Namhlanje, zonke zethu Transit-Time ultrasonic flow meterszisetyenziselwa umlinganiselo wokuhamba kolwelo kwaye Umbhobho olinganisiweyo kufuneka ube ngumbhobho wamanzi ogcweleyo.Ixesha lokuhamba imitha yokuhamba kwamanzi ehlala isetyenziswa kwizityalo zokubonelela ngamanzi, usetyenziso lwe-HVAC, umzi-mveliso wamayeza, umzi-mveliso wokutya, ishishini lesiselo, ishishini lesinyithi kunye nabanye.I-Flowmeter yethu ye-ultrasonic ye-Transit-Time inokwahlulwa ibe yimitha yokuhamba kwe-ultrasonic channel enye, i-Dual-channel ultrasonic flow meter, i-multi-channel ultrasonic flow meter.
Ijelo elinye lokuhamba kwemitha ye-ultrasonicngepere enye yesibambeli okanye sofakelo loluvo
Imijelo ephindwe kabini imitha yokuqukuqela ye-ultrasonickunye nezibini ezimbini ze-clamp kwi-sensors okanye uhlobo lofakelo
Ukufakwa kwe-multi-channel imitha yokuhamba kwe-ultrasonic kunye neeperi ezi-4 zokufakwa kwezinzwa
Zikulungele ukulinganisa ulwelo olucocekileyo, ulwelo olunolwelo oluncinci oluqulathe izinto eziqinileyo,ukuchaneka kunokufikelela kwi-1%, ukuchaneka kwe-dual channel ultrasonic flowmeter inokufikelela kwi-0.5%.
Kwishishini lemichiza, ukucocwa kwamanzi, i-petroleum kunye namanye amashishini aya kusebenzisa ii-flowmeters ukulinganisa iindidi ezahlukeneyo zolwelo, ezifana nolwelo lweekhemikhali, amanzi etephu, amanzi avela kwimizi-mveliso, amanzi amdaka asekhaya njalo njalo.Kwaye kumayeza, ukutya kunye namanye amashishini, ngokuqhelekileyo banemigangatho engqongqo kumgangatho wamanzi ukulinganisa ukuhamba, kufuneka balinganise ukuhamba kwamanzi acocekileyo okanye amanzi ahlambulukileyo, ukuhanjiswa kwamanzi ahlambulukileyo kuya kuba kuphantsi.
Kutheni i-clamp kuhlobo lwexesha lokuhamba nge-ultrasonic flowmeter sesona sisombululo silungileyo sokulinganisa ulwelo olusulungekileyo?
Makhe ndithathe ezinye iindidi zokuqukuqela ezidumileyo njengothelekiso .
1. I-flowmeter yombane
I-electromagnetic flowmeter isekwe kumthetho kaFaraday wokungeniswa kwe-electromagnetic.Isetyenziselwa ukulinganisa ukuhamba kwevolumu yolwelo oluqhubayo kunye ne-conductivity enkulu kune-5μS/cm.Yimitha ye-inductive yokulinganisa ukuhamba komthamo we-conductive medium.
Esi silinganisi-manzi singasetyenziselwa ukulinganisa umthamo wokuhamba komthamo wolwelo olomeleleyo oludlayo olufana neasidi eyomeleleyo kunye nesiseko esomeleleyo kunye nolwelo olululwelo oluqinileyo olukwisigaba esibini olunqunyanyisiweyo olufana nodaka, intlama kunye nentlaka yephepha.Ekubeni i-conductivity yamanzi acocekileyo yi-0.055 μS / cm kuphela, ephantsi kakhulu kune-5μS / cm, kuyacaca ukuba ii-flowmeters ze-electromagnetic azifanelekanga ukulinganisa olu lwelo.
2. I-Flometer ye-turbine
Iimitha zokuhamba kwe-turbine zisebenzisa amandla omatshini olwelo ukujikelezisa i-rotor ngaphakathi komsinga wokuhamba.Isantya sokujikeleza silingana ngokuthe ngqo nesantya solwelo oluhamba ngemitha.
Kuya kubonakala ukuba i-flowmeter ye-injini yokulinganisa ukuhamba koqhagamshelwano, kwaye amanzi acocekileyo aneemfuno eziphezulu zezinto eziphathekayo, ngoko ke eyona nto ibalulekileyo kufuneka isetyenziswe ekwenzeni i-316L, ukusetyenziswa kwe-sanitary clamp joint, iindleko zokuvelisa ngokukhawuleza zanda kakhulu.
3. Vimitha yokuhamba nge-ortex,I-Turbine flowmeter, imitha yokuqukuqela yePD
Iimitha zokuhamba ngeVortex, edla ngokubizwa ngokuba yi-vortex shedding flow meters, sebenzisa isithintelo kumjelo wokuqukuqela ukwenza i-vortices esezantsi eyenziwe ngokutshintshanayo macala omabini othintelo.Njengoko ezi vortices zilahlwa kumqobo, zidala iindawo ezitshintshanayo ezisezantsi neziphezulu zoxinzelelo ezijikeleza kumaza athile ngokuhambelana ngqo nesantya solwelo.Isantya sokuhamba singabalwa ukusuka kwisantya solwelo.
