawo ezinokutsha okanye eziqhumayo (umz., izityalo zeekhemikhali eziphatha izinyibilikisi eziguquguqukayo), ukuqinisekisa ukhuseleko lokusebenza.
• Ukonga Amandla: Ekubeni kungekho lahleko yoxinzelelo, inkqubo ifuna amandla amancinci okumpompa ukugcina ukuhamba kolwelo, okufaka isandla ekongeni amandla ekusebenzeni ixesha elide.

Imida Ekufuneka Iqwalaselwe

• Ukuxhomekeka kwi-Conductivity: Ayikwazi ukulinganisa izixhobo ezingezizo eziqhuba umbane ezifana neeoyile, ii-alcohols, okanye iigesi.
• Uvakalelo kwiiMeko zePipeline: Ukuphazamiseka kwe-electromagnetic yangaphandle (umz., okuvela kwiimoto okanye kwiintambo ze-voltage ephezulu) okanye ukusasazwa kolwelo olungalinganiyo kunokuchaphazela ukuchaneka kokulinganisa, okufuna ukumisa umhlaba ngokufanelekileyo kunye nokufakelwa.
• Ixabiso Lokuqala Eliphezulu: Xa kuthelekiswa nee-flowmeters zoomatshini, ii-flowmeters ze-electromagnetic zinotyalo-mali oluphezulu oluvela kwangaphambili, nangona oku kudla ngokulungiswa ziindleko eziphantsi zokugcinwa kwexesha elide.
• Imiqobo yobukhulu boMbane oPhantsi kakhulu: Kwimidiya enombane ophakathi kwe-1–5 μS/cm (umz., amanzi acocekileyo), ukuchaneka komlinganiselo kunokwehla, kufuna iimodeli ezikhethekileyo zombane ophantsi.
