Mumabasa emaindasitiri kubva pakugadzira mishonga kusvika pakugadzirisa mvura yakasviba, kuyerwa kwemvura kunosangana nematambudziko asingaperi. Maacid anoora, slurry dzakasimba, uye slurry dzakasimba dzine zvimedu zvakasimba zvakaedza kwenguva yakareba miganhu ye flow metres yechinyakare, zvichikonzera kuputsika kakawanda, kuverenga kusina kururama, uye nguva inodhura yekuzorora. Zvichienderana neizvi, electromagnetic flow metres (EMFs) dzakabuda semhinduro yakasimba, yakagadzirirwa kukunda mamiriro emvura akaomarara. Kusiyana nema mechanical metres anokundwa nekusakara, kuvharika, kana kurwiswa nemakemikari, EMFs dzinobudirira apo dzimwe dzinokundikana—zvichiratidza kuti hapana fluid yakaoma kuyera nekururama uye kuvimbika.
Matekinoroji ekuyera kuyerera kwechinyakare anonetsa kufambirana nemvura dzinodiwa. Semuenzaniso, ma turbine metres anovimba nema curves anotenderera anopwanyika nyore nyore nezvidimbu zvinokwenya kana kuputirwa nemvura dzakasimba dzakadai se molasses kana sludge. Ma Orifice plates nemaVenturi tubes anowanzo vharika pakubata slurry, nepo zvikamu zvavo zvesimbi zvichikurumidza ngura kana zvasangana nemakemikari akadai se hydrochloric acid kana sodium hydroxide. Izvi zvinoshandura kurongeka kwakashata: mita yakavharika kana yakasakara inogona kutsauka ne10% kana kupfuura kubva pahuwandu hwechokwadi hwekuyerera, zvichikonzera dosing isiriyo mumaitiro emakemikari, overbilling mukutakura kwemvura, kana kusatevedzera mitemo yezvakatipoteredza. Kune maindasitiri ane hunhu hwemvura hunoshanduka-shanduka—senge kugadzira chikafu, uko viscosity inochinja nekupisa—ma current metres haapi mukana wekuchinja, zvinoda kugadziriswazve kana kutsiviwa.
Ma electromagnetic flow meter anokunda matambudziko aya kuburikidza nedhizaini yakasiyana zvachose: anoyera kuyerera pasina kusangana zvakananga nezvikamu zvinofamba, achishandisa Mutemo waFaraday weElectromagnetic Induction. Heino mashandiro azvinoita: pombi yemita yakafukidzwa nezvinhu zvinodzivirira makemikari (senge PTFE, rabha, kana ceramic), nepo ma electrode maviri akaiswa mukati me lining achigadzira simba remagineti pamusoro pemvura. Sezvo conductive fluid ichiyerera mumunda, inokonzera voltage yemagetsi inoenderana nekumhanya kwayo - voltage iyi inoyerwa nema electrodes uye inoshandurwa kuita data re flow rate. Kusavapo kwezvikamu zvinofamba kunobvisa kupera kubva ku abrasives uye kuvharika kubva ku viscous fluids, nepo non-metal lining inoshanda sechipingamupinyi kubva kune zvinoparadza. Dhizaini iyi inoita kuti ma EMF arambe akasimba uye akarurama kunyangwe pakubata mvura inoparadza mita dzechinyakare.
Chinoita kuti maEMF akwanise kuchinja-chinja inyaya yekugona kwawo kugadzirisa hunhu hwemvura yakawandisa. Kune mvura inoparadza—kubva kumaindasitiri acids nema alkalis kusvika kumvura yegungwa uye makemikari anonyungudutsa—midziyo yemita inogona kugadziriswa kuti ienderane nekushandiswa kwayo. PTFE linings dzinodzivisa makemikari akawanda e organic uye inorganic, zvichiita kuti dzive dzakakodzera mishonga kana petrochemical processes, nepo rabha linings dzichigona kubata abrasive slurry dzine zvidimbu zvikuru, zvakaita sekuchera tailings kana mvura yakasviba ine sediment. Viscous fluids, kusanganisira adhesives, lubricants, uye chikafu chakadai sechokoreti kana syrup, zvinoyerera zvakanaka kuburikidza nepaipi isina kuvharwa yeEMF, pasina nzira dzakamanikana dzinokonzera kuungana. Kunyangwe abrasive fluids dzine jecha, matombo, kana simbi shavings dzinopfuura pasina kukuvadza mita, sezvo pasina zvinhu zvinotenderera zvekupera. Kuchinjika uku kunoreva kuti EMF imwe chete inogona kubata mhando dzakasiyana dzemvura mumatanho akasiyana ekuita, zvichideredza kudiwa kwemamita akasarudzika.
