I le avea ai ma iunite pulea autu, o le mamanu ma le aoga o levortex flowmeterlaupapa matagaluega aafia tuusao le faatinoga o le flowmeter. Faʻavae i luga o le taʻiala galue o le vortex flowmeter (suʻeina o le tafe o le vai e faʻavae i luga o le Karman vortex phenomenon), o le aoga autu o lana laupapa matagaluega e mafai ona aoteleina e pei ona taua i lalo mai vaega o uiga faʻapitoa, faʻatinoga lelei, ma le aoga aoga:
Mauaina sa'o o faailoilo maualuga:
O le laupapa matagaluega e tuʻufaʻatasia le televave o le analog-to-digital conversion (ADC) modules ma le faʻaogaina o faʻailoga numera (DSP), lea e mafai ona puʻeina faʻailoga vaivai (e masani lava o le sefulu i le afe o Hz) faʻatupuina e vortex generators i le taimi moni. E ala i le faʻamamaina, faʻateleina, ma le faʻaitiitia o le pisa algorithms, o le faʻailoga o le mauaina o faʻailoga e faʻamautinoa e itiiti ifo i le 0.1%, faʻafeiloaʻi manaʻoga maualuga-saʻo (e pei o le saʻo fua o le ± 1% R).
Taui le laina ma algorithms atamai:
O le microprocessor fausia (MCU) e mafai ona faʻasaʻo le aʻafiaga o le suavai ma le viscosity suiga i fua o fua e ala i le vevela / mamafa faʻatauga algorithms, faʻafetaui i tulaga faigaluega eseese (e pei o le maualuga o le vevela, maualuga le mamafa, ma le fesuisuiai o auala), ma faʻaleleia le mautu o fuataga i siosiomaga faigata.
Le faʻatuatuaina maualuga ma le faʻalavelave faʻalavelave
Fa'apena le fa'alavelave fa'aleleia o meafaigaluega:
Faʻaaogaina le faʻatulagaina o le PCB faʻapipiʻi tele, talipupuni electromagnetic (e pei o le ufiufi uʻamea uʻamea), faʻamama le mana (LC filtering circuit, motumotu mana module) ma faʻailoga faʻapitoa tekonolosi (optocoupler vavae ese, faʻasalalau faʻailoga eseese), e matua tetee atu i le faʻalavelave eletise (EMI), faʻalavelave leitio (RFI) ma le pisa malosi i totonu o nofoaga faʻapisinisi, faʻafefe ai le pisapisao malosi i nofoaga faʻapisinisi, faʻafefe ai le pisapisao malosi i nofoaga faʻapisinisi, faʻafefe ai le pisapisao malosi i nofoaga faʻapisinisi, faʻafefe ai le pisa malosi i totonu o nofoaga faʻapisinisi, faʻafefeina le pisapisao malosi i nofoaga faʻapisinisi, faʻalavelave faʻalavelave. taavale afi.
Tele vevela ma lautele mamafa fetuutuunai:
Filifili vaega fa'aeletoroni vasega alamanuia (e pei o le vevela ambient: -30 ° C i + 65C; susū fa'atatau: 5% i 95%; Atmospheric mamafa: 86KPa ~ 106KPa, lautele voltage input module), lagolago DC 12 ~ 24V po o le AC 220V malosiaga tuuina, talafeagai mo siosiomaga faigata e pei o fafo, vibration eseese.
O le laupapa matagaluega a levortex flowmetermaua le sa'o, mautu, ma le fetuutuuna'i i le fua o le tafe e ala i mea lelei e pei o le faʻaogaina o faailoilo maualuga, malosi malosi e tetee atu i le faʻalavelave, faʻaogaina faʻaogaina atamai, ma le mamanu maualalo. E faʻaaogaina lautele i pisinisi e pei o petrochemicals, malosiaga, vai, metallurgy, ma isi, aemaise lava i tulaga faigata o galuega ma faiga faʻaautomatika. O lona taua autu o loʻo taoto i le galulue faʻatasi o polokalama ma meafaigaluega e faʻaleleia ai le faʻatinoga o meafaigaluega aʻo faʻaitiitia le faʻaogaina ma le tausiga o tau.
