Tam sim no, peb txhua tus Transit-Time ultrasonic flow meteryog siv rau kev ntsuas dej ntws thiab cov yeeb nkab ntsuas yuav tsum yog cov kav dej puv.Transit time kua flow meter feem ntau siv rau hauv cov chaw muab dej, HVAC daim ntawv thov, chaw tsim tshuaj, khoom noj khoom haus, kev lag luam dej haus, kev lag luam metallurgy thiab lwm yam.Peb Transit-Time ultrasonic flowmeter tuaj yeem muab faib ua ib qho channel ultrasonic flow meter, Dual-channel ultrasonic flow meter, multi-channel ultrasonic flow meter.
Ib channel ultrasonic flow meternrog ib khub ntawm clamp rau los yog ntxig sensors
Ob chav channel ultrasonic flow meternrog ob khub ntawm clamp rau lossis ntxig hom sensors
Multi-channel insertion ultrasonic flow meter nrog 4 khub ntawm insertion sensors
Lawv tsim nyog rau kev ntsuas cov kua dej huv, cov kua dej uas muaj cov khib nyiab tsawg,Qhov tseeb tuaj yeem ncav cuag 1%, qhov tseeb ntawm dual channel ultrasonic flowmeter tuaj yeem nce mus txog 0.5%.
Hauv kev lag luam tshuaj, kev kho dej, roj av thiab lwm yam kev lag luam yuav siv cov flowmeters los ntsuas ntau yam kua, xws li cov kua tshuaj, dej kais dej, dej hauv tsev, dej khib nyiab thiab lwm yam.Thiab hauv cov tshuaj, zaub mov thiab lwm yam lag luam, lawv feem ntau muaj cov qauv nruj hauv cov dej zoo rau kev ntsuas dej ntws, lawv yuav tsum ntsuas qhov ntws ntawm cov dej ntshiab lossis dej ntshiab ultra, dej ntshiab conductivity yuav tsawg.
Vim li cas clamp ntawm hom hla lub sij hawm ultrasonic flowmeter yog qhov zoo tshaj plaws los ntsuas cov kua ntshiab?
Cia kuv coj ib co lwm yam nrov flow meter raws li kev sib piv.
1. Electromagnetic flowmeter
Lub electromagnetic flowmeter yog raws li Faraday txoj cai ntawm electromagnetic induction.Nws yog siv los ntsuas qhov ntim ntawm cov kua conductive nrog conductivity ntau dua 5μS / cm.Nws yog ib qho inductive meter rau ntsuas qhov ntim ntws ntawm cov khoom nruab nrab.
Qhov ntsuas no tuaj yeem siv los ntsuas qhov ntim ntawm cov kua muaj zog corrosive xws li cov kua qaub thiab lub hauv paus muaj zog thiab homogeneous kua-khoom ob-theem tshem tawm cov kua xws li av nkos, pulp thiab ntawv pulp.Txij li thaum lub conductivity ntawm cov dej ntshiab tsuas yog 0.055 μS / cm, qis dua 5μS / cm, nws yog pom tseeb tias electromagnetic flowmeters tsis haum rau kev ntsuas ntawm cov kua no.
2. Turbine flowmeter
Turbine flow meters siv lub zog txhua yam ntawm cov kua los tig lub rotor hauv cov dej ntws.Kev sib hloov ceev yog ncaj qha proportional rau qhov tshaj tawm ntawm cov kua mus los ntawm lub 'meter'.
Nws tuaj yeem pom tau tias lub turbine flowmeter yog qhov ntsuas kev sib cuag, thiab cov dej ntshiab muaj cov khoom siv siab tshwj xeeb, yog li cov khoom tseem ceeb yuav tsum tau siv rau hauv kev tsim khoom ntawm 316L, kev siv cov khoom siv huv si, cov nqi tsim khoom tam sim ntawd nce ntau heev.
3. VOrtex flow meter, Turbine flowmeter, PD flow meter
Vortex flowmeter, feem ntau hu ua vortex shedding flow meters, siv ib qho kev cuam tshuam hauv cov kwj deg los tsim cov vortex downstream uas tau hloov pauv ntawm ob sab ntawm qhov kev cuam tshuam.Raws li cov vortices no tau los ntawm kev cuam tshuam, lawv tsim alternating low and high-pressure azones that oscillate at particular frequencies ncaj qha proportional to the speed of the fluidity.Tus nqi ntws tuaj yeem xam los ntawm cov kua dej tawm.
