Flowmeter ke mofuta oa lisebelisoa tsa liteko tse sebelisetsoang ho lekanya phallo ea mokelikeli oa tšebetso le khase ho limela le litsing tsa indasteri.Li-flowmeters tse tloaelehileng ke electromagnetic flowmeter, flowmeter ea boima, turbine flowmeter, vortex flowmeter, orifice flowmeter, Ultrasonic flowmeter.Sekhahla sa phallo se bolela lebelo leo mokelikeli o fetang peiping, orifice, kapa setshelo ka nako e itseng.Baenjiniere ba taolo le lisebelisoa ba lekanya boleng bona ho lekola le ho lokisa lebelo le katleho ea lits'ebetso le lisebelisoa tsa indasteri.
Ka mokhoa o nepahetseng, lisebelisoa tsa tlhahlobo li tlameha ho "setšoa bocha" nako le nako ho thibela ho bala ho sa nepahalang.Leha ho le joalo, ka lebaka la botsofali ba likarolo tsa elektronike le ho kheloha ha coefficient, sebakeng sa indasteri, flowmeter e tla lekanyetsoa kamehla ho netefatsa ho nepahala ha tekanyo, e le hore e ka sebetsoa ka mokhoa o sireletsehileng le ka nako e loketseng.
Flowmeter Calibrate ke eng?
Flowmeter calibration ke mokhoa oa ho bapisa sekala se seng se setiloe sa flowmeter le sekala se tloaelehileng sa ho metha le ho lokisa tekanyo ea eona hore e lumellane le maemo.Calibration ke karolo ea bohlokoa ea lisebelisoa liindastering tse fapaneng tse hlokang litekanyo tse nepahetseng haholo, joalo ka oli le khase, petrochemical, le tlhahiso.Liindastering tse ling tse kang metsi le likhoerekhoere, lijo le lino, merafo le tšepe, ho boetse ho hlokahala tekanyo e nepahetseng haholoanyane ho netefatsa katleho ea tlhahiso.
Limithara tse phallang li lekanyetsoa ka ho bapisa le ho lokisa methara ea tsona ho kopana le maemo a boletsoeng esale pele.Baetsi ba Flowmeter hangata ba lekanya lihlahisoa tsa bona ka hare ka mor'a tlhahiso, kapa ba li romela litsing tse ikemetseng tsa calibration hore li lokisoe.
Phatlalatso ea Flowmeter vs. Calibration
Flowmeter Calibration e kenyelletsa ho bapisa tekanyo e lekantsoeng ea flowmeter e mathang le ea mochine o tloaelehileng oa ho lekanya phallo tlas'a maemo a tšoanang, le ho lokisa tekanyo ea phallo hore e be haufi le maemo.
Flowmeter Recalibration e kenyelletsa ho lekanya flowmeter e seng e ntse e sebelisoa.Phetoho ea nako le nako e bohlokoa hobane lipalo tsa methapo ea phallo hangata li tla "tsoa" ha nako e ntse e ea ka lebaka la maemo a fapaneng a amehang lits'ebetsong tsa indasteri.
Phapang e kholo pakeng tsa mekhoa ena e 'meli ke hore phallo ea phallo e etsoa pele phallo e romelloa hore e sebelisoe, ha ho tsosolosoa ho etsoa ka mor'a hore flowmeter e sebetse ka nako e itseng.Lisebelisoa tsa software li ka boela tsa sebelisoa ho netefatsa ho nepahala ha tekanyo ka mor'a hore flowmeter e lekanyetsoe.
Mokhoa oa ho lekanya Flowmeter
Tse ling tsa mekhoa e sebelisoang haholo ea ho lekanya li-flow meter ke:
- Tekanyetso ea Metara e Mang
- Gravimetric Calibration
- Piston Prover Calibration
Mekhoa e Metle ea Tekanyo ea Metara
Phallo e kholo ea phallo e bapisa tekanyo e lekantsoeng ea phallo e lekantsoeng le tekanyo e lekantsoeng ea "calibrated flowmeter" kapa "main" flowmeter e sebetsang tlas'a tekanyo e hlokahalang ea phallo, 'me e fetola tekanyo ea eona ka tsela e nepahetseng.Flowmeter e kholo hangata ke sesebelisoa seo calibration ea sona e behiloeng ho maemo a naha kapa a machaba.
Ho etsa calibration ea meter e kholo:
- Kopanya sesebelisoa se seholo letotong le phallo meter tlas'a teko.
- Sebelisa molumo oa mokelikeli o lekantsoeng ho bapisa lipalo tsa metha e kholo ea phallo le meter ea phallo.
- Lekanya meter ea phallo tlas'a teko ho tsamaisana le tekanyo ea meter ea phallo e kholo.
Molemo:
- Ho bonolo ho sebetsa, tlhahlobo e tsoelang pele.
Mekhoa ea Tekanyo ea Gravimetric
Ho lekanya boima ba 'mele ke e' ngoe ea mekhoa e nepahetseng ka ho fetisisa le e bolokang chelete e ngata le mekhoa ea ho lekanya methara ea phallo ea boima.Mokhoa oa gravimetric o loketse ho lekanya li-flowmeters tsa metsi ka har'a peterole, tlhoekiso ea metsi le liindasteri tsa petrochemical.
Ho etsa calibration boima:
- Beha aliquot (karolo e nyane) ea mokelikeli oa ts'ebetso ka har'a mitha ea teko 'me u e lekanye ka nako e nepahetseng ha e ntse e phalla metsotsoana e 60.
- Sebelisa sekala se lekantsoeng ho lekanya boima ba mokelikeli oa teko ka nepo.
- Ka mor'a hore nako ea teko e fete, fetisetsa mokelikeli oa teko ho setshelo sa drain.
- Sekhahla sa phallo ea aliquot se fumanoa ka ho arola boima ba boima ba eona ka nako ea teko.
- Bapisa sekhahla sa phallo se baloang le sekhahla sa phallo ea meter ea phallo, 'me u etse liphetoho ho latela sekhahla sa phallo se lekantsoeng.
Molemo:
- Ho nepahala ho phahameng (Metara e kholo e boetse e sebelisa matla a gravimetric, ka hona, ho nepahala ho phahameng ka ho fetisisa ho na le moeli).
Lits'ebetso tsa Tekanyo ea Piston Prover
Ts'ebetsong ea ho lekanya methara ea phallo ea calibrator ea piston, molumo o tsejoang oa mokelikeli o qobelloang ho mitha ea phallo tlas'a teko.Piston calibrator ke sesebelisoa sa cylindrical se nang le bophara bo ka hare bo tsejoang.
Piston calibrator e na le piston e hlahisang molumo oa molumo ka phallo e ntle.Mokhoa oa ho lekanya piston o loketse haholo bakeng sa phallo e phahameng ea ultrasonic flowmeter calibration, peterole flowmeter calibration le turbine flowmeter calibration.
Ho etsa calibrator ea piston:
- Kenya aliquot ea mokelikeli oa tšebetso ka har'a calibrator ea piston le phallo meter hore e lekoe.
- Bophahamo ba mokelikeli o tsoang piston calibrator bo fumanoa ka ho atisa bophara ba ka hare ba piston ka bolelele boo piston e bo tsamaeang.
- Bapisa boleng bona le tekanyo e lekantsoeng e fumanoang ho tloha ho meter ea phallo 'me u lokise tekanyo ea meter ea phallo ho latela.
