Mukutarisira mvura mumaindasitiri, kururama uye kushanda zvakanaka hazvigone kukurukurwa—asi ndizvo zvakaitawo kudzora mutengo kwenguva refu. Pamabasa akasiyana-siyana kubva kumafekitori ekuchenesa mvura kusvika kumafekitori ekugadzira makemikari, kutsvaga maturusi ekuyera anoenzanisa kunyatsorongeka nekuchengetedza kushoma kwakaita kuti vazhinji vawane mhinduro inochinja-chinja: low-maintenance electromagnetic flow meters (EMFs). Kusiyana nemamechanical flow metres echinyakare anovimba nezvikamu zvinofamba zvinogona kupfeka, kuvharika, kana ngura, zvishandiso izvi zvepamusoro zvinoshandisa Faraday's Law of electromagnetic induction kupa data rakavimbika—zvose izvi zvichideredza nguva yekugadzirisa, mari yevashandi, uye nguva isina kurongwa yekushanda. Munyika yemazuva ano yeindasitiri inokurumidza, maEMF asina kugadziriswa zvakanyanya haasi kungobatsira chete; iwo mari yekudyara mukubudirira kwekushanda.
Chinhu chikuru pakukosha kweEMFs dzisingagadzirise zvakanyanya ndiko kugadzirwa kwadzo kusingapindi, kusina chikamu. Ma flow meter echinyakare, akadai se turbine kana positive displacement models, anoshandisa zvikamu zvinotenderera kana zvipingamupinyi zvemuviri kuyera kuyerera kwemvura. Nekufamba kwenguva, zvikamu izvi zvinoora nekuda kwekukweshana, kusangana nemvura inokwesha kana inoparadza (semuenzaniso, mvura yakasviba ine sediments, chemical slurry), kana kuunganidzwa kwezvinosvibisa zvakaita se scale kana sludge. Kuora uku kunomanikidza kuongororwa kakawanda, kutsiva zvikamu, uye calibration—maitiro anodhura anowanzo da kudzima system yese. Ma EMF asingagadzirise zvakanyanya, nekusiyana, haana zvikamu zvinofamba. Pane kudaro, ane sensor tube ine zvinhu zvinodzivirira ngura (semuenzaniso, PTFE, rabha) uye maviri electromagnetic coils. Kana fluid inopfuura nepachubhu, coils dzinogadzira magnetic field, uye ma electrodes anoona voltage inokonzerwa nekufamba kwemvura—achiverenga zvakananga flow rate pasina kubata kwemuviri. Dhizaini iyi inobvisa njodzi yekukundikana kwezvikamu, kuvharika, kana kupfeka kwemuchina, zvichideredza zvakanyanya kudiwa kwekugadzirisa nguva dzose. Semuenzaniso, kune nzvimbo yekuchenesa mvura yekanzuru, izvi zvinoreva kudzivirira kuvharwa kwemwedzi wega wega kuti uchenese mita dzemagetsi; pachinzvimbo, EMF inoshanda nguva dzose, ichingodiwa chete kuongororwa kwekuongorora kwegore negore.
Kupfuura kuderedza basa rekugadzirisa, maEMF asingagadzirisike zvakanyanya anotungamira mukushanda zvakanaka kwemari kuburikidza nekugara kwenguva refu uye kushanduka-shanduka. Kuvaka kwavo kwakasimba—kusanganisira dzimba dzesimbi dzisingatsvi nesimbi dzinodzivirira makemikari—kunoita kuti vagone kutsungirira mamiriro ekunze akaoma emaindasitiri, kubva kufefetera mafuta anopisa zvakanyanya kusvika kumabasa ekuchera ane acidic. Kusiyana nemamita emakanika angangoda kutsiviwa zvizere makore ese maviri kusvika matatu, EMF inochengetwa zvakanaka inogona kugara kwemakore gumi kana kupfuura, ichideredza mashandisirwo emari. Pamusoro pezvo, kugona kwavo kuyera huwandu hwakasiyana hwemvura—kubva kumvura inofambisa mvura (mvura, makemikari) kusvika kuslurry dzakasimba (simende, zvinwiwa zvechikafu)—kunobvisa kudiwa kwekudyara mumhando dzakasiyana dzemita dzemaitiro akasiyana. Mugadziri wezvekudya nezvinwiwa, semuenzaniso, anogona kushandisa EMF imwechete isingagadzirisike zvakanyanya kuti aongorore kuyerera kwesirapu mumutsetse wemabhodhoro uye kuburitswa kwemvura yakasviba, kudzivirira mutengo wemamita akasarudzika pakushandisa kwega kwega. Kushanduka-shanduka uku hakungorerutsi manejimendi yezvinhu chete asiwo kunoderedza nguva yekudzidziswa kwevashandi, vanongoda kudzidza mashandiro emudziyo mumwe chete.
