Ultrasonic panguva yekufambisamita dzekuyererazvishandiso zvepamusoro zvinoshandiswa kuyera mwero wekuyerera kwemvura negasi mukati memapaipi nedzimwe nzira dzekufambisa mvura. Mamita aya anoshandisa musimboti wekuyera nguva kuona kumhanya kwenzvimbo inoyerera nepaipi, zvichipa mhinduro dzekuyera kuyerera kwakarurama, kwakavimbika, uye kusingapindi. Muchinyorwa chino, tinoongorora musimboti wekushanda, mashandisirwo, uye mabhenefiti emamita ekuyerera kwemvura panguva yekufamba.
Nheyo yeMamita ekufamba kwenguva
Mamita ekuyerera kwemhepo panguva yekufamba kwemhepo anoshanda zvichienderana nepfungwa yekuyera nguva inotora kuti acoustic kana electromagnetic pulse ifambe pakati pemapoinzi maviri mumvura. Kuyera uku kunosanganisira kutumira chiratidzo kubva kune imwe transducer uye kunyora nguva inotora kuti chiratidzo chifambe nemumvura kuenda kune inogamuchira. Musiyano wenguva pakati penzira dzekumberi nedzekumashure unoshandiswa kuverenga kumhanya kwekuyerera kwemhepo.
Semuenzaniso, muma ultrasonic transit-time flow mita, mafungu eruzha anoshandiswa kuona mwero wekuyerera kweruzha. Kana kuyerera kweruzha kuri kufamba nenzira imwecheteyo ne sound pulse, nguva inotorwa pakati pe transducers ipfupi. Kusiyana neizvi, kana kuyerera kweruzha kuri kufamba nenzira yakasiyana, nguva inotorwa inowedzera. Nekuverenga nemazvo mutsauko uripo mukuyera kwenguva idzi, flow mita inogona kuona mwero wekuyerera kweruzha uye, mushure mezvo, mwero wekuyerera kweruzha.
Zvakanakira zveMamita ekufamba kwenguva
1. Kuyera Kusingapindire
Chimwe chezvakanakira zvikuru zvema "transit-time flow meters" ndechekuti haapindiri. Sezvo asingade kusangana zvakananga nemvura, akakodzera kuyera zvinhu zvakaoma kana zvine njodzi pasina kukanganisa kuyerera kana kukanganisa kusimba kwehurongwa.
2.Kururama Kwakakwirira
Mamita ekuyerera kwemvura panguva yekufamba kwemhepo anopa kunyatsojeka pakuyera kuyerera kwemvura nekuda kwekukwanisa kwawo kuyera kusiyana kwenguva nemazvo. Izvi zvinotungamira mukuvandudzwa kwekushanda uye kushanda zvakanaka mumaindasitiri uko mwero wekuyerera kwemvura wakarurama unokosha.
3. Kushandiswa Kwakasiyana-siyana
Ma flow metres aya anogona kushandiswa kuyera huwandu hwakasiyana hwezvinwiwa nemagasi mumaindasitiri akasiyana-siyana. Anowanzoshandiswa mumabasa akadai senzvimbo dzekuchenesa mvura, mapaipi emafuta negasi, uye munzvimbo dzekugadzirisa makemikari.
4. Kutarisa Kuyerera Kwenguva Yechokwadi
Nanguva yekufambisamita dzekuyerera, vashandi vanogona kugara vachitarisa mwero wekuyerera kwemvura panguva chaiyo. Izvi zvinobatsira mukuvandudza mashandiro, kuona kuchengetedzeka, uye kugonesa kugadziriswa kwekufanotaura nekuona kusagadzikana kwekuyerera kwemvura kunogona kuratidza kuvharika kana kutadza kushanda zvakanaka kwemidziyo.
5. Kugadzirisa Kushoma
Sezvo ma "transit-time flow meters" asina zvikamu zvinofamba kana kusangana zvakananga ne "flow medium", anowanzo da kugadziriswa kushoma kana tichienzanisa nema "mechanical flow meters", ayo anogona kusakara.
Mashandisirwo eMamita ekufamba kwenguva
1. Kuyerwa kweUltrasonic Flow
Tekinoroji yekufamba kwenguva inowanzo shandiswa nema ultrasonic flow metres, ayo anoshandiswa zvakanyanya pakuyera mvura, utsi, uye gasi rechisikigo mumapaipi. Kugona kwavo kuyera mwero wekuyerera kwemvura diki nehombe nemazvo kunoita kuti vave chishandiso chakakosha muzvikamu zvakaita sekugoverwa kwemvura nekugadzirwa kwesimba.
2. Kutarisa Mapaipi
Muindasitiri yemafuta negasi, ma "Transit-time flow meters" anoshandiswa kutarisa kuyerera kwemafuta asina kucheneswa, gasi rechisikigo, uye zvigadzirwa zvakacheneswa mukati memapaipi. Mamita aya anopa data rechokwadi panguva chaiyo, iro rakakosha pakugadzirisa mafambiro emvura uye kuona kana paine kudonha kwemvura kana zvimwe zvinetso zvesisitimu.
3. Maindasitiri emakemikari nemishonga
Kuyera kuyerera kwakarurama kwakakosha mumaindasitiri emakemikari nemishonga, uko kunodiwa kuyera kwakarurama kwekugadzirwa kwechigadzirwa. Mita yekuyerera kwekufamba kwenguva inopa mhinduro yakavimbika kune izvi zvinoshandiswa, ichivimbisa kutevedzera mitemo yakasimba yemhando yepamusoro uye kuchengetedzeka.
4. Kuyera Kuyerera Kwakangwara
Nguva yekufambisamita dzekuyererazviri kuramba zvichibatanidzwa muhurongwa hwekuongorora mafambiro emvura hwakangwara hunobvumira kutarisa nekudzora uri kure. Maitiro aya anogonesa vashandisi kutarisira kuiswa kwakasiyana-siyana kubva panzvimbo iri pakati, zvichivandudza mashandiro uye zvichideredza kudiwa kwekushandisa nemaoko.
Mukupedzisa,mita dzekuyerera kweultrasonic dzinofamba panguva yekufambisaZvinomiririra kufambira mberi muhunyanzvi hwekuyera kuyerera kwemvura. Magadzirirwo avo asingapindiri, kunyatsorongeka, kushanduka-shanduka, uye zvinodiwa zvishoma zvekuchengetedza zvinoita kuti vave sarudzo inosarudzwa mumaindasitiri akasiyana-siyana kubva pakuchenesa mvura kusvika kumafuta negesi. Nekushandisa kugona kwekutarisa panguva chaiyo uye kugona kwekuongorora metering, mabhizinesi anogona kugadzirisa mashandiro avo, kuvandudza kuchengetedzeka, uye kuderedza nguva yekushanda. Kunyangwe uri kutsvaga nzira inoshanda yekuyera kuyerera kwemvura mupaipi kana kutarisa masisitimu akaomarara emaindasitiri, mameter ekuyerera kwemhepo panguva yekufamba anopa mhinduro yemazuva ano yezvinodiwa zvekuyera.
