1. Ukulinganisa Okungaphazamisi Ngokulahlekelwa Okuncane Kokucindezela

• Akukho Zithiyo Endleleni Yokugeleza: Ngokungafani nama-flowmeter e-turbine, i-vortex, noma i-orifice plate, ama-flowmeter e-electromagnetic awanazo izingxenye ezihambayo, izinzwa eziphumayo, noma izingxenye ze-throttling epayipini. Ithubhu yokulinganisa ibushelelezi futhi iqondile, iqinisekisa ukuthi uketshezi lugeleza ngokwemvelo ngaphandle kokwehla okwengeziwe kwengcindezi.
• Ifanele Izinhlelo Eziphansi Zokucindezela: Lesi sici sizenza zilungele ukusetshenziswa lapho ukuzinza kwengcindezi kubalulekile khona, njengamanethiwekhi okuhambisa amanzi kamasipala, ukwelashwa kwendle, noma ukuthuthwa koketshezi okune-viscosity ephansi embonini yezemithi.

2. Ukunemba Okuphezulu Kokulinganisa kanye Nesilinganiso Sokujika Okubanzi

• Ukusebenza Okunembile: Ngaphansi kwezimo ezifanele, ukunemba kokulinganisa kungafinyelela ku-±0.2% wenani elilinganisiwe (kumamodeli ajwayelekile) noma ngisho no-±0.1% wezinguqulo ezinembe kakhulu, kanye nokuphindaphindeka okuhle kakhulu (≤±0.1%).
• Isilinganiso Esibanzi Sokuguquka: Ngokuvamile sisukela ku-100:1 kuya ku-500:1 (amanye amamodeli athuthukile afinyelela ku-1000:1), okuvumela ukulinganisa okuzinzile ebangeni elibanzi lokugeleza—kusukela emazingeni aphansi okugeleza (isb., 几滴 ngomzuzwana kumapayipi amancane) kuya emazingeni aphezulu okugeleza (isb., amapayipi amakhulu ezimboni).
• Umphumela Ozinzile: Akuthintwa izinguquko ekujiyileni koketshezi, ukujiyileka, izinga lokushisa, noma ingcindezi (ngaphakathi kobubanzi obulinganisiwe), okuqinisekisa ukunemba okuqhubekayo kwemidiya enezakhiwo zomzimba ezahlukahlukene (isb., amanzi ashisayo, amanzi apholile, noma ama-slurries aqinile).

3. Ukuzivumelanisa Okuqinile Nemidiya Eyinkimbinkimbi

• Ifanelekela Ama-Conductive Fluids: Uma nje ukuqhutshwa kukagesi koketshezi kudlula u-5 μS/cm (umkhawulo ohlangatshezwa kalula yiziningi zezimboni eziwuketshezi, amanzi angcolile, ama-slurry, ngisho nezinye iziphuzo ezisebenzisa i-conductivity ephansi njengejusi yezithelo), kungalinganiswa ngempumelelo. Okuhlukile kufaka phakathi uwoyela omsulwa, ama-alcohol, noma amagesi anokuqhutshwa okuphansi kakhulu.
• Iphatha Izinto Ezikhethekile: Isebenza kahle ngoketshezi olubolayo (isb., ama-acid, ama-alkali), ama-slurry abrasive (isb., i-coal slurry, i-ore pulp), uketshezi olune-viscosity ephezulu (isb., isiraphu, i-latex), kanye noketshezi oluqukethe izinhlayiya noma imicu eqinile (isb., i-paper pulp, indle).
• Ukuguquguquka Kokungavikeleki Kwesimo Soketshezi: Akuthinteki ukuxokozela, amabhamuza, noma ukuhlukaniswa koketshezi, okwenza kube okuthembekile ezinhlotsheni ezifana nokuthuthwa kodaka noma izinqubo zokuxuba amakhemikhali.

