Chiyero chemvura inoyerera (vortex flowmeter) chishandiso chekuyera kuyerera kwemvura chakagadzirwa zvichibva pane "Kármán vortex street". Kana mvura ichiyerera ichipfuura nepaburi remvura (vortex shedder) mukati mepombi, mitsara yemhepo inoshanduka inogadzirwa kumativi ese. Nekuona frequency yemhepo nesensor uye kuisanganisa neparameters dzakadai sedhayamita yepombi uye density yemvura, kumhanya kwemvura uye mwero wekuyerera kwemvura zvinogona kuverengerwa nemazvo.
Sechishandiso chekuyera chinodhura zvishoma, chinoita kuti zvive nyore uye kuti zvishande zvakanyanya, ma "vortex flow metres" anoshandiswa zvakanyanya muindasitiri mukuita otomatiki zvinhu zvakaita sema "petrochemicals", simba, uye kurapwa kwemvura. Zvisinei, chiyero che "vortex flowmeter" ndicho chinopa kunyatsorongeka kwakanyanya uye chinoshanda zvakanyanya.chiyero chekuyerera kwevolumetric chiri mumamiriro ekushanda(tembiricha yekushanda nekumanikidzwa). Kukosha uku kunogona kusasangana zvakananga nezvinodiwa zvekudzora maitiro mumabasa mazhinji anoshanda:
Kuyerwa kweGasi neUtsi:Kune mvura dzinomanikidzwa—gasi nemhepo—huwandu hwevanhu hunokanganiswa zvikuru nekuchinja kwetembiricha nekumanikidzwa. Kuwedzera kwekumanikidzwa kana kudzikira kwetembiricha kunotungamira mukuwedzera kukuru kwehuwandu hwevanhu, uko kutsauka kukuru kunogona kuunzwa nekuda kwekuchinja kwehuwandu chaihwo hwenzvimbo yacho. Semuenzaniso, mwero wakafanana wekuyerera kwegasi rechisikigo pasi pemamiriro ekumanikidzwa kwakanyanya unoenderana nehuremu hwakakura kupfuura pasi pesimba rekumanikidzwa kwakaderera.
Mamiriro Akakosha Mukuyera Mvura:Kunyangwe zvinwiwa zvinowanzoonekwa sezvisingapindiki, huwandu hwazvo hunoramba huchiwedzerwa kana kumanikidzwa nekupisa kwakanyanya kana kumanikidzwa. Kune zvinwiwa zvinopisa zvakanyanya uye zvinomanikidzwa zvakanyanya (tembiricha > 100°C kana kumanikidzwa > 10 MPa), zvinwiwa zvinoputika (senge methanol, ethanol), kana mashandisirwo anoda kunyatsorongeka kwakadai sezvinhu zvakakosha zvekudzora maitiro, kuregeredza kugadziriswa kwemhedzisiro yetembiricha nekumanikidzwa pahuwandu hwemvura kuchaitawo kuti pave nezvikanganiso zvakakura.
Kuti dambudziko iri rigadziriswe, muripo wekupisa nekumanikidzwa kwemuchina wekuongorora mvura (vortex flowmeter) unodiwa. Nekuyera tembiricha nekumanikidzwa kwemvura panguva chaiyo uye nekubatanidza hunhu hwemvura, mwero wekuyerera kwemvura (volumetric flow rate) unoyerwa nemuchina wekuongorora mvura (vortex flow meter) unogona kushandurwa nemazvo kuita zvinodiwa.mwero wekuyerera kwehuwandu or mwero wekuyerera kwehuwandu hwevhoriyamu.
Nzira yechinyakare yekuripa mari inosanganisira kugadzirira vortex flowmeter ne sensor yekuwedzera tembiricha yakazvimirira (semuenzaniso, thermometer yekudzivirira platinum) uye transmitter yepressure. Zviratidzo zvitatu zvinozoiswa mu flow totalizer kana system yekudzora kuti zviverengerwe. Dhizaini iyi inowanzo wedzera kuoma kwekuisa uye mutengo. Nekuda kweizvozvo, tekinoroji yekubatanidza tembiricha nekuripa simba yave kubuda senzira yekuvandudza. Inobatanidza zvinhu zvekunzwa tembiricha nekuripa simba zvakanyatsonaka ne sensor yekuyerera kwevortex muyuniti imwe chete, yakamanikana yekuyera. Zvakanakira zvayo zvikuru zvinosanganisira:
Kuvandudza Kurerutsa Sisitimu uye Kuvimbika:Inoderedza waya dzekunze uye huwandu hwezvishandiso zvakazvimiririra, inoderedza mari yekuisa nekugadzirisa uye inovandudza kusapindirana kwehurongwa uye kugadzikana kwenguva refu.
Kubatanidza Data uye Kuvimbisa Kururama:Masensa akavakirwa mukati anoyera zvakananga tembiricha chaiyo nekumanikidzwa kwemvura iri pedyo nevortex shedder, zvichigonesa kuwanikwa kwema parameter akawanda pamwero wakafanana uye kudzivirira zvikanganiso zvekubhadhara zvinokonzerwa nekusawirirana kwemapoinzi ekuyera.
Kubatanidzwa Kwebasa uye Ungwaru:Module yekuverenga yakabatanidzwa inogona kushandisa tembiricha yakawanikwa uye pressure values pamwe chete nemamodheru epakati-kati (akadai segas equation of state, steam tables, kana liquid correction formulas) kuti iite online real-time calculation uye output standard volumetric flow rate kana mass flow rate, zvichiita kuti system isanganisirwe zvakananga uye zviri nyore.
Kubhadharwa kwekupisa nekumanikidzwa kwakabatana kunomiririra kuvandudzwa kwakakosha kwemamita ekuyerera kwemhepo kuti agadzirise shanduko muhunhu hwemvura nemamiriro ekushanda uye kuwana shanduko yekuyerera kwakanyatsojeka, zvichitsigira zvinodikanwa zvekudzora maitiro chaiwo.Shanghai Wangyuanane ruzivo rwemakore anopfuura makumi maviri mubasa rekugadzira nekupa zviridzwa, achipa ruzivo rwakasiyana-siyanazvigadzirwa zvekuyera kuyereraKana muine zvinodiwa maererano nema "vortex flowmeters", tinofara kukupai mhinduro. Ndapota inzwai makasununguka kutibata chero nguva.
