1. I-UOL evulekile imitha yokugeleza yesiteshi ye-flume ne-weir ehlukahlukene
Le mitha ingalinganiswa ngokuqondile ngezinga loketshezi.Uma isetshenziswa esilinganisweni sokugeleza kwesiteshi esivulekile, idinga ukufaka i-flume ne-weir.I-weir ingase iguqule ukugeleza ibe ileveli yezinga loketshezi lomsele ovulekile.Imitha ikala izinga lamanzi ku-water weir groove, bese ibala izinga lokugeleza ngokuhambisana nokugeleza kwamanzi kwemisele ehambisanayo yamanzi weir ku-microprocessor. ngaphakathi kwemitha.Imifantu emikhulu eyi-weir grooves i-Bacher grooves, i-weir engunxantathu kanye ne-rectangular weir.Lapho kulinganiswa izinga le-liquid, ubuchwepheshe be-echo be-ultrasonic buyamukelwa, futhi i-level gauge igxiliwe ngaphezu kwendawo yokubuka izinga lamanzi le-weir.Indiza yesidluliseli yegeji yeleveli iqondaniswe ngokuqondile nendawo yamanzi.Ngaphansi kokulawula kwe-microcomputer, imitha yezinga le-ultrasonic idlulisa futhi ithole amaza e-ultrasonic.Ngokusho kwe-Hb=CT/2 (C isivinini somsindo wegagasi le-ultrasonic emoyeni, i-T isikhathi samaza e-ultrasonic emoyeni), ibanga elingu-Hb phakathi kwemitha yezinga le-ultrasonic kanye nezinga loketshezi elilinganiselwe liyabalwa, ukuze ukuthola ukuphakama kwezinga le-liquid Ha.Ekugcineni, ukugeleza koketshezi kutholakala ngokuya ngefomula yokubala ukugeleza.Ngenxa yokulinganisa okungathintana naye, ingasetshenziswa ezindaweni ezinokhahlo.Imitha yokugeleza kwesiteshi evulekile ilungele amadamu, imifula, amaphrojekthi okongiwa kwamanzi, imigudu yokuphambukisa amanzi emadolobheni, isikhungo samandla ashisayo sokupholisa imigudu yokuphambukisa emfuleni, ukugezwa kwendle emiseleni yokulahla nokukhipha, izimo zokusebenza zokuchithwa kwamanzi angcolile kanye namaphrojekthi okonga amanzi kanye nokuchelela kwezolimo. iziteshi.
2. DOF6000 i-serial Area velocty i-flowmeter yesiteshi esivulekile sesiteshi noma ipayipi eligcwaliswe kancane
Imitha ye-velocity flow meter ihlanganisa isivinini sokugeleza kanye nesilinganiso sezinga le-liquid, yamukela isimiso se-Doppler se-ultrasonic sokulinganisa izinga lokugeleza.Lapho ukala izinga le-liquid, inzwa ibekwe phansi noma eduze nendawo yamanzi.Ngenzwa ye-hydrostatic pressure, ikhebula lesignali yokuphakelwa kwamandla linomsebenzi wokungenisa umoya.Ingcindezi yomoya endaweni yamanzi isetshenziswa njengengcindezi yereferensi yenzwa ye-hydrostatic pressure ukuze kulinganiswe ingcindezi yoketshezi, ukuze kubalwe ubude bezinga loketshezi.I-area-velocity ultrasonic flowmeter ifaneleka ukulinganisa eziteshini ezivulekile noma amapayipi angagcwali anobubanzi obukhulu kuno-300mm wokukhipha indle namanzi angcolile, imifudlana ehlanzekile, amanzi okuphuza namanzi olwandle.