Turbine flowmeterKev siv cov kua dej muaj qhov kev xav yooj yim ntawm kev ua haujlwm, raws li cov kua ntws los ntawm lub raj ntawm cov ntsuas ntsuas nws cuam tshuam rau cov hniav turbine.Lub turbine hniav ntawm lub rotor yog angled los hloov lub zog ntawm cov kua ntws mus rau hauv lub zog tig.Cov ncej ntawm lub rotor spines ntawm bearings, raws li cov kua tshaj tawm nce lub rotor spin proportionally sai dua.Revolutions ib feeb los yog RPM ntawm lub rotor yog ncaj qha proportional rau qhov nruab nrab ntws tshaj tawm nyob rau hauv lub ndlwg raj txoj kab uas hla thiab qhov no muaj feem xyuam rau lub ntim ntawm ntau yam.
Qhov zoo ntawm kev hloov pauv flowmetersiv ob lub impellers patented (lub zog) los ntsuas qhov ntim ntawm cov kua uas dhau los ntawm cov ntsuas ntws raws li lub zog tig.Cov ntsuas ntsuas no tau tsim tshwj xeeb los ntsuas cov kua dej tuab xws li cov resins, polyurethanes, nplaum, xim, thiab ntau yam petrochemicals.
Lawv yog cov sib cuag hom kua ntws ntsuas, yog li lawv yuav nyob rau hauv kev sib cuag ncaj qha nrog cov kua, uas yuav ua paug cov kua ntsuas.
4. Coriolis Mass Flowmeter
Lub Coriolis flow meter muaj ib lub raj uas muaj zog los ntawm kev co ruaj khov.Thaum cov kua (gas los yog kua) dhau los ntawm lub raj no lub zog ntws ntawm lub zog yuav ua rau muaj kev hloov hauv lub raj vibration, lub raj yuav twist ua rau lub sijhawm hloov.Qhov kev hloov pauv theem no tuaj yeem ntsuas tau thiab cov zis tawm tawm tau muab faib ua qhov sib npaug.
Raws li txoj cai Coriolis ntsuas huab hwm coj ntws ywj pheej ntawm dab tsi nyob hauv lub raj, nws tuaj yeem siv ncaj qha rau cov kua dej uas ntws los ntawm nws - LIQUID lossis GAS - qhov ntsuas kub ntawm qhov ntsuas kub yog nyob ntawm lub cev ntawm cov kua dej.Tsis tas li ntawd, nyob rau hauv parallel nrog rau theem hloov nyob rau hauv zaus ntawm inlet thiab qhov hluav taws xob, nws kuj tseem ua tau los ntsuas qhov tseeb hloov nyob rau hauv ntuj zaus.Qhov kev hloov pauv ntawm qhov zaus no yog nyob rau hauv qhov sib piv ncaj qha rau qhov ntom ntawm cov kua dej - thiab cov teeb liab ntxiv tuaj yeem muab tau.Tom qab ntsuas ob qhov loj txaus tus nqi thiab qhov ceev nws muaj peev xwm muab tau qhov ntim ntws tus nqi.
Niaj hnub no, lub 'meter' no tsuas yog ua tau los ntsuas 200mm lossis hauv qab txoj kab uas hla, tsis tuaj yeem ntsuas cov kab loj loj;Ntxiv mus, nws yog qhov loj hauv qhov hnyav thiab ntim, tsis yooj yim rau lis.
Rau kev ntsuas dej ntshiab, koj tuaj yeem xaiv cov ntsuas ntsuas raws li cov qauv hauv qab no.
1) Txhawm rau xaiv cov dej ntws tsis sib haum thiab tsis muaj kev sib cuag ncaj qha nrog cov kua ntsuas kom ntseeg tau tias cov kua tsis muaj paug;
2) Lub flowmeter xaiv yuav tsum muaj peev xwm ntsuas cov kua dej uas tsis tshua muaj conductivity.
3) Kev teeb tsa thiab ntsuas cov ntaub ntawv ntawm cov ntsuas ntws yuav tsum tsis txhob cuam tshuam los ntawm txoj kab uas hla ntawm cov yeeb nkab ntsuas.
Sab nraud clamp ntawm ultrasonic flowmeter yog ib yam ntawm cov kua dej tsis sib cuag, nws tuaj yeem ntsuas cov yeeb nkab los ntawm 20mm mus rau 5000mm, ntau txoj kab uas hla ntawm cov yeeb nkab, thiab tseem tuaj yeem siv los ntsuas cov kua dej uas nyuaj rau kev sib cuag thiab kev soj ntsuam.Qhov tseeb yog qhov siab, yuav luag tsis muaj kev cuam tshuam ntawm ntau yam khoom ntawm lub cev ntawm qhov ntsuas nruab nrab, xws li muaj zog corrosive, non-conductive, radioactive, flammable thiab explosive kua thiab lwm yam teeb meem.Yog li ntawd, rau kev ntsuas dej ntshiab, peb yuav xub pom zoo rau sab nraud clamp-on kua ultrasonic flowmeter ntsuas.
Qhia qee qhov xwm txheej tiag tiag rau koj siv.
