Hajoale, tsohle tsa rona Transit-Time ultrasonic flow metresli sebelisetsoa tekanyo ea phallo ea mokelikeli 'me Peipi e lekantsoeng e tlameha ho ba phala e tletseng ea metsi.Methara ea phallo ea metsi ea nako ea transit hangata e sebelisoa lifemeng tsa phepelo ea metsi, ts'ebeliso ea HVAC, feme ea meriana, feme ea lijo, indasteri ea lino, indasteri ea metallurgy le tse ling.Our Transit-Time ultrasonic flowmeter e ka aroloa ka mitha e le 'ngoe ea ultrasonic flow meter, Dual-channel ultrasonic flow meter, multi-channel ultrasonic flow meter.
Single channel ultrasonic flow metere nang le para e le 'ngoe ea li-clamp holim'a kapa ho kenya li-sensor
Likanale tse peli tsa ultrasonic flow metere nang le li-sensor tse peli tsa clamp holim'a kapa tsa mofuta oa ho kenya
Multi-channel insertion ultrasonic flow meter e nang le lipara tse 4 tsa li-sensor tsa ho kenya
Li loketse ho lekanya metsi a hloekileng, metsi a nang le lintho tse ngata tse tiileng,ho nepahala ho ka fihla 1%, ho nepahala ha dual channel ultrasonic flowmeter e ka ba ho fihlela ho 0.5%.
Indastering ea lik'hemik'hale, ho hloekisa metsi, peterole le liindasteri tse ling li tla sebelisa li-flowmeters ho lekanya mefuta e mengata ea metsi, joalo ka metsi a lik'hemik'hale, metsi a pompo, metsi a indasteri, metsi a litšila a malapeng joalo-joalo.'Me meriana, lijo le liindasteri tse ling, hangata li na le litekanyetso tse tiileng tsa boleng ba metsi bakeng sa tekanyo ea phallo , ba hloka ho lekanya ho phalla ha metsi a hloekileng kapa metsi a hloekileng haholo, conductivity ea metsi a hloekileng e tla ba e fokolang.
Ke hobane'ng ha ho koala nako ea ho tsamaea ka nako ea ultrasonic flowmeter ke tharollo e molemohali ea ho lekanya mokelikeli o hloekileng?
E re ke nke mefuta e meng e tsebahalang ea phallo meter e le papiso .
1. Electromagnetic flowmeter
The electromagnetic flowmeter e ipapisitse le molao oa Faraday oa induction ea motlakase.E sebelisoa ho lekanya phallo ea molumo oa mokelikeli oa conductive o nang le conductivity e kholo ho feta 5μS/cm.Ke meter e nang le inductive bakeng sa ho lekanya phallo ea molumo oa conductive medium.
Methara ena e ka sebelisoa ho lekanya phallo ea molumo oa mokelikeli o matla o senyang joalo ka asiti e matla le setsi se matla le mokelikeli o tiileng oa mekhahlelo e 'meli o emisitsoeng joalo ka seretse, makhasi le makhasi a pampiri.Kaha conductivity ea metsi a hloekileng ke 0.055 μS / cm feela, e tlase haholo ho feta 5μS / cm, ho hlakile hore li-flowmeters tsa motlakase ha lia lokela ho lekanya mokelikeli ona.
2. Turbine flowmeter
Limithara tsa phallo ea turbine li sebelisa matla a mochini a mokelikeli ho potoloha rotor ka har'a molapo o phallang.Lebelo la ho potoloha le lekana ka kotloloho le lebelo la mokelikeli o tsamaeang ka methareng.
Ho ka bonoa hore phallo ea turbine ke tekanyo ea phallo ea ho ikopanya, 'me metsi a hloekileng a na le litlhoko tse phahameng haholo tsa thepa, kahoo thepa e ka sehloohong e tlameha ho sebelisoa ha ho etsoa 316L, tšebeliso ea motsoako oa bohloeki, litšenyehelo tsa tlhahiso hang-hang li ile tsa eketseha haholo.
3. Vortex flow meter, Turbine flowmeter, PD flow meter
Limithara tsa phallo ea Vortex, eo hangata e bitsoang li-vortex shedding flow metres, e sebelisa tšitiso ho phallo ea metsi ho theha maqhubu a theohileng a theohileng ka lehlakoreng le leng la tšitiso.Ha li-vortices tsena li tsoa tšitisong, li theha libaka tse fapanyetsanoang tse tlase le tse nang le khatello e phahameng tse tsamaeang ka maqhubu a itseng ka ho toba le lebelo la mokelikeli.Sekhahla sa phallo se ka baloa ho tloha ka lebelo la mokelikeli.
