Indlela Yokulinganisa I-Flowmeter

I-Flowmeter iwuhlobo lwemishini yokuhlola esetshenziselwa ukukala ukugeleza koketshezi lwenqubo negesi ezitshalweni nasezikhungweni zezimboni.Ama-flowmeters ajwayelekile yi-electromagnetic flowmeter, flowmeter mass, turbine flowmeter, vortex flowmeter, orifice flowmeter, Ultrasonic flowmeter.Izinga lokugeleza lisho isivinini lapho uketshezi lwenqubo ludlula khona epayipini, emgodini, noma esitsheni ngesikhathi esithile.Onjiniyela bokulawula nezinsimbi bakala leli nani ukuze baqaphe futhi balungise isivinini nokusebenza kahle kwezinqubo nezisetshenziswa zezimboni.

Okufanelekile, okokusebenza kokuhlola kufanele “kusethwe kabusha” ngezikhathi ezithile ukuze kuvinjelwe ukufundwa okungalungile.Kodwa-ke, ngenxa yokuguga kwezingxenye ze-elekthronikhi kanye nokuphambuka kwe-coefficient, endaweni yezimboni, i-flowmeter izolinganiswa njalo ukuze kuqinisekiswe ukunemba kokulinganisa, ukuze kusetshenziswe ngokuphepha nangesikhathi esifanele.

Iyini i-Flowmeter Calibrate?

Ukulinganisa i-Flowmeter kuyinqubo yokuqhathanisa isikali esisethiwe se-flowmeter nesikali sokulinganisa esijwayelekile kanye nokulungisa ukulinganisa kwaso ukuze sivumelane nezinga.Ukulinganisa kuyisici esibalulekile sokusebenzisa izinsimbi ezimbonini eziningi ezidinga ukunemba okuphezulu, njengakuwoyela negesi, i-petrochemical, kanye nokukhiqiza.Kwezinye izimboni ezifana namanzi nendle, ukudla nesiphuzo, izimayini nezensimbi, ukulinganisa okunembe kakhudlwana kuyadingeka ukuze kuqinisekiswe ukusebenza kahle kokukhiqiza.

Amamitha okugeleza alinganiswa ngokuqhathanisa nokulungisa ukulinganisa kwawo ukuze ahlangabezane namazinga achazwe ngaphambilini.Abakhiqizi be-Flowmeter ngokuvamile balinganisa imikhiqizo yabo ngaphakathi ngemva kokukhiqizwa, noma bayithumele ezindaweni ezizimele zokulinganisa ukuze zilungiswe.

Ukulinganisa I-Flowmeter vs. Ukulinganisa

I-Flowmeter Calibration ihlanganisa ukuqhathanisa inani elilinganiselwe le-flowmeter egijimayo neledivayisi yokulinganisa ukugeleza okujwayelekile ngaphansi kwezimo ezifanayo, kanye nokulungisa isikali se-flowmeter ukuze sisondele ezingeni.

I-Flowmeter Recalibration ihlanganisa ukulinganisa i-flowmeter esivele isetshenziswa.Ukulungiswa kabusha kwezikhathi kubalulekile ngoba ukufundwa kwamamitha okugeleza ngokuvamile "kuzophuma esigabeni" ngokuhamba kwesikhathi ngenxa yezimo eziguquguqukayo ezihilelekile ezinqubweni zezimboni.

Umehluko omkhulu phakathi kwalezi zinqubo ezimbili ukuthi ukulinganisa kokugeleza kwenziwa ngaphambi kokuba i-flowmeter ithunyelwe ukuze isetshenziswe, kuyilapho ukulinganisa kabusha kwenziwa ngemva kokuba i-flowmeter isisebenze isikhathi esithile.Amathuluzi esoftware angasetshenziswa futhi ukuze kuqinisekiswe ukunemba kwesilinganiso ngemuva kokuthi i-flowmeter isikaliwe.