Iimitha zokuhamba ze-turbineUkusetyenziswa ngolwelo kunethiyori elula yokusebenza, njengoko ulwelo lutyhutyha ityhubhu yemitha yokuhamba luchaphazela iincakuba zeinjini yomoya.Iibhleyidi zeinjini yomoya kwirotha zijikwe ukuze ziguqule amandla ukusuka kulwelo oluqukuqelayo ukuya kumandla ajikelezayo.I-shaft ye-rotor ijikeleza kwiibheringi, njengoko isantya samanzi sonyusa i-rotor spins ngokukhawuleza.I-Revolutions ngomzuzu okanye i-RPM ye-rotor ihambelana ngokuthe ngqo kwi-velocity ye-velocity ye-flow flow ngaphakathi kwe-tube ye-flow diameter kwaye oku kuhambelana nomthamo kuluhlu olubanzi.
Iimitha zokuqukuqela ezilungileyosebenzisa ii-impellers ezibini ezinelungelo elilodwa lomenzi wechiza (iigiya) ukulinganisela umthamo wolwelo oluchanekileyo oludlula kwimitha yokuhamba njengoko iigiya zijikeleza.Ezi mitha zokuhamba ziyilelwe ngokukodwa ukulinganisa ngokuchanekileyo ulwelo olujiyileyo olunje ngeereyini, iipolyurethanes, izinto zokuncamathelisa, iipeyinti, kunye neekhemikhali ezahlukeneyo zepetroli.
Ziludidi loqhagamshelwano lomlinganiselo wokuqukuqela kolwelo, ngoko ke ziya kudibana ngqo nolwelo, oluya kungcolisa ulwelo olulinganisiweyo.
4. I-Coriolis Mass Flowmeter
Imitha yokuhambahamba yeCoriolis iqulethe ityhubhu eyenziwa ngamandla kukungcangcazela okusisigxina.Xa i-fluid (igesi okanye i-liquid) idlula kule tyhubhu i-mass flow momentum iya kubangela ukuba utshintsho kwi-tube vibration, ityhubhu iya kuguqula isiphumo sokutshintsha kwesigaba.Olu tshintsho lwesigaba lunokulinganiswa kunye nesiphumo somgca sithathwe ngokulinganayo ukuhamba.
Njengoko umgaqo weCoriolis ulinganisa ukuhamba kobunzima obuzimeleyo kwinto engaphakathi kwityhubhu, inokusetyenziswa ngokuthe ngqo kulo naluphi na ulwelo oluqukuqelayo kuyo - ULWEMI okanye iGAS - ngelixa iimitha zokuhamba kobunzima be-thermal zixhomekeke kwiimpawu ezibonakalayo zolwelo.Ngaphezu koko, ngokuhambelana nokutshintsha kwesigaba sokuphindaphinda phakathi kwe-inlet kunye ne-outlet, kunokwenzeka kwakhona ukulinganisa utshintsho lwangempela kwi-frequency yendalo.Olu tshintsho kwi-frequency luhambelana ngokuthe ngqo kubuninzi bolwelo - kunye nesiphumo somqondiso esongezelelweyo sinokuthathwa.Emva kokulinganisa ireyithi yokuqukuqela kobunzima kunye noxinaniso kunokwenzeka ukuba kufumaneke isantya sokuqukuqela komthamo.
Kule mihla, le mitha ilungile nje ukulinganisa i-200mm okanye ngaphantsi kombhobho wedayamitha, ayinakulinganisa umbhobho omkhulu wedayamitha;Ngaphezu koko, inkulu ngokwentelekiso yobunzima nomthamo, akulula ukuyiphatha.
Ngomlinganiselo ococekileyo wokuhamba kwamanzi, unokukhetha imitha yokuhamba ngokusekwe kule migangatho ilandelayo.
1) Ukukhetha imitha yokuqukuqela yohlobo olungangeneleli kwaye ungadibani ngokuthe ngqo nolwelo olulinganisiweyo ukuqinisekisa ukuba ulwelo alungcolisekanga;
2) I-flowmeter ekhethiweyo kufuneka ikwazi ukulinganisa ulwelo kunye ne-conductivity ephantsi kakhulu.
3) Ufakelo kunye nedatha yokulinganisa ye-flow meter ayiyi kuchaphazeleka ngobubanzi bombhobho olinganisiweyo.
I-clamp yangaphandle kwi-flowmeter ye-ultrasonic luhlobo lwemitha ye-liquid engathintekiyo, inokulinganisa umbhobho ukusuka kwi-20mm ukuya kwi-5000mm, ububanzi obubanzi bombhobho, kwaye ingasetyenziselwa ukulinganisa ulwelo okunzima ukudibanisa kunye nokuqwalaselwa.Ukuchaneka kuphezulu ngokwentelekiso, phantse akukho luphazamiseko lweepropathi zendalo ezahlukeneyo zesiphakathi esilinganisiweyo, ezinje ngokugqwala okuqinileyo, okungaqhubekiyo, okusasazeka ngemitha, okutsha kunye nolwelo oluqhumayo kunye nezinye iingxaki.Ke ngoko, kumlinganiselo wamanzi acocekileyo, siya kuqala sincome i-clamp-on fluid ultrasonic flowmeter ukulinganisa.
Bonisa iimeko zokwenyani zereferensi yakho .
