Vula i-flowmeter yesiteshi, ngokwezimiso ezihlukene zokulinganisa, ihlukaniswe yaba yi-ultrasonic open channel flowmeter kanye ne-Doppler open channel flowmeter, konke kusiteshi esivulekile noma isilinganiso sesiteshi semishini yokuqapha ukugeleza kwamanzi.Isistimu yokuqapha i-flowmeter ye-channel evulekile, elungele indawo yokugcina amanzi, umfula, iphrojekthi yokonga amanzi, ukuhlinzekwa kwamanzi emadolobheni, ukuthuthwa kwendle, ukuchelela emapulazini, izinsiza zamanzi kanye nokunye unxande, umzila ovulekile we-trapezoid kanye nesilinganiso sokugeleza kwe-culvert.Isetshenziswe kabanzi eminyakeni yamuva.
Ultrasonic open channel flowmeter
Kusetshenziswa ubuchwepheshe besiteshi esivulekile, ngokusekelwe endleleni yokubala izinga lokugeleza kwamanzi, izinga lokugeleza litholwa ngokulinganisa ukuphakama kwezinga loketshezi, kuhlanganiswe usayizi wejometri we-weir groove evamile, i-slope coefficient, ukunemba kwesiteshi, irempu ye-hydraulic, i-coefficient yokulungiswa kwendiza eqondile. wezinga lokugeleza, bese kubalwa nge-microprocessor ngaphakathi kwensimbi.Ngenxa yokulinganisa okungathintani nabo, ama-flowmeters wesiteshi avulekile angasetshenziswa ezindaweni ezinokhahlo.Ngaphansi kokulawulwa kwe-microcomputer, i-flowmeter yesiteshi evulekile idlulisa futhi ithole igagasi le-ultrasonic, futhi ibala ibanga phakathi kwe-flowmeter yesiteshi evulekile kanye nendawo ewuketshezi elinganiselwe ngokuya kwesikhathi sokudlulisela, ukuze kutholwe ukuphakama kwezinga le-liquid.Ngenxa yokuthi kunobudlelwano obuthile obulinganayo phakathi kwezinga loketshezi kanye nesilinganiso sokugeleza, izinga lokugeleza koketshezi Q lingatholwa ngokuya ngefomula yokubala.
I-Doppler evulekile ye-flowmeter yesiteshi
Indlela yokulinganisa yokuxhumana iyamukelwa, inzwa ibekwe ngaphansi kwesiteshi, futhi phakathi kwama-probe amabili, isistimu ibala isivinini sokuphuma ngokuhambisana nomphumela wesikhathi we-Doppler, bese iguqula ukugeleza okusheshayo endaweni ye-cross-sectional. indawo yezinzwa ngokuya ngefomula.