Indlela Yokulinganisa I-Flowmeter

Ezinye zezinqubo zokulinganisa amamitha okugeleza asetshenziswa kakhulu yilezi:

• I-Master Meter Calibration
• I-Gravimetric Calibration
• I-Piston Prover Calibration

Izinqubo Zokulinganiswa Kwemitha Enkulu

Ukulinganisa kwe-flowmeter okuyinhloko kuqhathanisa inani elilinganiselwe le-flowmeter elinganisiwe nenani elilinganiselwe le-flowmeter elinganiselwe noma i-flowmeter "eyinhloko" esebenza ngaphansi kwezinga lokugeleza elidingekayo, futhi ilungisa ukulinganisa kwayo ngokufanele.I-flowmeter eyinhloko imvamisa iyithuluzi ukulinganisa kwalo kusethelwe ezingeni likazwelonke noma lamazwe ngamazwe.

Ukwenza ukulinganisa imitha eyinhloko:

• Xhuma ithuluzi eliyinhloko ochungechungeni ne-flow meter ngaphansi kokuhlolwa.
• Sebenzisa umthamo owuketshezi okaliwe ukuze uqhathanise ukufundwa kwemitha yokugeleza eyinhloko kanye nemitha yokugeleza.
• Linganisa imitha yokugeleza ngaphansi kokuhlolwa ukuze ihambisane nokulinganiswa kwemitha yokugeleza eyinhloko.

Inzuzo:

• Kulula ukusebenza, ukuhlola okuqhubekayo.

Izinqubo Zokulinganisa I-Gravimetric

Ukulinganisa isisindo kungenye yezinqubo zokulinganisa umthamo wamamitha wokugeleza kwevolumu enemba kakhulu futhi engabizi kakhulu.Indlela ye-gravimetric ilungele ukulinganiswa kwama-flowmeters oketshezi ku-petroleum, ukuhlanzwa kwamanzi kanye nezimboni ze-petrochemical.

Ukwenza ukulinganisa isisindo:

• Faka i-aliquot (ingxenye encane) yoketshezi lwenqubo kumitha yokuhlola bese uyikale ngesikhathi esinembile ngenkathi igeleza imizuzwana engama-60.
• Sebenzisa isikali esilinganisiwe ukuze ulinganise ngokunembile isisindo soketshezi lokuhlola.
• Ngemuva kokuthi isikhathi sokuhlola sesiphelile, dlulisela uketshezi lokuhlola esitsheni sokudonsa amanzi.
• Izinga lokugeleza kwe-aliquot litholwa ngokuhlukanisa isisindo sevolumu yayo ngesikhathi sokuhlolwa.
• Qhathanisa izinga lokugeleza elibaliwe nezinga lokugeleza lemitha yokugeleza, futhi wenze izinguquko ngokusekelwe enanini langempela lokugeleza elikaliwe.

Inzuzo:

• Ukunemba okuphezulu(Imitha eyinhloko ibuye isebenzise ukulinganisa kwe-gravimetric, ngakho-ke ukunemba okuphezulu kunomkhawulo).

Izinqubo Zokulinganisa I-Piston Prover

Enqubweni yokulinganisa imitha yokugeleza ye-piston calibrator, umthamo owaziwayo woketshezi uphoqelelwa kumitha yokugeleza ngaphansi kokuhlolwa.I-piston calibrator iyisilinda esinobubanzi bangaphakathi obaziwayo.

I-piston calibrator iqukethe ipiston ekhiqiza ukugeleza kwevolumu ngokugudluka okuhle.Indlela yokulinganisa i-piston ifaneleka kakhulu ukulinganisa okuphezulu kwe-ultrasonic flowmeter ukulinganisa, ukulinganisa kwe-fuel flowmeter nokulinganiswa kwe-turbine flowmeter.

Ukwenza ukulinganisa kwe-piston calibrator:

• Faka i-aliquot ye-process fluid ku-piston calibrator kanye nemitha yokugeleza ukuze ihlolwe.
• Umthamo woketshezi oluphuma ku-piston calibrator utholakala ngokuphindaphinda ububanzi obungaphakathi bepiston ngobude obuhanjwa yipiston.
• Qhathanisa leli nani nenani elilinganiselwe elitholwe kumitha yokugeleza futhi ulungise ukulinganiswa kwemitha yokugeleza ngokufanele.
