Ixesha lokulinganisa ii-flowmeters ze-clamp-on ultrasonic alikho semgangathweni kwaye kufuneka limiselwe ngokusekelwe kudibaniso lweemeko zesicelo, imigaqo yoshishino, iimfuno zokuchaneka kokulinganisa, kunye nokuzinza kwezixhobo. Ngokwesiqhelo liwela kwiindidi ezimbini: "iixesha ezicetyiswayo ngokubanzi" kunye "neemeko ezikhethekileyo zokubangela."
I. Amaxesha Okulinganisa Acetyiswayo Jikelele (Ngokusekelwe Kuzinzo Lokusebenza)
Ngokuxhomekeke ekubeni imeko yesicelo inzima kangakanani, amaxesha okulinganisa ngokubanzi ahlala ehlelwa ngolu hlobo lulandelayo:
| Imeko yesicelo | Ikhefu lokulinganisa elicetyiswayo | Isizathu Esiphambili |
|---|---|---|
| Iinkqubo ezibalulekileyo zoshishino (umz., ukondla ngempendulo yamachiza, ukulinganisa amandla ukuze kuhlalwe) | Unyaka o-1–2 | Ibandakanya ukhuseleko lwemveliso kunye nokubalwa kweendleko, ifuna ukuchaneka okuphezulu kokulinganisa (ngesiqhelo ±1%–±2%), nto leyo edinga ukuqinisekiswa rhoqo. |
| Ukubeka iliso kumasipala ngezinto ezisetyenziswayo (umz., izibalo zokuhanjiswa kwamanzi/ukuhamba kwamanzi amdaka, amanzi ajikeleza i-HVAC) | Iminyaka emi-2–3 | Iimfuneko zokuchaneka okuphakathi (±2%–±3%) kunye neemeko zokusebenza ezizinzileyo, kodwa kufuneka ukujonga ukuthotyelwa kwedatha rhoqo. |
| Ukubeka iliso kwinkqubo ngokubanzi (umz., amanzi okupholisa izixhobo, ukudluliselwa kwezinto ezingabalulekanga) | Iminyaka emi-3–5 | Igxila "ekujongeni imeko" ngeemfuno ezichanekileyo eziphantsi (±3%–±5%), ivumela amathuba amade. |
II. "Iimeko Ezikhethekileyo Zokubangela Ingxaki" Ezifuna Ukulungiswa Kwangoko
Ukulinganisa okanye ukuqinisekisa kufuneka kwenziwe ngoko nangoko ukuba kukho nayiphi na kwezi zilandelayo, nokuba ixesha eliqhelekileyo alikafikelelwa:
- Utshintsho olungaqhelekanga kwidatha yokulinganisa
Xa ixabiso elibonisiweyo le-flowmeter lingafani kakhulu neemeko zokusebenza zangempela (umz., i-frequency yepompo, uxinzelelo lwepayipi, iiparameter zenkqubo ezisezantsi/ezisezantsi) — umzekelo, ipompo enomlinganiselo wokuhamba we-100m³/h kodwa imitha ibonisa rhoqo i-120m³/h okanye i-80m³/h ngaphandle kwesizathu esivakalayo — ukungahambi kakuhle kwe-sensor okanye ukushukuma kweparameter kunokuba negalelo, kufuna ukulinganiswa ukuze kuchongwe iingxaki. - Ukuchatshazelwa kwezixhobo kwiimeko ezimandundu okanye ukuphazamiseka komzimba
- Ukungcangcazela, impembelelo, okanye ukufuduka kwepayipi okunciphisa ukunamathela kwesenzi esibambekayo.
- Utshintsho olukhulu ngequbuliso kubushushu okanye kwi-viscosity yesixhobo esilinganisiweyo (umz., ukusuka kwi-atmospheric ukuya kwi-100°C) okanye ukwanda kokungcola/amaqamza.
- Ukuguquguquka kwevolthi, ukubetha kombane, okanye ukufuma okuphezulu okunokuchaphazela imijikelezo yangaphakathi okanye ukuchaneka kwemodyuli yokulinganisa.
