Ho fumana hore na flowmeter e nepahetse, nahana ka lintlha tsa bohlokoa tse kang mokelikeli o lekantsoeng, sebaka sa phallo, ho nepahala ho hlokahalang le mekhoa ea ts'ebetso.Tataiso ea rona e qaqileng e tla u thusa ho khetha meter ea phallo e nepahetseng ka ho fetesisa ho ntlafatsa lits'ebetso tsa hau tsa indasteri le ho netefatsa tekanyo e nepahetseng ea mokelikeli.
Tataiso e Felletseng ea ho Khetha Metha e nepahetseng ea Phallo
Sehloohong sena, re tla u tataisa molemong oa ho khetha flowmeter e nepahetseng bakeng sa litlhoko tsa hau tse ikhethang.
Hore na o batla flowmeter ho lekanya phallo ea maro, likhase kapa mouoane, re tla u fa leseli lohle leo u le hlokang ho etsa qeto u na le tsebo.
Setsi sa phallo ke eng?
The flow meter ke sesebediswa sa ho metha se sebedisetswang ho fumana bongata ba mokelikeli o phallang ka phaephe.E bohlokoa lits'ebetsong tse ngata tsa indasteri, kaha e lumella ho phalla ha maro hore ho behoe leihlo le ho laoloa.
U ka khetha meter e nepahetseng joang?
Khetho ea meter ea phallo e itšetlehile ka lintlha tse 'maloa, tse kang mofuta oa mokelikeli, mocheso le maemo a khatello ea ts'ebetso, le litšobotsi tsa kopo.Malebela ke ana a tla u thusa ho etsa khetho e nepahetseng:
1.Etsa qeto ea mofuta oa phallo meter e hlokahalang:Ho na le litheknoloji tse fapaneng tsa "flow meter", 'me e' ngoe le e 'ngoe e loketse mefuta e itseng ea mokelikeli.Mahlale a tloaelehileng a kenyelletsa diaphragm, venturi, float, electromagnetic, vortex, ultrasonic, coriolis le li-flowmeters tsa mocheso.Khetha e loketseng kopo ea hau hantle.
2.Ela hloko li-parameter tse khethehileng:Ho khetha meter e nepahetseng ea ho phalla, ela hloko litekanyo tse kang metsi a mangata, khatello, mocheso le ho theoha leha e le efe ea khatello.Lintlha tsena 3.li ka susumetsa hore na flowmeter e sebetsa hantle hakae ts'ebelisong ea hau.
3.Nahana ka litlhoko tsa ho instola:Maemo ao meter ea phallo e kenngoa ho eona a ka ba le tšusumetso ho nepahala le ho sebetsa ha eona.Ela hloko lithibelo tsa ho kenya tse kang ho kobeha ha lipeipi, li-valve le li-constriction.Mefuta e meng ea "flow meter" e ameha haholo ho litšitiso tsena ho feta tse ling.
Ka ho latela malebela ana, u tla khona ho khetha meter ea phallo e lumellanang hantle le litlhoko tsa hau tse ikhethileng.
Kaha joale re se re koahetse lintlha tsa motheo tsa ho khetha meter ea phallo, a re tsoeleng pele ho tlhaloso e qaqileng haholoanyane.
DIAPHRAGM FLOW METER KAPA ORIFICE PATE LE FAPANENG KHATELLO
Methara ea phallo ea khatello e fapaneng le ntho e ka sehloohong e loketse ho lekanya ho phalla ha metsi a hloekileng le likhase, kapa mouoane.E sebelisa khatello e fapaneng e hlahisoang ke mokelikeli o fetang ka har'a sekoti joalo ka orifice plate kapa diaphragm.Khatello e fapaneng e lekanyetsoa ho sebelisoa li-transmitters tsa khatello tse fapaneng ebe li fetoloa lebelo la phallo.
VORTEX PHAPALA METHA
Meta ea phallo ea vortex e loketse ho lekanya ho phalla ha metsi a hloekileng, a qosoang le likhase tse hloekileng.E sebelisa li-vortices tse hlahisoang ke phallo ea mokelikeli ho lekanya phallo.
1. Mofuta oa mokelikeli:Etsa qeto ea hore na mokelikeli o lokelang ho lekanyetsoa ke oa metsi kapa oa khase, o hloekile kapa o qositsoe.Limithara tse ling tsa phallo li loketse hamolemo mefuta e itseng ea mokelikeli.
2.Mocheso le maemo a khatello:Sheba maemo a mocheso le khatello ea ts'ebetso eo meter ea phallo e tla sebelisoa ho eona.Limithara tse ling tsa phallo li na le mocheso o fokolang le mekhahlelo ea khatello.
3.Ho lahleheloa ke khatello ea maikutlo:Limithara tse phallang li ka baka tahlehelo ea khatello tsamaisong.Ho bohlokoa ho ela hloko litahlehelo tsena tsa khatello ho netefatsa hore ts'ebetso ea hau e sebetsa hantle.
4. Tlhokahalo ea tlhaiso-leseling ea phallo:Nahana ka litaba tsa phallo tseo u li hlokang.Na u batla ho lekanya phallo ea molumo kapa phallo ea bongata?Sena se tla itšetleha ka kopo ea hau e khethehileng le lintlha tse hlokahalang bakeng sa ts'ebetso ea hau.
5. Likarolo tsa ho kenya: Nahana ka lithibelo tsa ho kenya tse kang lipeipi tse ikhethang, li-bend, li-valve, joalo-joalo. Methapo e meng ea phallo e ka 'na ea e-ba hlokolosi ho tsena.Limithara tse ling tsa phallo li ka ba le maikutlo a matle ho litšitiso tsena, tse ka amang ho nepahala ha tsona.
Ka ho ela hloko litekanyo tsena, u tla khona ho khetha meter ea phallo e finyellang litlhoko tsa hau tse khethehileng.
