Ungalinganisa kanjani imitha yokugeleza?

Ukulinganisa imitha yokugelezakubalulekile ekuqinisekiseni ukunemba kokulinganisa phakathi noma ngaphambi kwezilungiselelo zezimboni. Akunandaba uketshezi noma amagesi, ukulinganisa kungesinye isiqinisekiso sokufundwa okunembile, okungaphansi kwezinga elamukelekayo. Iphinde yehlise ubungozi bamaphutha futhi ithuthukise ukusebenza kahle okubandakanya izimboni ezifana nowoyela negesi, ukuhlanza amanzi, i-petrochemical, njll.

Kuyini ukulinganiswa kwamamitha okugeleza?

Ukulinganiswa kwemitha eligelezayo kubhekisela ekulungiseni ukufundwa okusethiwe ngaphambili ukuze kuwele phakathi komkhawulo wephutha elithile. Kungenzeka ukuthi amamitha akhukhuleka ngokuhamba kwesikhathi ngenxa yezimo zokusebenza ezihlukene, okubangela ukuchezuka esilinganisweni ngokwezinga elithile. Izimboni ezifana nemithi noma ukucutshungulwa kwamandla zibeka phambili ukunemba kunezinye izinkambu, ngoba ngisho nokuhluka okuncane kungase kubangele ukungasebenzi, ukumoshwa kwempahla yokusetshenziswa noma izinkinga zokuphepha.

Ukulinganisa okwenziwa abakhiqizi noma ngezinsiza zokulinganisa ezizimele kungaphansi kwamazinga athile emboni, njengamazinga ahlinzekwa yi-National Institute of Standards and Technology (NIST) e-US noma i-Van Swinden Laboratory eYurophu.

Umehluko Phakathi Kokulinganisa Nokulinganisa Kabusha

Ukulinganisa kusho ukulungiswa kokuqala kwemitha yokugeleza kuyilapho ukulinganisa kabusha kuhilela ukulungiswa kabusha ngemva kokusetshenziswa imitha esikhathini esithile. Ukunemba kwemitha yokugeleza kungase kwehle ngokuguga okungavamile okubangelwa ukusebenza ngezikhathi ezithile. Ukulungiswa kabusha okuvamile kubaluleke ngokulinganayo ekulinganisweni kokuqala ohlelweni lwezimboni oluhlukahlukene noluyinkimbinkimbi.

Ukulinganisa kabusha nakho kucabangela kokubili umlando wokusebenza kanye nemiphumela yemvelo. Zombili izinyathelo zivikela ukucutshungulwa nokukhiqizwa okukhulu nokuyinkimbinkimbi kusukela ekungasebenzi kahle, amaphutha nokuchezuka.

Izindlela Zokulinganisa Imitha Yokugeleza

Izindlela ezimbalwa mayelana nendlela yokulinganisa ama-flow metres sezisungulwe kahle, ngokuya ngezinhlobo zoketshezi namamitha. Izindlela ezinjalo ziqinisekisa ukusebenza kwama-flow metres ngokulandela izindinganiso ezithile ezichazwe ngaphambilini.

Ukuqhathanisa Phakathi Kwamamitha Okugeleza Okubili

Imitha yokugeleza okufanele ilinganiswe ibekwe ochungechungeni olunembe ngokulandela izindinganiso ezithile. Ukufundwa kwawo womabili amamitha kuyaqhathaniswa lapho kuhlolwa umthamo owaziwayo woketshezi. Ukulungiswa okudingekayo kuzokwenziwa ngokuya ngemitha yokugeleza eyaziwayo enembile uma kwenzeka kuba nokuchezuka ngaphandle kwemajini evamile. Le ndlela ingase isetshenziselwe ukulinganisai-electromagnetic flow meter.

I-Gravimetric Calibration

Inani elithile loketshezi ngesikhathi esimisiwe liyakalwa, bese lifika ekuqhathanisweni phakathi kokufunda nomphumela obaliwe. I-aliquot yoketshezi ifakwa kumitha yokuhlola bese ikala uketshezi ngesikhathi seyunithi eyaziwa njengemizuzwana engamashumi ayisithupha. Bala izinga lokugeleza kalula ngokuhlukanisa ivolumu ngesikhathi. Qinisekisa ukuthi umehluko phakathi komphumela obaliwe nokufunda uwela ngaphakathi kwemajini evunyelwe. Uma kungenjalo, lungisa imitha bese ushiya ukufundwa ebangeni elamukelekile. Indlela isetshenziselwa ukulinganisaimitha yokugeleza okukhulu.

I-Piston Prover Calibration

I-piston prover calibration ifanele ukulinganiswa kweamamitha okugeleza komoya, kusetshenziswa ipiston enevolumu yangaphakathi eyaziwayo ukuphoqa inani elithile loketshezi ngemitha yokugeleza. Linganisa umthamo woketshezi oluya phambili ku-piston prover. Bese uqhathanisa ukufundwa okubonisiwe nevolumu eyaziwayo bese ulungisa ngokufanele uma kunesidingo.

Ukubaluleka Kokulinganisa Kabusha

Ukunemba kwemitha yokugeleza kungase kunciphe ngokuhamba kwesikhathi ezinhlelweni zokucubungula ezinkulu neziyinkimbinkimbi njengemithi, i-aerospace, amandla nokwelashwa kwamanzi. Ukulahlekelwa kwenzuzo kanye nokulimala kwemishini kungase kudalwe ukulinganiswa kokugeleza okunganembile, okukhiqiza imiphumela eqondile ezindlekweni kanye nenzuzo.

Amamitha okugeleza asetshenziselwa ukuthola ukuvuza kwesistimu angase anganikezi ukufundwa okunembayo okwanele ukuze kuhlonzwe ngokunembile ukuvuza noma ukungasebenzi kahle kwemishini, njengalokho okuvame ukutholakala embonini kawoyela negesi noma izinhlelo zamanzi zikamasipala.

Izinselele Okubhekana Nazo Lapho Ulinganisa Imitha Egelezayo

Ukulinganisa amamitha okugeleza kungafika nezinselele, njengokuhluka kwezakhiwo eziwuketshezi, imiphumela yokushisa, nezinguquko zemvelo. Ukwengeza, iphutha lomuntu ngesikhathi sokulinganisa okwenziwa ngesandla lingadala ukungalungi. Amathuluzi e-automation namathuluzi esofthiwe athuthukile aya ngokuya esetshenziswa ukuze kuthuthukiswe ukunemba kokulinganisa, anikeze impendulo yesikhathi sangempela kanye nokulungiswa okusekelwe kudatha yokusebenza.
