Hadda, dhammaanteen Tareenka-Time mitir socodka socodka ultrasonicwaxaa loo isticmaalaa cabbiraadda socodka dareeraha iyo tuubada la cabbiray waa inay noqotaa tuubo biyo buuxa ah.mitirka socodka dareeraha wakhtiga ku-meel-gaadhka ah oo inta badan lagu isticmaalo dhirta sahayda biyaha, codsiga HVAC, warshadda dawooyinka, warshada cuntada, warshadaha cabitaanka, warshadaha biraha iyo kuwa kale.Mitirka socodka ultrasonic-Time-Time-kayaga waxaa loo qaybin karaa hal kanaal hal kanaal ah mitir socodka ultrasonic, mitirka socodka ultrasonic dual-channel, mitir socodka ultrasonic channel-ka badan.
Hal kanaal halbeegga socodka ultrasonicoo leh hal lammaane oo isku dhejis ah ama gelinta dareeme
mitirka socodka ultrasonic double channeloo leh laba lammaane oo isku dhejis ah ama dareemaha nooca gelinta
Gelida Multi-channel mitir socodka ultrasonic oo leh 4 lammaane ee dareemayaasha gelinta
Waxay ku habboon yihiin cabbirka dareeraha nadiifka ah ee qaraabada ah, dareeraha ay ku yar yihiin adkaha,saxnaanta waxay gaari kartaa 1%, saxnaanta dual channel ultrasonic flowmeter waxay noqon kartaa ilaa 0.5%.
Warshadaha kiimikada, daaweynta biyaha, batroolka iyo warshadaha kale waxay isticmaali doonaan cabbirada dareeraha kala duwan, sida dareeraha kiimikada, biyaha tuubada, biyaha warshadaha, biyaha wasakhda guriga iyo wixii la mid ah.Iyo dawooyinka, cuntada iyo warshadaha kale, waxay inta badan leeyihiin heerar adag tayada biyaha ee cabbiraadda socodka, waxay u baahan yihiin inay cabbiraan socodka biyaha saafiga ah ama biyaha saafiga ah, socodka biyaha saafiga ah wuxuu noqon doonaa mid hooseeya.
Waa maxay sababta loogu dhejiyo nooca wakhtiga gaadiidka ee ultrasonic flowmeterka waa xalka ugu fiican ee lagu cabbiro dareeraha saafiga ah?
Aan u qaato noocyo kale oo caan ah mitirka socodka .
1. Electromagnetic flowmeter
Halbeegga qulqulka korantada wuxuu ku salaysan yahay sharciga Faraday ee kicinta korantada.Waxaa loo isticmaalaa in lagu cabbiro qulqulka mugga dareeraha korantada leh ee korantada ka weyn 5μS/cm.Waa mitir inductive ah oo lagu cabbiro qulqulka mugga dhexdhexaadiyaha.
Mitirkaan waxaa loo isticmaali karaa in lagu cabbiro qulqulka mugga dareeraha wasakhaysan ee xooggan sida aashitada xooggan iyo saldhigga xooggan iyo dareeraha isku midka ah ee dareeraha adag ee laba-waji ah sida dhoobada, saxarka iyo saxarka warqadda.Maaddaama socodka biyaha saafiga ahi uu yahay 0.055 μS/cm oo keliya, aad uga hooseeya 5μS/cm, waxaa cad in dareeraha korantada (electromagnetic flowmeters) aysan ku habboonayn cabbirka dareerahaan.
2. mitirka marawaxadaha
Mitirrada socodka marawaxadaha waxay isticmaalaan tamarta farsamada dareeraha si ay ugu rogaan wareegga qulqulka qulqulka.Xawaaraha wareeggu wuxuu si toos ah ula siman yahay xawaaraha dareeraha ku socda mitirka.
Waxaa la arki karaa in qulqulka marawaxadaha uu yahay cabbirka socodka xiriirka, iyo biyaha saafiga ah waxay leeyihiin shuruudo gaar ah oo aad u sarreeya, sidaas darteed walxaha ugu muhiimsan waa in loo isticmaalo wax soo saarka 316L, isticmaalka wadajirka xajinta nadaafadda, kharashka wax soo saarka isla markiiba kor u kacay.
3. Vmitir socodka ortex, Turbine Flometer, PD socodka mitir
Mitirrada qulqulka Vortex, oo inta badan loo yaqaanno mitirka qulqulka qulqulka qulqulka, isticmaal xannibaad qulqulka qulqulka si aad u abuurto wareegyada hoose kuwaas oo si beddel ah u sameysma labada dhinac ee xannibaadda.Maaddaama wareegyadan laga daadiyo xannibaadda, waxay abuuraan beddelaad hooseeya iyo aagag cadaadis-sare leh kuwaas oo milicsada xawli gaar ah oo si toos ah u dhigma xawaaraha dareeraha.Heerka socodka waxaa laga xisaabin karaa xawaaraha dareeraha.
