Yakasiyana-siyana yekuyerera mita inoshanda mukusimudzira mashandiro ehurongwa, huchokwadi uye kunyangwe kuvimbika kunogara kwenguva refu. Izvo zvakakosha kuti utarise mune nuances ega ega rudzi uye magadzirisiro avari kuita zvakakosha maindasitiri. Tsvaga rudzi rwemamita ekuyerera kuti uenderane nezvinodiwa chaizvo.
Mhando dzeFlow Meters
Misa yekuyerera mita
Amisa yekuyerera mita, inonzi inertial flow meter, inoshandiswa kuyera kuyerera kwehuwandu hwemvura inoyerera nemuchubhu. Huremu hwemvura inoyerera ichipfuura nzvimbo yakatarwa pachikamu chenguva inodaidzwa kuti mass flow rate. Meta inoyerera inoyera huremu kwete vhoriyamu pachikamu chenguva (eg makgs pasekondi) kutumira nemumudziyo.
Coriolis inoyerera mamitaanotorwa seakanyanya kuyerera mamita anodzokororwa parizvino. Vanotumira mvura mumachubhu anozunguza uye vanoongorora shanduko mukufamba kwemvura. Fluids kuburikidza nemachubhu anozunguzika anokonzera kumonyoroka zvishomanana kana kuremara. Kumonyoroka kwakadaro nekuremara kwakanyatso kuenzana nekuyerera kwehuwandu. Coriolis metres anoita mune ese ari mavirimisa uye density kuyerwa, kuve nekuchinjika mukushandisa kwakasiyana semakemikari, oiri, uye gasi maindasitiri. Kuita kwavo kwakatanhamara mukurongeka uye kushandiswa kwakapararira zvikonzero zvekutanga zvekuzivikanwa kwavo mumaindasitiri akaomarara masisitimu.
Chidziviso Type
Differential Pressure (DP) inoyerera mitadzakagadziridzwa kushanduka mune zvemazuva ano indasitiri zvinodiwa, ichisara ndiyo yakavimbika sarudzo mukuyerera kwekutarisa uye kuyerwa. Musiyano wekumanikidza unoyerwa pahwaro hwemusimboti wekuti humwe hukama pakati pemusiyano wekumanikidza unogadzirwa kana mvura ichiyerera kuburikidza nemidziyo yekupuruzira uye kuyerera kwemazinga. Iyo throttling mudziyo inzvimbo inomisikidza chinhu chakaiswa mupombi. Anonyanya kushandiswa ndiwoorifice plates, nozzlesuyeventuri tubes,iri kushandiswa zvakanyanya mumaindasitiri maitiro kuyerwa uye kutonga.
A variable area mitainoshanda kuburikidza nekuyera kuyerera kwemvura ichiyambuka nzvimbo yechikamu chemudziyo kuti isiyane mukupindura kuyerera. Imwe miyero inoyerwa inoratidza mwero. A rotameter, muenzaniso wemamita enzvimbo yakasiyana, inowanikwa kune zvakasiyana-siyana zvezvinwiwa uye inowanzoshandiswa nemvura kana mhepo. Mumwe muenzaniso inzvimbo yakasiyana-siyana yenzvimbo, umo mvura inoyerera ichitumira nepakati pemvura inotsvedza chitubu chakaremerwa tapered plunger.
Inferential Flowmeter
Theturbine flowmeterinoshandura chiitiko chemuchina kusvika kuchiyero chinoverengeka chekuyerera. se gpm, lpm, etc. Gumbo returbine rakaiswa munzira yemvura inoyerera kuitira kuti kuyerera kwese kunofamba kuritenderedza. Ipapo mvura inoyerera inopindira pamashizha eturbine, ichibudisa simba pabeche uye kusundira rotor mukufamba. Sipidhi yeturbine inoenzanirana nekumhanya kwemvura kana kutenderera kwakadzikama kwasvika.
Electromagnetic Flowmeter
Themagnetic flowmeter, inozivikanwawo se "mag meter"kana"electromag", shandisa megnetic munda wakaiswa kune metering chubhu, iyo inokonzera mutsauko unogona kuitika mukuyerera kwevelocity perpendicular kune flux mitsara. Mamita akadaro anoshanda paFaraday's Law of Electromagnetic Induction, umo magineti anoshandiswa kune mvura. Zvadaro chiyero chekuyerera chinogona kutariswa neyakayerwa inokonzeresa voltage kunyatsojeka uye kusimba,magnetic flow mamitainowanzoshandiswa mukurapa kwemvura, kushandiswa kwemakemikari, pamwe chete nekugadzirwa kwezvokudya uye zvinwiwa.
Anultrasonic kuyerera mitainoyera velocity yemvura ne ultrasound kuverenga kuyerera kwevhoriyamu. Iyo yekuyerera mita inokwanisa kuyera avhareji velocity munzira yeyakabudiswa danda re ultrasound kuburikidza ne ultrasonic transduces. Verenga mutsauko wenguva yekufambisa pakati pemapulses eultrasound pasi kupinda kana kupokana negwara rekuyerera kana kuyera frequency shift uchivimba neDoppler Effect. Pamusoro peiyo acoustic midziyo yemvura, tembiricha, density, viscosity uye yakamiswa zvidimbu zvakare zvinhu zvinokanganisaUltra flow mita.
Avortex kuyerera mitainoshanda pamusimboti "von Kármán vortex", inotarisa mwero wekuyerera kwemvura nekuyera kuwanda kwemavortices. Kazhinji, kuwanda kwemavortices kwakanyatso kuenzana nehuwandu hwekuyerera. Iyo piezoelectric element mu detector inogadzira inochinjanisa yekuchaja chiratidzo chine frequency yakafanana neye vortex. Ipapo chiratidzo chakadaro chinounzwa kune yakangwara kuyerera totalizer kuti iwedzere kugadzirisa.
Mechanical flowmeters
A positive displacement mita inoyera huwandu hwemvura inoyerera nemudziyo sebucket kana stopwatch. Chiyero chekuyerera chinogona kuverengerwa nereshiyo yehuwandu uye nguva. Kuzadza nekudurura mabhaketi nguva dzose kunodiwa nechinangwa chekuyera kuenderera. Piston metres, oval giya metres uye nuating disk mita yese mienzaniso yemamita akanaka ekutamisa.
Kubva kune akasiyana-siyana mechanicha inoyerera kusvika kune chaiyo Coriolis uye ultrasonic metres, mhando yega yega yakagadzirirwa kusangana nezvinodiwa zvemaindasitiri. Kunyangwe iwe uchida kubata magasi, zvinwiwa, kana chiutsi, pane mhinduro yako. Tora danho rinotevera rekuvandudza mashandiro ehurongwa hwako nekusvika kune hutungamiriri hwenyanzvi.Taura nesunhasi kune yemahara, isina-chisungo quote, uye rega tikubatsire iwe kuwana yakakwana yekuyerera mita yekushanda kwako!
