Mamita ekuyereraZvishandiso zvekuyera zvakakosha mumaindasitiri emakemikari, ekurapa mvura, epeturu uye ekugadzira. Kuti vaongorore mashandiro ekuyera kwemuchina wekuyeresa flow meter, zvinhu zviviri zvakakosha zvekururama zvinogamuchirwa zvakanyanya: kururama kwekuverenga uye kururama kwechiyero chakazara. Nyanzvi dzakawanda dzeinjiniya dzinowanzo vhiringidza zviratidzo zviviri izvi, zvichikonzera kusarudzwa kwezvishandiso zvisina kunaka, kutonga kwedata kusina kururama uye kunyange kudzora maitiro asina kugadzikana. Kujekesa mutsauko uripo pakati pekururama kwekuverenga nekururama kwechiyero chakazara kwakakosha pakushandiswa kwemamita ekuyerera kwakarurama, kuongorora data uye kugadzirisa maitiro emaindasitiri.
Kururama kwechiyero chose, kunowanzo nyorwa se %FS (chikamu cheChikero Chizere), inzira yechinyakare yekuenzanisa kururama kwemidziyo yekuyera. Inotsanangura kukanganisa kwakanyanya kunobvumidzwa zvichibva pane chiyero chakazara chemuchina wekuyera. Kukosha kwechiyero chose kunoreva muganho wepamusoro wechiyero chinoyerwa chemuchina wekuyerera. Kana chiyero chose chawanikwa, kukanganisa kwakakwana kwakaverengerwa ne %FS kunogara kwakagadzika mukati menguva yese yekuyera. Semuenzaniso, kana flow meter iine chiyero chekuyera che 0 kusvika 100 m³/h uye kururama kwakazara kwechiyero che ±1%, kukanganisa kwayo kwakanyanya kwakakwana kunogadzika pa ±1 m³/h panzvimbo dzese dzekuyera.
Chinhu chinonyanya kuoneka chekururama kwechiyero chose ndechekuti ine kukanganisa kwakasimba. Chinhu chakanaka chiri mukuverenga kuri nyore uye kugadzirisa zviri nyore kwefekitori, ndosaka michina yakawanda yemazuva ano inoshandiswa kugadzira michina.mita dzekuyererauye ma "basic differential pressure flow meter" anoshandisa chiyero ichi. Zvisinei, ine dambudziko guru mukuyerwa kwe "low-flow" mamiriro ezvinhu. Kana "flow rate" chaiyo iri pedyo ne "low-flow" muganhu we "range", "fixed absolute error" inoverengera chikamu chikuru che "qualitative value", zvichikonzera kudzikira kukuru kwe "relative accuracy". Izvi zvinoreva kuti zvishandiso zvine "full scale accuracy garandi" chete hazvigone kuchengetedza "high-precision" mumamiriro ekushanda asina mutoro wakawanda uye akasiyana-siyana.
Kusiyana neizvi, kuverenga kwakarurama, kunoratidzwa se %RD (chikamu cheKuverenga), inzira yekunyatsorurama inoshandiswa zvakanyanya muma flow metres emazuva ano akadai se electromagnetic flow metres uye ultrasonic flow metres. Kusiyana ne fixed full scale error, kuverenga kwakarurama kunoverenga kukanganisa kunobvumirwa zvichibva pakukosha kwekuyerera kwakayerwa panguva chaiyo. Kukanganisa kwakakwana kunochinja-chinja nekuchinja kwehuwandu hwekuyerera chaiko, zvichiita kuti kuve nekururama kwakasimba munzvimbo zhinji dzekuyera.
Tichitora kuverenga kwakarurama kwe ±0.5%RD semuenzaniso, kana chiyero chekuyerera chakayerwa chiri 100 m³/h, kukanganisa kwakazara i ±0.5 m³/h; kana chiyero chekuyerera chikadzikira kusvika 10 m³/h, kukanganisa kwakazara kunodzikira kusvika ±0.05 m³/h zvinoenderana. Iyi nzira yekutsiva kukanganisa inoshandura simba inoita kuti chishandiso chirambe chakanyatsojeka kungave kuyera kuyerera kwakanyanya kana kuyerera kwakaderera. Iri ndiro mukana mukuru wekuverenga kwakarurama, zvichiita kuti chikodzere mamiriro akaoma eindasitiri ane makuru.kuchinja-chinja kwekuyererauye zvinodiwa pakuyera kwepamusoro.
Musiyano mukuru uripo pakati pemitemo miviri iri muchiyero chekuverenga zvikanganiso uye kushanda kwechikamu chidiki. Kururama kwakazara kunoshandisa muganho wepamusoro wechikamu chakazara sechiyero, nekukanganisa kwakasimba asi kusinganyatsojeka. Kururama kwekuverenga kunotora kuverenga kwenguva chaiyo sechiratidzo, nekukanganisa kwakasimba uye kugadzikana muchikamu chose. Mukusarudza kweinjiniya inoshanda, kururama kwakazara kwakakodzera mamiriro ekushanda ane kugadzikanakuyerera uye kushanduka kudiki, nepo kuverenga kwakarurama kuri chiyero chinodiwa chekufamba kwakasiyana-siyana, kuyera kwakanyatsojeka uye mamiriro ekutengeserana.
Mukupedzisa, kunzwisisa musiyano uripo pakati pekururama kwekuverenga nekururama kwechiyero chose kunobatsira mainjiniya kutonga nemazvo mashandiro chaiwo ema flow metres. Kusarudza mwero wakarurama wekururama zvichienderana nehunhu hwekugadzira kunogona kudzivirira zvikanganiso zvekuyera, kuvandudza kuvimbika kwedata remaindasitiri, uye kuve nechokwadi chekuti mashandiro akachengeteka, akagadzikana uye asingadhuri emabasa ekugadzira maindasitiri.