Mitirrada socodka marawaxadahaIsticmaalka dareeraha waxay leeyihiin aragti hawleed fudud oo fudud, maadaama dareere dhex mara tuubada mitirka socodka wuxuu saameeyaa marawaxadaha marawaxadaha.Mashiinnada marawaxadaha ee rotor-ku waxay u janjeeraan inay tamarta ka beddelaan dareeraha qulqulaya una beddelaan tamar wareeg ah.Shafka rotor-ku wuxuu ku wareegaa xajmiyada, maadaama xawaaraha dareeraha uu kordhiyaa wareegtada si qiyaasan degdeg ah.Kacdoonada daqiiqadii ama RPM rotor-ku waxay si toos ah ula siman yihiin celceliska xawaaraha socodka gudaha dhexroorka tuubada socodka tanina waxay la xidhiidhaa mugga ka badan baaxad balaadhan.
Mitirrada socodka barokaca ee toganKa faa'iidayso laba impellers (gears) patented si aad u cabbirto qiyaasta saxda ah ee dareeraha ee dhex mara mitirka socodka marka gearsku wareego.Mitirradan socodka waxaa si gaar ah loogu talagalay inay si sax ah u cabbiraan dareeraha dhumuc weyn sida resins, polyurethane, dhejisyada, rinjiga, iyo kiimikooyinka batroolka ee kala duwan.
Waxay yihiin cabbirka socodka dareeraha nooca taabashada, markaa waxay si toos ah ula xiriiri doonaan dareeraha, taasoo wasakhayn doonta dareeraha la qiyaasay.
4. Coriolis Mass Flowmeter
Mitirka socodka Coriolis wuxuu ka kooban yahay tuubo ay tamar siiso gariir go'an.Marka dareere (gaas ama dareere) uu dhex maro tuubadan xawliga qulqulka ballaaran wuxuu keeni doonaa isbeddel ku yimaada gariirka tuubada, tuubada ayaa maroojin doonta taasoo keenaysa isbeddel weji ah.Isbedelka wejigan waa la cabbiri karaa oo wax soo saar toos ah ayaa laga soo saaray saamiga socodka.
Sida mabda'a Coriolis u cabbiro qulqulka tirada badan ee ka madax bannaan waxa ku dhex jira tuubada, waxaa si toos ah loogu dabaqi karaa dareere kasta oo dhex socda - LIQUID ama GAAS - halka mitirka socodka kulaylka uu ku xiran yahay sifooyinka jireed ee dareeraha.Intaa waxaa dheer, iyada oo la barbar-dhigo isbeddelka wejiga ee soo noqnoqda inta u dhaxaysa gelitaanka iyo ka bixista, waxa kale oo suurtagal ah in la cabbiro isbeddelka dhabta ah ee soo noqnoqda dabiiciga ah.Isbeddelkan soo noqnoqda ayaa si toos ah ula mid ah cufnaanta dareeraha - waxaana la soo saari karaa calaamad kale.Markaan cabbiray heerka qulqulka tirada badan iyo cufnaanta labadaba waxaa suurtagal ah in la soo saaro heerka qulqulka mugga.
Maalmahan, mitirkani waa ok si loo cabbiro 200mm ama ka hooseeya tuubooyinka dhexroorka, ma cabbiri karo tuubada dhexroorka weyn;Intaa waxaa dheer, waa mid aad u weyn miisaan ahaan iyo mugga, ma fududa in la maareeyo.
Qiyaasta socodka biyaha saafiga ah, waxaad dooran kartaa mitirka socodka iyadoo lagu saleynayo heerarka soo socda.
1) Si loo doorto mitirka socodka biyaha nooca aan fiicneyn oo aan si toos ah ula xiriirin dareeraha la cabbiray si loo hubiyo in dareeruhu aanu wasakhayn;
2).
3) Rakibaadda iyo xogta cabbiraadda mitirka socodka ma saameyn doonto dhexroorka tuubada la cabbiray.
Xakamaynta dibadda ee ultrasonic flowmeter waa nooc ka mid ah mitirka dareeraha dareeraha ah ee aan la xiriirin, waxay cabbiri kartaa tuubada 20mm ilaa 5000mm, dhexroor ballaaran oo tuubo ah, waxaana sidoo kale loo isticmaali karaa in lagu cabbiro dareeraha ay adag tahay in lala xiriiro iyo fiirsashada.Saxnimadu waa mid aad u sareysa, ku dhawaad wax faragalin ah oo ku saabsan sifooyinka jirka ee kala duwan ee dhexdhexaadka la qiyaasay, sida kuwa daxalka leh, aan shaqaynayn, shucaac, dareere guban kara iyo kuwa qarxa iyo dhibaatooyin kale.Sidaa darteed, cabbiraadda biyaha saafiga ah, waxaanu marka hore kugula talin doonaa mitirka dareeraha dareeraha ee ultrasonic si loo cabbiro.
Tus qaar ka mid ah kiisaska dhabta ah ee tixraacaada.
