Ma flow metres ndiwo maturusi akakosha ekuyera kuyerera kwemvura mumaindasitiri akasiyana-siyana. Pakati pemhando dzakasiyana dze flow metres dziripo, area velocity flow metres dzinowanzo shandiswa mumashandisirwo anoda kuyerwa kwekuyerera kwemvura yakavhurika, senge nzizi, hova, uye masisitimu emvura inoyerera. Zvisinei, zvakakosha kunzwisisa miganho yekushandisa ye area velocity flow metres kuti uve nechokwadi chekuti zviyero zvakarurama uye zvakavimbika.
Mamita ekuyerera kwenzvimbo anoshanda nekuyera kumhanya kwekuyerera uye nzvimbo yepakati pechiteshi kuti averenge mwero wekuyerera. Kunyange zvazvo mita idzi dzekuyerera dzichishandiswa zvakasiyana-siyana uye dzichigona kushandiswa mumhando dzakasiyana-siyana, pane zvimwe zvipingamupinyi zvinoda kufungwa nezvazvo.
Chimwe chezvinhu zvikuru zvinotadzisa mashandisirwo emamita ekuyerera kwemhepo pamusoro pemvura imhando yemvura iri kuyerwa. Mamita ekuyerera aya akakodzera kuyera kuyerera kwemvura yakachena, mvura yakasviba nezvimwe zvinwiwa zvisingakanganisi. Zvisinei, anogona kunge asina kukodzera kuyera kuyerera kwemvura ine huwandu hwakawanda hwematope, marara, kana gasi, sezvo izvi zvichigona kukanganisa kururama kwekuyera.
Chimwe chinhu chakakosha kufunga nezvacho ihukuru nechimiro chemugero kana mugero wakaisirwa mugero wekufambisa mvura. Mamita ekuyerera kwemhepo akagadzirwa kuti ashande zvinobudirira mumigero yakavhurika uko mafambiro emvura akafanana. Maumbirwo emugero asina kurongeka, kukotama kwakapinza kana zvipingamupinyi zvinogona kukanganisa maitiro ekuyerera kwemvura uye kukanganisa kurongeka kwekuyera.
Kumhanya kwemvura (velocity range) kwemvura kunobatsirawo pakuona kana nzvimbo yekuongorora kumhanya kwemvura yakakodzera kushandiswa kwakati. Ma flow metres aya akagadzirirwa kuyera huwandu hwakasiyana hwemvura inoyerera, asi anogona kunge asina kukodzera kushandiswa kwemvura yakaderera kana yakakwira zvakanyanya. Muchiitiko ichi, dzimwe nzira dzekuyera kufamba kwemvura dzinogona kunge dzakakodzera.
Pamusoro pematambudziko emuviri, zvakakosha kufunga nezvemamiriro ekunze ayo chiyereso chekuyerera kwemhepo chichaiswa. Zvinhu zvakaita sekupisa, hunyoro, uye kuratidzwa kwezuva zvinogona kukanganisa mashandiro emuyereso wekuyerera uye hupenyu hwebasa. Zvakakosha kusarudza muyereso wekuyerera unogona kutsungirira mamiriro chaiwo enzvimbo yekushandiswa.
Pamusoro pezvo, kana tichifunga nezvemiganhu yekushandisa mita yekuyerera kwemhepo pamusoro, zvinodiwa pakuiisa nekugadzirisa zvinofanirawo kufungwa nezvazvo. Kuiisa kwakakodzera, kusanganisira nzvimbo ye sensor uye calibration yemidziyo, kwakakosha pakuyera kwakarurama. Kuti flow meter yako irambe yakavimbika, kuigadzirisa nguva dzose uye kuichenesa kunodiwawo.
Pasinei nemiganhu iyi yekushandisa, mita yekuyerera kwekukurumidza kwenzvimbo ichiri chishandiso chakakosha chekuyera kuyerera kwenzira yakavhurika mumhando dzakasiyana siyana dzekushandisa. Kuyera kuyerera kwakarurama uye kwakavimbika kunogona kuwanikwa nekunzwisisa zvipingamupinyi uye kusarudza mita yekuyerera yakakodzera yekushandisa chaiyo.
Muchidimbu, mita dzekufamba kwemhepo dzinoshandiswa munzvimbo dzine zvipingamupinyi zvekushandiswa kwadzo izvo zvinofanirwa kutariswa pakusarudza mabasa ekuyera kufamba kwemhepo. Kunzwisisa zvipingamupinyi izvi uye kuona kuti mita yekufamba kwemhepo yakakodzera mamiriro chaiwo enzvimbo yekushandiswa kwakakosha kuti uwane zviyero zvekufamba kwemhepo zvakarurama uye zvakavimbika. Nekufunga nezvezvinhu izvi, mukana wemita dzekufamba kwemhepo pamusoro pemvura unogona kuwedzerwa munzvimbo dzakasiyana-siyana dzemaindasitiri nedzenharaunda.