Kupfuura kugara kwenguva refu, maEMF anopa kunyatsojeka kunokosha mukushandiswa kwakakosha. Anochengetedza kururama mukati me ±0.5% yehuwandu hwakazara (uye kazhinji zviri nani) munzvimbo yakakura yekuyerera, kubva pakumhanya kwakaderera (kwakaderera se 0.01 m/s) kusvika pakuyerera kwakakwirira kwakakodzera mapaipi emaindasitiri. Kunyatsojeka uku kwakakosha pakugadzirisa makemikari, uko kuyera kwakarurama kwezvinhu zvakagadzirwa kunovimbisa kunaka kwechigadzirwa uye kuchengetedzeka, uye pakurapa mvura yakasviba, uko ruzivo rwekuyerera kwakarurama runotsigira kutevedzera miganhu yekuburitsa. MaEMF anobudirirawo pakuyera mvura isina kufanana, senge slurry ine huwandu hwakasiyana hwakasimba, iyo inovhiringidza mita dzechinyakare. Kugona kwavo kupa data rakafanana uye rakavimbika kunyangwe mumamiriro emvura asina kugadzikana kunoita kuti vasave vakakosha kumaindasitiri uko kudzora maitiro kwakakosha zvikuru.
Mabhenefiti anoshanda eEMF anowedzera pakushanda zvakanaka uye kuchengetedza mari. Pasina zvikamu zvinofamba zvekugadzirisa kana kutsiva, zvinoda kugadziriswa kushoma—kazhinji kungoongororwa nguva nenguva makore ese 1-3, zvichienzaniswa nekuchengetedzwa kwemechanical metres kota yega yega. Izvi zvinoderedza nguva yekushanda uye mari yekugadzirisa, kunyanya munzvimbo dzakaoma kusvika senge mapaipi epasi pevhu kana nzvimbo dzemaindasitiri dzinopisa zvakanyanya. MaEMF ari nyorewo kuisa, ane sarudzo dze flange, wafer, kana insertion mounting dzinoenderana nemapaipi aripo pasina shanduko huru. Mazhinji maEMF emazuva ano anobatanidza IoT connectivity, zvichibvumira kutarisa nguva chaiyo yekufamba kwemvura, nyevero dzekuongorora kwekupfeka kwe lining kana electrode fouling, uye remote calibration. Unyanzvi uhwu hwedhijitari hunogonesa kugadzirisa nekukurumidza, kudzivirira kutadza kusingatarisirwi uye kuona kuti kushanda kunoramba kuripo.
Kubva pakuchera, mafuta negesi kusvika pakugadzira chikafu nemishonga, maEMF ave sarudzo huru kumaindasitiri ari kurwisana nemvura dzakaoma. Mumafekitori emakemikari, vanoyera ma reagents anoparadza nekunyatsojeka, vachiona kuti zvinoitwa sei zvakachengeteka uye zvinobudirira. Munzvimbo dzekuchenesa mvura yakasviba, vanobata tsvina inokuvadza uye mishonga yekuchenesa, vachipa ruzivo rwekugadzirisa maitiro ekurapa. Muindasitiri yezvikafu nezvinwiwa, vanoyera zvigadzirwa zvakakora zvakaita sehuchi kana tomato paste pasina kusvibisa mvura yacho kana kukanganisa kuravira kwayo. Kunyangwe munzvimbo dzakaoma—senge mapaipi ane simba rakawanda kana mashandisirwo e cryogenic—maEMF anopa kushanda kwakasimba, zvichiratidza kuti anoshanda zvakasiyana-siyana muzvikamu zvakasiyana.
Sezvo maitiro emaindasitiri achikura akaomarara uye matambudziko emvura achikura zvakanyanya, kudiwa kwekuyera kuyerera kwakavimbika uye kunochinjika kunongowedzera. Mamita ekuyerera emagetsi anoonekwa semhinduro isingangoyere mvura chete—inoikunda. Nekubata mvura inoparadza, yakakora, uye inokwesha zviri nyore, vanobvisa kutengeserana pakati pekugara kwenguva refu uye kururama kunotambudza mamita echinyakare. Kune mabhizinesi, izvi zvinoreva kudzikiswa kwemitengo, kuvandudzwa kwekudzora maitiro, uye rugare rwepfungwa vachiziva kuti kuyerwa kwavo kwekuyerera kunoenderana nechero dambudziko.
Munyika umo mvura dziri ropa rehupenyu hweindasitiri, ma electromagnetic flow meter ndiwo magamba asingazivikanwe anoramba achishanda zvakanaka. Anoratidza kuti kunyangwe mvura yacho yakaoma sei, kuyera kwakarurama hakusi kungogoneka chete - kunoshanda. Sezvo tekinoroji ichifambira mberi, maEMF acharamba achichinja, achipa kusimba kwakanyanya uye hungwaru. Asi parizvino, anoramba ari iwo mwero wepamusoro wekubata mvura inonyanya kudiwa, achitsanangura patsva zvinogoneka mukuyera kuyerera kweindasitiri.