Zvakakosha kuti maEMF asingagadzirisike zvakanyanya haakanganisi kurongeka kwekuyera kuti zvive nyore—chinhu chikuru chinonetsa maindasitiri uko data rekuyerera rakarurama rinokanganisa zvakananga kunaka kwechigadzirwa, kutevedzera mitemo, uye kugadzirisa zviwanikwa. Tekinoroji yavo yemagetsi inopa mwero wekururamisa we ± 0.5% kusvika ± 1% yehuwandu hwakazara, kunyangwe mumamiriro ekuyerera kwakashata kana kana mvura ine zvinhu zvakamiswa. Kune fekitari yemakemikari inosanganisa zvinhu zvakagadziriswa, iyi nhanho yekururamisa inovimbisa kuenderana kwebatch, ichideredza marara kubva pakuderedzwa zvakanyanya kana kuderedzwa. Kune mashandiro emafuta negasi, inobvumira kuteverwa kwakarurama kwekufambiswa kwemafuta, kudzivirira kurasikirwa kwemari kubva mukukanganisa kwekuyera. Uyezve, maEMF mazhinji emazuva ano asingagadzirisike zvakanyanya anosanganisira maficha akangwara akadai sedhijitari, kugona kwekutarisa kure, uye nyevero dzekuzviongorora. Zvishandiso izvi zvinobvumira vashandisi kutevera data rekuyerera munguva chaiyo, kuona matambudziko anogona kuitika (semuenzaniso, mwero wekuyerera usina kujairika) asati awedzera, uye kuita calibration chaiyo—zvichideredza nguva yekumira. Mugadziri wemishonga, semuenzaniso, anogona kushandisa kutarisa kure kuona kuti kuyerera kwemvura kwakachena kunosangana nezvinodiwa neFDA 24/7, pasina kutumira mainjiniya mumakamuri ekuchenesa kuti vaongorore kakawanda.
Munguva iyo mabasa emaindasitiri anotarisana nekumanikidzwa kukuru kwekuderedza mitengo, kuvandudza kuchengetedzeka, uye kuwedzera kugadzirwa, mita dzemagetsi dzisingagadziriswi zvakanyanya dzinoonekwa semhinduro inoshanda. Dhizaini yavo isina chikamu inobvisa kutenderera kunodhura kwekugadzirisa, kugara kwavo kwenguva refu kunowedzera hupenyu hwemidziyo, kushanduka-shanduka kwavo kunoderedza mari inoshandiswa, uye kunyatsochengetedza kunaka kwavo uye kutevedzera mitemo. Kune vatariri vemafekitori nemapoka ekushanda, masvomhu acho akajeka: kuisa mari muEMF isingagadziriswi zvakanyanya hakusi kungotenga mita yekufambisa mvura chete - asi kuisa mari mukutsungirira kwenguva refu kwekushanda. Ingave ichishandiswa mukurapa mvura, kugadzira, kana kugadzira simba, zvishandiso izvi zvinoratidza kuti kushanda zvakanaka kwemutengo uye kugona kuyera zvinogona kufamba pamwe chete - kushandura chishandiso chenguva dzose kuita chinotungamira kubudirira kwemaindasitiri.