4. Ukufakwa Okulula Nezinketho Zokufaka Ezihlukahlukene

• Izidingo Zokufaka Eziguquguqukayo: Ingafakwa kumapayipi avundlile, aqondile, noma athambekele, anezidingo ezincane zobude bepayipi eliqondile (ngokuvamile ezidinga i-5×DN phezulu kanye ne-3×DN phansi kwepayipi eliqondile, elingaphansi kakhulu kwamapuleti e-orifice noma ama-flowmeter e-turbine).
• Ububanzi Obukhulu: Kutholakala ngobubanzi bepayipi kusukela ku-DN1.5mm (ama-flowmeter amancane) kuya ku-DN3000mm (amamitha amanzi anobubanzi obukhulu), afaneleka kokubili ukulinganisa ukugeleza kwesikali selabhorethri kanye nesezimboni.
• Izinto Zokwenza Ulwelwesi Oluhlukahlukene: Ulwelwesi lwangaphakathi lwethubhu lokulinganisa (oluthinta uketshezi) lungenziwa ngezifiso ngezinto ezifana ne-PTFE, irabha, noma i-ceramic ukuze imelane nokugqwala, ukuguguleka, noma amazinga okushisa aphezulu, okuzivumelanisa nezici ezahlukene zemidiya.

5. Ukuthembeka Okuphezulu Nokulungiswa Okuphansi

• Azikho Izingxenye Ezinyakazayo: Iqeda izinkinga ezifana nokuguguleka kwemishini, ukuminyana, noma ukwehluleka kokukhathala, iqinisekisa ukusebenza okuzinzile kwesikhathi eside kanye nokuphila kwenkonzo okuvamile kweminyaka eyi-10-15.
• Ukucutshungulwa Kwesignali Yedijithali: Ama-flowmeter esimanje e-electromagnetic afakwe ama-microprocessor athuthukile emisebenzi efana nokuhlunga isignali, isinxephezelo sokushisa, kanye nokuzihlola (isb., ukuthola ukungcola kwe-electrode noma amaphutha ekhebula), ukunciphisa ama-alamu angamanga.
• Izidingo Ezincane Zokulungisa: Ukulungiswa okuvamile kuhilela kakhulu ukuhlola ukuhlanzeka kwe-electrode (ikakhulukazi kuma-media athambekele ekukhuleni) nokuqinisekisa ubuqotho be-lining, ngaphandle kwesidingo sokulinganiswa njalo ngaphansi kwezimo zokusebenza ezijwayelekile.

6. Izinzuzo Zemvelo Nokuphepha

• Ukuhambisana Nezindinganiso Zokuhlanzeka: Ekusetshenzisweni kokudla, iziphuzo, kanye nemithi, ama-flowmeter kagesi angaklanywa ngama-flanges ahlanzekile, ama-linings angaphakathi abushelelezi (isb., i-PTFE yezinga lokudla), futhi awanawo amakhona aqinile, ahlangabezana nezidingo ze-FDA, 3-A, noma ze-EHEDG ukuze kugwenywe ukungcola.
• Ifanelekela Izindawo Eziyingozi: Amamodeli angaqhumi (i-ATEX, isitifiketi se-IECEx) ayatholakala ukuze asetshenziswe ezindaweni ezivuthayo noma eziqhumayo (isb., izitshalo zamakhemikhali eziphatha izinyibilikisi ezishintshashintshayo), okuqinisekisa ukuphepha kokusebenza.
• Ukusebenza Kahle Kwamandla: Njengoba kungekho ukulahleka kwengcindezi, uhlelo ludinga amandla amancane okupompa ukuze lugcine ukugeleza koketshezi, okufaka isandla ekongeni amandla ekusebenzeni kwesikhathi eside.

Imikhawulo Okufanele Uyicabangele

• Ukuncika Ekuqhubeni Amandla: Awukwazi ukulinganisa imidiya engaqhubeki njengowoyela, utshwala, noma amagesi.
• Ukuzwela Ezimweni Zephayiphi: Ukuphazamiseka kwe-electromagnetic yangaphandle (isb., okuvela kuma-motor noma izintambo ze-voltage ephezulu) noma ukusatshalaliswa koketshezi okungalingani kungathinta ukunemba kokulinganisa, kudinge ukumisa nokufakwa okufanele.
• Izindleko Zokuqala Eziphakeme: Uma kuqhathaniswa nama-flowmeter omshini, ama-flowmeter kagesi anotshalomali oluphezulu kusengaphambili, yize lokhu kuvame ukuncishiswa yizindleko zokulungisa eziphansi zesikhathi eside.
• Izithiyo Zobukhulu Zokuqhuba Okuphansi Kakhulu: Kwimidiya eqhuba okuphakathi kuka-1–5 μS/cm (isb., amanzi ahlanzekile), ukunemba kokulinganisa kungancipha, kudinge amamodeli akhethekile okuqhuba okuphansi.
