Ho Utloisisa Seo Li-flowmeter tsa Electromagnetic li se Etsang: Ke Metsi Afe ao li ka a Lekanyang?

Methapo ea motlakase e sebelisoang haholo liindastering tse fapaneng ka lebaka la bokhoni ba tsona ba ho lekanya phallo ea metsi a tsamaisang motlakase ka nepo. Lisebelisoa tsena li tsebahala ka ho tšepahala le ho tenyetseha ha tsona, e leng se etsang hore li lokele mefuta e mengata ea lits'ebetso. Leha ho le joalo, potso e tloaelehileng ke hore, "Methapo ea motlakase e ka lekanya mofuta ofe oa metsi?"

Ho araba potso ena, ho bohlokoa ho utloisisa melao-motheo e ka morao ho li-flowmeter tsa electromagnetic. Lisebelisoa tsena li sebetsa ho latela molao oa Faraday oa induction ea electromagnetic, o bolelang hore ha conductor e feta tšimong ea makenete, motlakase o hlahisoa ka har'a conductor. Ka flowmeter ea electromagnetic, mokelikeli o tsamaisang motlakase o sebetsa e le conductor e tsamaeang 'me matla a makenete a hlahisoa ke li-coil tsa flowmeter. Ka ho lekanya motlakase o susumelitsoeng, flowmeter e ka fumana ka nepo sekhahla sa phallo ea mokelikeli.

Ka lebaka la molao-motheo ona oa ts'ebetso, li-flowmeter tsa motlakase li etselitsoe ka ho khetheha ho lekanya phallo ea li-conductive liquids. Sena se bolela hore mokelikeli o tlameha ho ba le boemo bo itseng ba conductivity hore flowmeter e sebetse hantle. Ka kakaretso, li-liquids tse nang le conductivity e fokolang ea 5 µS/cm (microSiemens ka centimeter) li loketse ho lekanngoa ka li-flowmeter tsa motlakase.

Mehlala e tloaelehileng ea mekelikeli e ka lekanngoang ka li-flow metres tsa motlakase e kenyelletsa metsi, li-acid, li-alkali le litharollo tse fapaneng tsa lik'hemik'hale. Mekelikeli ena hangata e na le maemo a hlokahalang a ho tsamaisa metsi ho netefatsa tekanyo e nepahetseng ea phallo. Ho feta moo, tlhaho e sa hlaseleng ea li-flow metres tsa motlakase e etsa hore li lokele ho sebelisoa le mekelikeli e khorofo kapa e senyang hobane ha ho na likarolo tse tsamaeang kapa litšitiso tse ka senyehang tseleng ea phallo.

Ho bohlokoa ho hlokomela hore leha li-flow meter tsa motlakase li loketse hantle ho lekanya mefuta e fapaneng ea maro a tsamaisang motlakase, ho na le meeli e meng eo u lokelang ho e nahana. Mohlala, maro a nang le conductivity e tlase haholo, joalo ka oli e hloekileng kapa li-hydrocarbon, a kanna a se ke a loketse ho lekanngoa ka flowmeter ea motlakase. Tabeng ena, mahlale a mang a ho lekanya phallo joalo ka li-flow meter tsa ultrasonic kapa tsa thermal mass a ka ba a loketseng haholoanyane.

Ho phaella moo, boteng ba dipululana kapa dikarolwana tse tiileng mokelikeling bo tla ama ho nepahala ha tekanyo ya sesupa-tsela sa phallo ya motlakase. Mokelikeli o lokela ho bolokwa o se na dipululana le ditshila ho fumana ditekanyo tse tshepahalang tsa phallo.

Ka bokhutšoanyane, li-flowmeter tsa motlakase li khona ho lekanya mefuta e fapaneng ea metsi a tsamaisang motlakase, ho kenyeletsoa metsi, li-acid, li-alkali le litharollo tsa lik'hemik'hale. Moralo oa tsona o sa kenelleng le ho nepahala ho hoholo li etsa hore e be khetho e tsebahalang bakeng sa ho lekanya phallo liindastering tse kang kalafo ea metsi, ts'ebetso ea lik'hemik'hale, le tlhahiso ea lijo le lino. Leha ho le joalo, ho bohlokoa ho nahana ka conductivity le bohloeki ba mokelikeli ho netefatsa ts'ebetso e ntle ea flowmeter ea motlakase. Ka ho utloisisa bokhoni le meeli ea flowmeter ea motlakase, basebelisi ba ka etsa qeto e nang le tsebo mabapi le ho tšoaneleha ha bona bakeng sa ts'ebeliso e itseng ea tekanyo ea mokelikeli.
