Pombi yakavharwamita dzekuyereraanoshandiswa zvakanyanya pakufambisa mvura ine pressure yakavharirwa, nepo ma open channel flowmeters akagadzirirwa kuyera kuyerera kwemvura pamusoro isina pressure. Mvura inoyerera pasi pesimba renyika mumigero yakavhurika yakadai senzizi, migero yekudhonza mvura, migero yemvura yakasviba yefekitori uye mapaipi etsvina emumaguta asina kuzara mapaipi, zvichigadzira nzvimbo yekuyera yakasiyana iyo electromagnetic kana ultrasonic pipeline metres isingagoni kuchinjika nayo. Ma open channel flowmeters anosanganisa kuona kuyerera kwemvura nema flumes kana ma weirs akajairwa kuti averenge kuyerera kwemvura, zvichipa kushanda kwakaderera, kwakagadzikana uye kuchinjika kwakafara, uye ave michina yakajairika yekutarisa zvakatipoteredza, tsvina yemumaguta, kudiridza uye mapurojekiti ekubvisa mvura mumaindasitiri pasi rese.
Pfungwa huru yekuyerama flowmeter enzira yakavhurikaZvinoenderana nehukama hwe hydraulic pakati pehuwandu hwemvura ne flow rate. Zvinoenderana ne hydraulics formulas, flow volume mu fixed open channel section inosarudzwa zvakasiyana ne fluid level height. Mazhinji masisitimu akakwana ane zvikamu zviviri zve core: level sensor uye flow calculation transmitter. Ultrasonic level probes ndiwo anonyanya kushandiswa. Akaiswa akamira pamusoro pemvura, anoburitsa mafungu eruzha kuti aone daro re real-time kusvika kumvura, obva ashandura daro kuita data re depth depth range. Hydraulic formulas dzakavakwa mukati dzeParshall flumes, rectangular weirs uye triangular V-notched weirs dzinochengetwa mu transmitter. Mushure mekufananidza parameters ye channel structure, mudziyo unoverenga otomatiki flow instantaneous uye unounganidza total flow volume. Mamwe ma models epamusoro anoshandisa contactless radar level sensors, ayo anoshanda zviri nani munzvimbo dzakaoma dzine dense water vapor, furo kana floating sludge pamusoro pemvura.
Zvichienzaniswa nezvishandiso zvekuyerera kwepombi, ma "open channel flowmeters" ane mabhenefiti akasiyana akakodzera mamiriro ekuyerera kwemvura. Chekutanga, haadi kusangana ne "medium" yakayerwa. Ma "ultrasonic" uye "radar sensors" akaiswa pamusoro pe "channel", kudzivirira ngura, kukura uye kuvharika kunokonzerwa ne "sediment", "fibers", "chemical residues" mu "sewage". Hapana zvikamu zvinofamba zvakanyoroveswa, saka mari yekugadzirisa uye yekutsiva inoderedzwa zvakanyanya. Chechipiri, haagadzirisi kuyerera kwemvura uye hapana kurasikirwa nekumanikidzwa. Kusiyana nema "pipeline metres" anogara munzvimbo yepombi uye anodzivisa kufamba kwemvura, zvivakwa zvekuyera "open channel" hazvikanganisi kumhanya kwemvura kwekutanga, izvo zvakakosha kune network dze "sewage" dzemaguta dzisingakwanise kutsungirira kuvharika kwemvura. Pamusoro pezvo, michina iyi ine huwandu hwakakura hwekuyera, inokwanisa kubata kuyerera kudiki munguva dzisiri dzepamusoro uye kuyerera kwemvura kwakanyanya panguva yekugadzira fekitori kana mvura zhinji.
Migero yekuyerera kwemvura yakavhurika inofukidza zvikamu zvitatu zvikuru zvekushandisa. Kudzivirirwa kwezvakatipoteredza mumaguta ndiwo musika mukuru. Zvivakwa zvekuchenesa tsvina mumaguta zvinoisa pamigero yekubuditsa mvura yakasviba, zvichipa ruzivo rwepamutemo rwekutarisa nharaunda uye huwandu hwezvinhu zvinosvibisa. Mvura yemvura yemumaguta nemigero yetsvina yakasanganiswa inoshandisawo mita iyi kupatsanura data remvura yemumvura neyetsvina yekuchenesa kuti pave nekushanda zvakanaka kwenetwork yemapaipi. Chechipiri, madhiraivha emaindasitiri anoshandisa michina iyi zvakanyanya. Makambani emucheka, makemikari, chikafu nekuchera mvura anoburitsa mvura yakasviba kuburikidza nemigero yakavhurika; mita yetsvina yakavhurika inoteedzera huwandu hwemvura yekubuditsa mvura kudzora kushandiswa kwemvura uye kuona kuti mitemo yekubuditsa mvura inoenderana. Chechitatu, kuchengetedza mvura yekurima kunonyanya kutsamira pakuyera migero yakavhurika. Migero yekudiridza yemumapurazi, nzira dzekudiridza dzinodzora mvura uye migero yekugovera mvura inoshandisa mita yetsvina yakavhurika yemhando yeflume kuverenga kushandiswa kwemvura yekudiridza, kutsigira kugoverwa kwezviwanikwa zvemvura zvakaenzana uye manejimendi ekuchengetedza mvura yekurima.
Nzira yakazaruka yemazuva ano yakangwaramita dzekufambavane mabasa ekutaurirana edhijitari akakwana. RS485 Modbus-RTU inobuda inobvumira kubatana nePLC, makabati ekudzora maindasitiri uye mapuratifomu ekutarisa zvakatipoteredza ari kure. Madhata akavakirwa mukati anochengetedza zvinyorwa zvenhoroondo yekuyerera, uye maalarm akawandisa anongoerekana aitika kana mvura isina kuchena ikabuda, senge kubuda kwemvura kunokonzerwa nekusvibisa maindasitiri kamwe kamwe. Midziyo yese inoshanda zvakanaka pasi pekupisa kwakakura uye inogona kuchinjika kune kuiswa kwekunze kwemhepo ine dhizaini yedzimba dzisingapindi mvura uye dzisingapindi guruva.
Mukupfupikisa, ma "open channel flowmeters" anozadza nzvimbo isina chinhu chekuyera kuyerera kwesimba remagetsi risingadzvinyirike iro mita dzemapaipi dzechinyakare dzisingagoni kufukidza. Nekuyera kusingabatanidzwi, mutengo wakaderera wekugadzirisa uye kuchinjika kwakasimba kwezvakatipoteredza, anoita basa risingatsiviwi mukutarisa tsvina, kudhonza mvura mumaindasitiri uye kudiridza mvura. Sezvo manejimendi epasi rose emvura uye kutarisa kuburitswa kwemhepo munzvimbo zvichiwedzera kuoma, masisitimu ekuyera kuyerera kwemvura munzvimbo dzakavhurika akangwara acharamba achiwedzera mugove wawo wemusika senzvimbo dzakakosha dzekutarisa nharaunda yemvura.
