Folasaga

Tia Eseese-omiomi flowmeter ua faia i luga o le masini throttling, transmitter eseese ma tafe accumulator.TO le masini faʻapipiʻi o se elemene autu faʻapipiʻiina i luga o le paipa, e masani ona faʻaaogaina i le fuaina o le tafe o ituaiga uma o kesi.(lea e mama pe o iai le pefu), ausa(lea ua tumu pevevela tele) ma vai (lea e ta'ita'i pe leai, e malosi le pala, pipii, pala pe i ai ni vaega, ma isi..), ma e mafai ona fua sa'o le tafe o le voluma po'o le lelei.

Fa'atatauga

Ole mita tafe ole fa'asologa fa'alava fa'aau e iai ta'iala ole fa'agaioiga o le mamafa ma auala fa'apipi'i. E mafai ona fa'aogaina mo le fuaina o le tafe o kesi, vai, ma ausa. E masani ona fa'aoga fua fa'aauvai mita e aofia ai Verabar flowmeters, Deltabar flowmeters, ma Aniu flowmeters. Bar flowmeters, flowmeters uma o lenei ituaiga e faʻavae i luga o le pitot tube principle. Ina ua mae'a fa'atonuga fa'atulagaina, ua latou fa'atupuina i nei ituaiga o mita tafe. O latou fausaga e tutusa lava ma e iai uma foliga nei: fausaga faigofie, faʻaitiitia le mamafa o le mamafa, faigofie faʻapipiʻi ma tausiga Faʻatasi ai ma faʻamanuiaga mataʻina e pei o le faʻaogaina ma le tele o le faʻaolaina o le malosi, o se fua faʻatatau maualuga e mafai ona faʻaogaina i lalo o le malosi. tulaga faigaluega ma tausia lelei le faatinoga o fua.

Tulaga lelei

Tia Throttling masini o le uluai faiga faʻaaogaina o le fua o le tafe ma le talafaasolopito sili ona umi, ma o le auala sili ona faʻaaogaina i le taimi nei. O ona fa'amanuiaga autu e fa'apea:

Mo Tulaga Fa'amauMeafaigaluega, e leai se manaʻoga e faʻavasega le tafe moni e fuafua ai lona fuasa'o (ma ua na o le pau lea o le meafaigaluega tafe i le taimi nei).
Te matua tele lava le fa'aogaina o ala fa'atatau o le masini fa'ato'a.Te toetoe lava a fa'aoga i le fuaina o le tafeo kasa uma, ausa ma vai.
Ole tele olepaipao le caliber e matua lautele foi, lea e mai Φ 2~Φ3000 mm pe ua umaΦ3000. Tfa'aau fa'alava fa'alava foliga lapotopoto pe fa'afa'afa'afa e lelei uma.
O lona mamafa galue e mafai ona oʻo atu i le 32 MPa ma e mafai foi ona faʻaoga i lesuatmospheric omiga.
Temperature laina o alalaupapa: -185^oC ~ + 650^oC (lea e le mafai mo isi mita tafe.
E tele ituaiga o fausaga o le Fa'asa'o Fa'atonuMeafaigaluega, lea e toetoe lava a faʻaaogaina i le fuaina o le tafeo mea uma ituaiga vai.
O lelauteleo le tafe e mafai ona suia i le nofoaga e ala i le setiina o leagao le transmitter Differential-pressure.
Its fa'agaioiga ma fa'aoga e matua faigofie lava ma e mafai ona pulea faigofie. E le gata i lea, o lona tausiga i aso uma e matua tele lavaitiiti.

Faiaoga galue

O legaluetalitonuga o le fua o le tafe o o le masini fa'amalo faavae i luga o le lauiloa Bernoulli Hydrodynamic Theory. As o loʻo faʻaalia i le ata o loʻo i lalo (1), afai e tuʻuina se tasi elemene faʻapipiʻi i totonu o le paipa, o le a faʻapipiʻiina se 'eseʻese-omiga (Differential-pressure P) i itu uma e lua o le elemene faʻamalosi pe a iai ni vai e tafe atu i totonu o le elemene faʻafefe, ma o le tafe i le taimi lea e tutusa ma le aʻa sikuea o le mamafa o le eseesega, lea'e fai atu,
Volume tafe: Q_V= A *C /√ (1-β⁴)* ε * o²* √ (ΔP/ρ )
In le fua,
A----e faasino i mea faifai pea;
C---e faasino i le fa'aputuga o le suavai;
β---e faasino i le fua o le lautele (=D/d);
d---e faasino i le pu calibero le elemene fa'alaiti (mm);
ε---e faasino i le aofa'i fa'atele;
ΔP --- e faasino i le Eseese-omiga i le va o luma ma tua o le elemene throttling (Pa);
ρ---refers i le mamafa o le sua i le tulaga galue (Kg/m³).