- Emva kokususwa/ukufakelwa kwakhona kwesensor
Izinzwa ze-Clamp-on zixhomekeke ekudibaneni okuqinileyo nomphandle wombhobho (ezikhuselwe nge-arhente/ii-clamps zokudibanisa). Ukuzisusa nokuzifaka kwakhona (umz., ukugcinwa okanye ukuhlolwa kombhobho) kunokutshintsha indawo, i-engile, okanye uxinzelelo loqhagamshelwano, okufuna uhlengahlengiso ukuqinisekisa ukuchaneka. - Imithetho yoshishino okanye iimfuno zophicotho-zincwadi
Amashishini athile (umz., ioyile, igesi, ukutya, amayeza) aphantsi kwemigangatho yesizwe enyanzelekileyo okanye uphicotho-zincwadi lomntu wesithathu, olufuna ukulinganiswa ngamaxesha athile (umz., ngaphambi kophicotho-zincwadi zokhuseleko lonyaka) ukuqinisekisa ukuthotyelwa kwemigaqo (umz., uMthetho weMetrology waseTshayina wezixhobo zokusombulula urhwebo). - Izixhobo ezigugayo okanye ezilungiswa emva kokuguga
Ii-Flowmeters ezisebenza iminyaka engaphezu kwemi-5, okanye ezo zinezixhobo eziphambili ezitshintshiweyo (umz., ibhodi ephambili, ii-sensors), zisenokuziva zishukuma kwaye zifune ukulinganiswa ukuze kubuyiselwe ukuchaneka.
III. Iindlela zoLungiso kunye nokuqwalaselwa
- Iindlela eziqhelekileyo zokulinganisa
- Ukulinganisa okuthelekisayo kwindawo: Ukusebenzisa i-flowmeter esemgangathweni ephathekayo (umz., i-ultrasonic okanye i-electromagnetic flowmeter ephathekayo) ukulinganisa umbhobho ofanayo, ukuthelekisa ukuphambuka (okulula kwaye okungabizi kakhulu kwiimeko ezininzi zoshishino).
- Ukulinganiswa kwelebhu: Ukuthumela i-flowmeter kwiziko le-metrology elivunyiweyo yi-CNAS ukuze lilinganiswe ngokupheleleyo kwizixhobo zokuhamba ezisemgangathweni (ukuchaneka okuphezulu, okufanelekileyo kwisivumelwano sorhwebo okanye kwiinkqubo ezibalulekileyo).
- Iindlela zemihla ngemihla "zokuqinisekisa ukukhanya"
Xa kungekho kulungiswa ngokusesikweni, kunokwenziwa uvavanyo olulula olusebenzisa "indlela ye-pipeline static volume": Vala iivalvu ezisezantsi/phezulu, urekhode ububanzi bombhobho, ubude, kunye nexesha lokuzalisa umbhobho, uze uthelekise ukuhamba kwethiyori nokufundwa kwemitha (ukuze ufumane ireferensi echanekileyo kuphela, kungekhona indawo yokulungiswa ngokusesikweni).
Isishwankathelo
Ixesha lokulinganisa ii-flowmeters ze-clamp-on ultrasonic kufuneka "lisekelwe kwiimfuno": iminyaka eli-1-2 kwiimeko ezibalulekileyo, iminyaka emi-2-3 yokusetyenziswa ngokubanzi, kunye neminyaka emi-3-5 kwizicelo ezingezizo ezibalulekileyo. Kufuneka ihlengahlengiswe ngokuguquguquka ngokusekelwe kwiimeko ezikhethekileyo ezifana nokungahambi kakuhle kwedatha, ukuphazamiseka kwezixhobo, okanye iimfuno zomthetho. Ukulinganisa rhoqo kuqinisekisa ukuchaneka kokulinganisa, ukubona iimpazamo ezinokubakho kwangethuba, kwaye kwandisa ubomi bezixhobo.
