Ma electromagnetic flow metres (EMFs), zvichibva paMutemo waFaraday we electromagnetic induction, akaonekwa sezvishandiso zvakakosha pakuyera mvura munzvimbo dzakasiyana siyana. Kusiyana nema mechanical flow metres ane zvikamu zvinofamba, ma EMF anoshanda nekuona simba re electromotive rinokonzerwa kana mvura inoyerera ichiyerera mumunda wemagineti, zvichipa zvakanakira zvakaita sekururama kwakanyanya, kurasikirwa kushoma kwekumanikidzwa, uye kuramba tsvina yemvura. Kugona kwavo kushanda nesimba uye kuvimbika kwakaita kuti vave sarudzo inofarirwa mukushandiswa kubva pakutarisira mvura yemumaguta kusvika kumaindasitiri epamusoro.
Muchikamu chemvura nemarara chemaguta, maEMF anoita basa rakakosha mukuona kuti zviwanikwa zvinofambiswa zvakanaka. Pakuwanikwa kwemvura inonwiwa, vanoyera kufamba kwemvura nemazvo muma network ekugovera, zvichiita kuti makambani akwanise kutarisa maitiro ekushandiswa kwemvura, kuona kubuda kwemvura, uye kugadzirisa kudzora kumanikidzwa kwemvura. Izvi hazvingoderedzi chete kutambisa mvura asi zvinovimbisawo kubhadhariswa kwakakodzera kwevashandisi vedzimba nevemabhizinesi. Munzvimbo dzekuchenesa mvura, maEMF anotsungirira mamiriro akaoma etsvina isina kucheneswa uye tsvina yakarapwa, zvichipa zviyero zvakanyatsonaka zvekudzora maitiro—sekudzora chiyero chemakemikari ekudzivirira kuvharika uye kuuraya utachiona. Kugona kwavo kubata mvura ine zvinhu zvakanyungudika nezvinhu zvinoparadza kunoita kuti ive yakanaka pakutarisa kupinda nekubuda kwemvura, kuona kuti mitemo yezvakatipoteredza inotevedzera.
Chikamu chemaindasitiri chinoshandisa maEMF pakuita mabasa akasiyana-siyana ekutarisa nekugadzirisa maitiro. Muindasitiri yemakemikari, uko kuyera mvura kwakakosha pamhando yepamusoro uye kuchengetedzeka kwechigadzirwa, maEMF anoyera kufamba kwe corrosive acids, alkalis, uye viscous polymers. Magadzirirwo avo asingapindi anobvisa njodzi yekusvibiswa uye anoderedza kugadziriswa, sezvo pasina zvikamu zvemukati zvinofamba zvekupfeka kana kuvharika. Muindasitiri yezvikafu nezvinwiwa, maEMF emhando yehutsanana (akavakwa nesimbi isingatsvedzeri uye anosangana ne3A kana EHEDG standards) anotarisisa kufamba kwemafuta anodyiwa, zvigadzirwa zvemukaka, uye muto wemichero. Anovimbisa kusanganiswa kwakarurama kwezvinhu, anodzivirira kuzadza zvakanyanya, uye anotsigira kuteverwa mumitsetse yekugadzira, achitevedzera zvinodiwa nehutsanana uye zvemhando.
Chikamu chekugadzira simba nemagetsi chinovimbawo zvakanyanya neEMFs. Muzviteshi zvemagetsi zvinopisa, vanoyera kuyerera kwemvura inotonhorera, mvura inofashaira muboiler, uye mafuta emafuta, zvichibatsira kugadzirisa kushanda zvakanaka kwesimba uye kudzivirira kupisa kwemidziyo. Kune zvivakwa zvemagetsi zvinoshandisa mvura, maEMF anotarisa kuyerera kwemvura mumaturbines, achipa data rekugadzirisa kubuda kwesimba uye kuona kuti kushanda kwaro kwakasimba. Pamusoro pezvo, mumapurojekiti esimba rinogona kudzokororwa sezviteshi zvebiogas, maEMF anoteedzera kuyerera kwebiogas (mvura inofambisa mvura kana yakasanganiswa nehunyoro) panguva yekugadzira nekugovera, zvichitsigira kushandurwa nekuchengetwa kwesimba zvakanaka.
Muindasitiri yemigodhi nesimbi, maEMF anotarisana nedambudziko rekuyera mvura inokwesha uye ine simba rakawanda. Anotarisa kufamba kwetsvina (musanganiswa wemvura nezvicherwa) mumafekitori ekugadzira simbi, achivimbisa kuti huwandu hwekudya hunoenderana kune macrusher nemaseparator. Kugadzirwa kwavo kwakasimba—nemarabha akasimbiswa akagadzirwa nerabha kana polyurethane—kunodzivirira kupera kwesimbi inokwesha, zvichideredza nguva yekushanda uye mari yekugadzirisa. Munzvimbo dzesimbi dzinokwesha, maEMF anodzora kufamba kwemhinduro dzemagetsi, achivimbisa ukobvu hwakafanana hwekukwesha uye achideredza marara ezvinhu.
Kutarisa zvakatipoteredza uye kutarisira zviwanikwa zvemvura ndeimwe nzvimbo inokosha inoshandiswa. MaEMF anoshandiswa munzvimbo dzekutarisa nzizi nepasi pevhu kuyera mwero wekuyerera kwemvura, kutsigira kufanotaura kwemafashamo uye kugoverwa kwezviwanikwa zvemvura. Anotarisawo kuburitswa kwetsvina mumaindasitiri mumvura yechisikigo, achivimbisa kutevedzera mitemo yekudzora kusvibiswa. Munzira dzekudiridza dzekurima, maEMF anovandudza mashandisirwo emvura nekuyera kuyerera kwemvura kuminda, kukurudzira nzira dzekurima dzinogara kwenguva refu uye kuchengetedza zviwanikwa zvemvura zvishoma.
Kunze kwezvikamu izvi, maEMF anowana mashandisirwo akakosha muindasitiri yemishonga (kutarisa kuyerera kwemhinduro dzakachena uye maAPI), indasitiri yepulp nepepa (kuyera pulp suspensions uye zvinowedzera zvemakemikari), uye kunyangwe mumabasa emugungwa nekunze kwenyika (kutevera kuyerera kwemvura ye ballast kudzivirira kupararira kwemarudzi anopararira).
Mukupedzisa, ma electromagnetic flow meter ave musimboti wekuyera mvura yemazuva ano, nekuda kwekurongeka kwayo, kushanduka-shanduka, uye kugara kwenguva refu. Kugona kwayo kubata mvura dzakasiyana-siyana—kubva mumvura yakachena kusvika kumakemikari anoparadza uye slurry inokuvadza—zvinoita kuti ive yakakosha muzvikamu zvemaguta, maindasitiri, simba, uye zvakatipoteredza. Sezvo maindasitiri achiramba achikoshesa kushanda zvakanaka, kugara kwenguva refu, uye kutevedzera mitemo, kudiwa kweEMFs kuri kukura, zvichikonzera kuvandudzwa kwakawanda mukugadzira kwavo uye mashandiro avo kuti vasangane nezvinodiwa zvekushandisa zviri kuchinja.
