Uyilinganisa njani iFlowmeter

I-Flowmeter luhlobo lwezixhobo zokuvavanya ezisetyenziselwa ukulinganisa ukuhamba kolwelo lwenkqubo kunye negesi kwizityalo kunye nezibonelelo.Ii-flowmeters eziqhelekileyo yi-electromagnetic flowmeter, flowmeter mass, turbine flowmeter, vortex flowmeter, orifice flowmeter, Ultrasonic flowmeter.Umyinge wokuqukuqela ubhekisa kwisantya apho ulwelo lwenkqubo ludlula khona kumbhobho, indawo ekuphuma kuyo amanzi, okanye isikhongozeli ngexesha elithile.Iinjineli zokulawula kunye nezixhobo zilinganisa eli xabiso ukubeka iliso kunye nokulungelelanisa isantya kunye nokusebenza kakuhle kweenkqubo zoshishino kunye nezixhobo.

Ngokufanelekileyo, izixhobo zokuvavanya kufuneka "zisetwe ngokutsha" amaxesha ngamaxesha ukukhusela ukufundwa okungachanekanga.Nangona kunjalo, ngenxa yokuguga kwamacandelo e-elektroniki kunye nokuphambuka kwe-coefficient, kwindawo yoshishino, i-flowmeter iya kulinganiswa rhoqo ukuze kuqinisekiswe ukuchaneka komlinganiselo, ukwenzela ukuba iqhutywe ngokukhuselekileyo nangexesha elifanelekileyo.

Yintoni i-Flowmeter Calibrate?

Ukulinganisa i-Flowmeter yinkqubo yokuthelekisa isikali esisetwe kwangaphambili se-flowmeter kunye nomlinganiselo oqhelekileyo wokulinganisa kunye nokulungelelanisa umlinganiselo wayo ukuze uhambelane nomgangatho.Ukulinganisa kuyinkalo ebalulekileyo yesixhobo kuluhlu olubanzi lwamashishini afuna imilinganiselo ephezulu yokuchaneka, njengeoli kunye negesi, i-petrochemical, kunye nemveliso.Kwamanye amashishini afana namanzi kunye nogutyulo, ukutya kunye nesiselo, imigodi kunye nesinyithi, umlinganiselo ochanekileyo uyafuneka ukuze kuqinisekiswe ukusebenza kakuhle kwemveliso.

Iimitha ezihambayo zilinganiswe ngokuthelekisa kunye nokulungelelanisa ukulinganisa kwazo ukuhlangabezana nemigangatho echazwe kwangaphambili.Abavelisi be-Flowmeter bahlala belungelelanisa iimveliso zabo ngaphakathi emva kwemveliso, okanye bazithumele kumaziko okulungelelaniswa okuzimeleyo ukuze kulungiswe.

Uhlengahlengiso lweFlowmeter vs. Ulungelelwaniso

I-Flowmeter Calibration ibandakanya ukuthelekisa ixabiso elilinganisiweyo le-flowmeter esebenzayo kunye nesixhobo esiqhelekileyo sokulinganisa ukuhamba phantsi kweemeko ezifanayo, kunye nokulungelelanisa umlinganiselo we-flowmeter ukuba usondele kumgangatho.

I-Flowmeter Recalibration ibandakanya ukulinganisa i-flowmeter esele isetyenziswa.Uhlengahlengiso lwamaxesha ngamaxesha lubalulekile kuba ufundo lwemitha yokuhambahamba luya kuhlala “luphuma kwisigaba” ekuhambeni kwexesha ngenxa yeemeko eziguquguqukayo ezibandakanyekayo kwiinkqubo zamashishini.

Umahluko omkhulu phakathi kwezi nkqubo zimbini kukuba ukulinganisa ukuhamba kwenziwa ngaphambi kokuba i-flowmeter ithunyelwe ukuba isetyenziswe, ngelixa uhlengahlengiso lwenziwa emva kokuba i-flowmeter iqhube ixesha elide.Izixhobo zeSoftware zingasetyenziselwa ukuqinisekisa ukuchaneka komlinganiselo emva kokuba i-flowmeter ilinganiswe.