Limithara tsa phallo ea turbineBakeng sa ho sebelisoa le lino, ho na le khopolo e bonolo ea ts'ebetso, ha mokelikeli o phalla ka har'a tšupu ea "flow meter" o ama matla a turbine.Maqhubu a turbine a rotor a sothehile ho fetola matla ho tloha mokelikeli o phallang ho ea matla a potolohang.The shaft ea rotor e potoloha holim'a li-bearings, ha lebelo la mokelikeli le eketsa ho potoloha ha rotor ka potlako.Liphetoho ka motsotso kapa RPM ea rotor e lekana ka ho toba le lebelo la phallo e bolelang ka har'a bophara ba tube ea phallo 'me sena se amana le molumo holim'a mefuta e mengata.
Positive displacement flow metressebelisa li-impeller tse peli tse nang le tokelo ea molao (li-gear) ho lekanya palo e nepahetseng ea metsi a fetang har'a methara ea phallo ha likere li ntse li potoloha.Limithara tsena tsa phallo li etselitsoe ho lekanya ka nepo maro a teteaneng joalo ka resin, polyurethanes, likhomaretsi, lipente le lik'hemik'hale tse fapaneng tsa peterole.
Ke tekanyo ea phallo ea mokelikeli oa mofuta oa ho kopana, kahoo ba tla kopana ka kotloloho le mokelikeli, o tla silafatsa mokelikeli o lekantsoeng.
4. Coriolis Mass Flowmeter
Methara ea phallo ea Coriolis e na le tšupu e matlafatsoang ke ho thothomela ho tsitsitseng.Ha mokelikeli (khase kapa mokelikeli) o feta ka har'a tube ena matla a phallo ea boima a tla baka phetoho ho sisinyeha ha tube, tube e tla sotheha ho fella ka phetoho ea mohato.Phetoho ea mohato ona e ka lekanyetsoa 'me tlhahiso ea linear e nkiloeng ka tekanyo ea ho phalla.
Joalo ka ha molao-motheo oa Coriolis o lekanya phallo ea boima e ikemetseng ntle le se ka har'a tube, e ka sebelisoa ka kotloloho ho mokelikeli ofe kapa ofe o phallang ho eona - LIQUID kapa GAS - athe limithara tsa phallo ea boima ba mocheso li ipapisitse le thepa ea 'mele ea mokelikeli.Ho feta moo, ka ho tsamaisana le ho fetoha ha mekhahlelo pakeng tsa ho kena le ho tsoa, hoa khoneha ho lekanya phetoho ea 'nete ea maqhubu a tlhaho.Phetoho ena ea maqhubu a lekana ka ho toba le boima ba mokelikeli - 'me ho ka fumanoa tlhahiso e eketsehileng ea pontšo.Ka mor'a ho lekanya lebelo la phallo ea bongata le boima ba 'mele hoa khoneha ho fumana sekhahla sa phallo ea molumo.
Matsatsing ana, mithara ena e lokile ho lekanya phala ea bophara ba 200mm kapa ka tlase, ha e khone ho lekanya phala e kholo ea bophara;Ho feta moo, e batla e le khōlō ka boima ba 'mele le bophahamo ba eona, ha ho bonolo ho e tšoara.
Bakeng sa tekanyo e hloekileng ea phallo ea metsi, o ka khetha meter ea phallo ho latela litekanyetso tse latelang.
1) Ho khetha meter ea phallo ea metsi e sa senyeheng le ho se kopane ka kotloloho le mokelikeli o lekantsoeng ho netefatsa hore mokelikeli ha o na tšoaetso;
2) Flowmeter e khethiloeng e tlameha ho khona ho lekanya metsi ka conductivity e tlase haholo.
3) Lintlha tsa ho kenya le ho lekanya tsa meter ea phallo li ke ke tsa ameha ka bophara ba phala e lekantsoeng.
External clamp on ultrasonic flowmeter ke mofuta oa meter ea phallo ea metsi e sa amaneng, e ka lekanya phala ho tloha ho 20mm ho isa ho 5000mm, bophara bo boholo ba pipe, hape e ka sebelisoa ho lekanya metsi ao ho leng thata ho kopana le ho a shebella.Ho nepahala ho batla ho phahame, hoo e ka bang ha ho na tšitiso ea thepa e sa tšoaneng ea 'mele ea seaplane e lekantsoeng, e kang matla a senyang, a sa tsitsang, a mahlaseli a kotsi, a tukang le a phatlohang le mathata a mang.Ka hona, bakeng sa tekanyo ea metsi a hloekileng, re tla qala ka ho khothaletsa clamp-on fluid ultrasonic flowmeter ho lekanya.
