Kurongeka neKuyerera uye Kudzika
Kuti calibration ishande, transducer inoda kurongeka uye yakatwasuka.nekuyerera.Nepo Ultraflow QSD 6537 zviridzwa zvakanamirwa zvichinongedza mukuyerera, ivoinogona kunongedzerwa zasi kwerwizi nekurasikirwa kushoma kweiyo calibration yechokwadi.Ungada kuita izviapo kusvibiswa kwechiso che sensor idambudziko.Chero kuyerera kwekona mundege yakachinjika kuchadarokuderedza kasipidhi yakanyorwa.
Iyo Ultraflow QSD 6537 chiridzwa chinofanirwa kuiswa mumvura yakatarisana nepamusorokuverenga kwakadzama kuyera nemazvo (~ +/- 10 deg), kana kusiri kudzika kungaverengeka zvisina kururama.uye naizvozvo kudzika kwakanyorwa kunogona kunge kuri kunyora zvisizvo.
Pakarepo Versus "Avhareji" Velocity
Paunoona Ultraflow QSD 6537 velocities, ivo vanozoonekwa vachisiyana negumi muzana kana kupfuura.kubva pa scan kuenda ku scan pane dzimwe saiti.Nekuti Ultraflow QSD 6537 inonzwa zvakanyanya kune akasiyanamumavelocities, iwe unokwanisa kuona kushanduka kwechisikigo mugero.Kunyange zvazvo kubuda mumugero kungave kwakagadzikana kwenguva yakati, iyovelocity kugovera kunogara kuchichinja.Mafashama enzizi akasiyana anodzungaira kubva kune rumwe rutivi kuenda kune rumweuye mubhedha kumusoro sezvavanofambira pasi nemugero.Mhepo inotenderera uye eddies irizvinotakurwa zvichidzika kurukova kwenhambo refu apo dzichiora zvishoma nezvishoma.Hydrographers ichashandiswakuita ichi chiito chakabviswa pamwe ne mechanical inertia yemamita azvino uye nguvapairi kuyerwa kunoitwa nguva.Zvisinei vose vachange vaona kuti chiyero chemarevolutions emamita azvino anosiyana panguva yenguva.Kuramba uchimhanya matanda panzvimbo imwe ine Ultraflow QSD 6537 inoratidza aya cyclicvelocity pulsations.Hunhu huchave hwakasiyana kune akasiyana saiti uye huchasiyana nedischarge.Ma Cycles anowanzo sanganisira kuchinjika kwenguva pfupi (masekonzi mashoma) akafukidzwa pamusorokureba cyclic kuchinja (kusvika maminetsi akawanda).Kuputika kwenguva refu kunogonawo kuonekwakunyanya muhova huru kana mafashamo.Kana uchienzanisa Ultraflow QSD 6537 velocity uye mechanic ikozvino mita kuverenga, iyokuratidzwa kunofanirwa kucherechedzwa kwenguva yakareba kuti ifungidzire zvinoreva zvakaverengerwa.Iyo UltraflowQSD 6537 ichaita yakawanda yeiyi kugadzirisa mukati asi kana yekunze logger iri kushandiswakurekodha kuverenga kweavhareji kunogonawo kuitwa pano izvi zvichabatsira kudzikisira mafupi mafupikusiyana.
Shanduko yeLogged to Mean Velocity
Iyo yakayerwa velocity data inogona kugadziridzwa panguva yekugadziriswa kweposita kuratidza zvinorevavelocity yechiteshi.Izvo zvinhu zvinoshandiswa zvichave zvakanangana nesaiti uye zvinofanirwa kutsanangurwamushandisi.Izvi zvinoitwa nekuwana nhanho yekumhanya nemaitiro akajairwauye nokuienzanisa neavhareji yakarogwa velocity.Kana zvakakodzera nzira iyi inofanira kuvainodzokororwa pakubuda kwakasiyana-siyana
Uko hukama hwakaoma kana husina kugadzikana, kururama kweiyi nzira kunokanganiswa.
Mumamiriro ekuyerera kwelaminar chiteshi chinoreva velocity inogona kutarisirwa kuva pakati pe90%uye 110% yelogged velocity.
Munzira diki (taura 500mm dhayamita pombi) chinhu chinogona kunge chiri pedyo ne100% seinomiririra nzvimbo yekuyerera ichave "yaonekwa" ne Ultraflow QSD 6537 uye yakabatsiraiyo yakadhindwa velocity.
Muzviteshi zvakakura chete nzvimbo iri padyo neUltraflow QSD 6537 ndiyo icha "onekwa" uye iyohukama hunoenderana nekuti chikamu ichi chinopindirana sei kune yakatwasuka uye yakachinjika velocitykugovera mugero.Chiridzwa chiri pakati perukova chinowanzoitaiva munzvimbo yakakwira velocity.Nekudaro mune yakadzika chiteshi Ultraflow QSD 6537 inogona kungoona iyochikamu chinononoka cheiyo velocity profile.