Uyilinganisa njani iFlowmeter

Ezinye zezona nkqubo zisetyenziswa kakhulu zokulinganisa imitha yombane zezi:

• Ulungelelwaniso lweMetha oluPhambili
• Ulungelelwaniso lweGravimetric
• I-Piston Prover Calibration

IiNkqubo zokuLungelela iimitha eziPhambili

Ukulinganisa okuphambili kwe-flowmeter kuthelekisa ixabiso elilinganisiweyo le-flowmeter elinganisiweyo kunye nexabiso elilinganisiweyo le-flowmeter calibrated okanye "i-main" flowmeter esebenza phantsi komgangatho ofunekayo wokuhamba, kwaye ulungelelanisa ukulinganisa kwayo ngokufanelekileyo.I-flowmeter eyintloko idla ngokuba sisixhobo esinomlinganiselo omiselwe kumgangatho wesizwe okanye wehlabathi.

Ukwenza ulungelelwaniso lwemitha engundoqo:

• Qhagamshela isixhobo esiphambili kuthotho kunye ne-flow meter phantsi kovavanyo.
• Sebenzisa umthamo wolwelo olulinganisiweyo ukuthelekisa ufundo lwemitha yokuqukuqela engundoqo kunye nemitha yokuhambahamba.
• Lungelelanisa imitha yokuhambahamba phantsi kovavanyo ukuthobela ulungelelwaniso lweyona mitha yokuhambahamba ingundoqo.

Inzuzo:

• Kulula ukusebenza, uvavanyo oluqhubekayo.

Iinkqubo zokuLungisa iGravimetric

Ukulinganisa ubunzima yenye yezona ndlela zichanekileyo kwaye zinexabiso eliphantsi kunye nenkqubo yokulinganisa imitha yobunzima.Indlela ye-gravimetric ilungele ukulinganiswa kwee-flowmeters zamanzi kwi-petroleum, ukucocwa kwamanzi kunye namashishini e-petrochemical.

Ukwenza ukulinganisa ubunzima:

• Faka i-aliquot (inxalenye encinci) yenkqubo yolwelo kwimitha yovavanyo kwaye uyilinganise ngexesha elichanekileyo ngelixa lihamba imizuzwana engama-60.
• Sebenzisa isikali esilinganisiweyo ukulinganisa ngokuchanekileyo ubunzima bolwelo lovavanyo.
• Emva kokuba ixesha lokuvavanya liphelile, tshintshela ulwelo lovavanyo kwisitya sombhobho.
• Izinga lokuhamba kwe-aliquot lifunyenwe ngokwahlula ubunzima bomthamo walo ngexesha lovavanyo.
• Thelekisa isantya sokuqukuqela esibaliweyo kunye nesantya sokuqukuqela kwemitha yokuqukuqela, kwaye wenze uhlengahlengiso olusekwe kweyona ndlela ilinganisiweyo yokuqukuqela.

Inzuzo:

• Ukuchaneka okuphezulu(I-master meter ikwasebenzisa i-gravimetric calibration, ngoko ke ukuchaneka okuphezulu kulinganiselwe).

Iinkqubo zePiston Prover Calibration

Kwinkqubo yokulinganisa i-flow meter ye-piston calibrator, umthamo owaziwayo wolwelo unyanzeliswa kwi-flow meter phantsi kovavanyo.I-piston calibrator sisixhobo se-cylindrical esinobubanzi obungaphakathi obaziwayo.

I-piston calibrator iqulethe ipiston eyenza ukuhamba kwevolumu ngokufuduka okulungileyo.Indlela yokulinganisa ipiston ifaneleke kakhulu kwi-high-precision ultrasonic flowmeter calibration, i-fuel flowmeter calibration kunye ne-turbine flowmeter calibration.

Ukwenza ulungelelwaniso lwepiston yecalibrator:

• Faka i-aliquot yolwelo lwenkqubo kwi-piston calibrator kunye ne-flow meter ukuze ivavanywe.
• Umthamo wolwelo olukhutshiweyo kwisikali sepiston ufunyanwa ngokuphindaphinda idiameter yangaphakathi yepiston ngobude obuhambayo ipiston.
• Thelekisa eli xabiso kunye nexabiso elilinganisiweyo elifunyenwe kwi-flow meter kwaye ulungelelanise ukulinganisa kwemitha yokuhamba ngokufanelekileyo.
