1. Izinzuzo Zokulinganisa Okuyinhloko

• Ukunemba okuphezulu kokulinganisa: Ukunemba okuvamile kusuka ku-±1.0% kuya ku-±1.5% FS (±0.5% FS yamamodeli anokunemba okuphezulu), ngephutha lokuphindaphinda elingu-≤0.3%, elihlangabezana nezidingo zokuxazululwa kokuhweba kanye nokulawulwa kwenqubo.
• Isilinganiso sokujika okubanzi: Isilinganiso esijwayelekile singu-1:10 kuya ku-1:20, singandiswa sibe ngu-1:30 kumamodeli athile, sihlanganisa izilinganiso zebanga lokugeleza okubanzi (isb., ukugeleza komusi kusuka emthwalweni ophansi kuya kogcwele).
• Ukuzivumelanisa nezimo okubanzi okuphakathi nendawo: Iyakwazi ukulinganisa izinhlobo ezintathu zemidiya—amagesi (igesi yemvelo, i-nitrogen, umoya ocindezelwe, njll.), uketshezi (amanzi, uwoyela, izinyibilikisi zamakhemikhali, njll.), kanye nomusi (umusi ogcwele/oshisiwe kakhulu)—ngaphandle kokufaka izingxenye eziyinhloko zemidiya ehlukene.

2. Izici Zesakhiwo Nokufakwa

• Azikho izingxenye ezihambayo: Iyunithi yokulinganisa eyinhloko ayinazo izingxenye ezijikelezayo noma ezigqokwayo ngomshini, okuholela ekuhlulekeni okuphansi kanye nokuphila isikhathi eside (iminyaka emi-5 ~ 10 ngaphansi kwezimo ezijwayelekile) ngezindleko zokulungisa ezincane.
• Ukulahlekelwa yingcindezi ephansi: Ukumelana nokugeleza koketshezi kuyi-1/3 ~ 1/5 kuphela yama-orifice flowmeter, okunciphisa ukulahleka kwamandla epayipi, okulungele kakhulu ukusetshenziswa kobubanzi obukhulu kanye nokucindezela okuphansi.
• Ukufakwa okulula: Isekela ukufakwa okuvundlile, okuqondile, nokuthambekele, ngezidingo zamapayipi aqondile akhululekile (ngokuvamile i-10D phezulu komfula / i-5D phansi komfula; amanye amamodeli anesakhiwo sokulungisa angafinyezwa abe yi-5D phezulu komfula / i-3D phansi komfula, lapho i-D = ububanzi bepayipi), okuqinisekisa ukuzivumelanisa nezimo okuqinile endaweni.
• Isakhiwo esincane: Usayizi omncane kanye nesisindo esilula, okulungele izindawo ezincishisiwe (isb., amakamelo emishini amancane, amapayipi aphezulu).

3. Ukuzivumelanisa Nezimo Zokusebenza

• Ukumelana nokushisa okuphezulu kanye nengcindezi: Amamodeli ajwayelekile amelana no--40℃ ~ 350℃ kanye no-≤4.0MPa; amamodeli enziwe ngokwezifiso anganwebeka ku-500℃ kanye no-16MPa, afanelekela ukulinganisa umusi kanye noketshezi lwenqubo yokushisa okuphezulu.
• Amandla aqinile okulwa nokuphazamiseka: Ifakwe izinzwa ze-piezoelectric noma ze-capacitive ezihlanganiswe nobuchwepheshe bokuhlunga bedijithali, imelana ngempumelelo nokudlidliza kwamapayipi, ukuphazamiseka kwe-electromagnetic, kanye nokushaya okuphakathi (amanye amamodeli abonisa ukwakheka kokulwa nokudlidliza, kanye nephutha elibangelwa ukudlidliza elingu-≤±0.1% FS).
• Izinketho zokumelana nokugqwala/ukuguguleka: Ngezinto ezikhethekile (izixazululo ze-acid-base, amagesi anothuli), izinto ezifana nensimbi engagqwali, i-PTFE lining, kanye ne-Hastelloy ziyatholakala ukuze kwandiswe izimo zokusetshenziswa.

4. Izinzuzo Zokusebenza Nokulungisa

• Akukho ukulinganiswa kwendawo okudingekayo: Ngokusekelwe ezimisweni zokulinganisa ngokomzimba, ukulinganiswa kwasefektri ngamadivayisi ajwayelekile kuqeda isidingo sokulungiswa kabusha endaweni (uma nje amapharamitha aphakathi ehambisana nezimo zokulinganisa).
• Izimpawu zokukhipha ezicebile: Isekela isignali ye-analog engu-4 ~ 20mA, isignali ye-pulse, kanye nokukhishwa kwesignali yedijithali ye-RS485 (Modbus protocol), exhuma ngqo ku-PLC, izinhlelo ze-DCS, noma imishini yokuthola idatha yokulawula okuzenzakalelayo.
• Izindleko zokusebenza eziphansi: Akukho okudliwayo noma ukuhlukaniswa okuvamile okudingekayo; kudingeka ukuhlolwa njalo kokuqina kwe-flange kanye nezintambo zenzwa, okunciphisa umthwalo wokulungisa.

5. Imikhawulo (yereferensi yokukhetha)

• Ayizweli kwimidiya enejubane eliphansi, ene-viscosity ephezulu: Idinga inombolo kaReynolds Re ≥20,000 (amagesi) noma ≥5,000 (uketshezi); ngaphandle kwalokho, iphutha lokulinganisa liyakhula. Akufanele uwoyela osindayo, uketshezi olune-viscous, njll.
• Imfuneko yokuhlanzeka okumaphakathi: Izinhlayiya ezinkulu eziqinile (usayizi wezinhlayiya ＞5mm) zingavimba izinzwa noma zilimaze izinto zokuthola, okudinga izihlungi ukuze zisetshenziswe.
• Ayisebenzi eziwuketshezini ezingezona eze-Newtonian: Ama-slurries noma uketshezi olunezinhlayiya eziqinile ezilengayo kakhulu luzothinta ukuqina kwe-vortex, okuholela ekwehlulekeni kokulinganisa.
