I-flowmeter yeradar evulekileyo yetshaneli

I-Radar open channel flowmeter sisixhobo sokulinganisa ukuhamba kwamanzi esingadibaniyo, esiquka imitha yamandla eradar kunye nemitha yamanzi eradar, esebenzisa umlinganiselo ongadibaniyo, akulula ukuba idliwe lindle, ayichaphazeleki yintlenga, ingasetyenziswa kwindawo entsonkothileyo yamanzi enezingcolisi okanye intlenga. I-antenna yeradar ine-directivity elungileyo, i-Angle encinci yemitha, amandla aqinileyo kunye nokuchasana okunamandla, okuphucula kakhulu ukuchaneka kokulinganisa kunye nokuthembeka.
I-flowmeter evulekileyo yeradar yenziwa ngomgaqo we-Doppler effect, amaza e-electromagnetic aza kuveliswa kumphezulu wamanzi xa esebenza, kwaye amaza e-electromagnetic aza kusasazeka xa edibana nomphezulu wamanzi ohambayo, aze enze ii-echoes. Ngenxa yokuba i-frequency ye-echo efunyenweyo iphantsi kwinqanaba elithile xa kuthelekiswa ne-frequency yokudlulisela, isantya somphezulu wamanzi sinokufunyanwa nge-Doppler frequency equation, kwaye ithagethi ehambayo iya kuvelisa isignali yokuphuma engaphantsi kwi-sensor yeradar. I-frequency yale signal ixhomekeke kwisantya sokuhamba, kwaye i-amplitude ixhomekeke kumgama, ukubonakalisa, kunye nobukhulu bethagethi ehambayo. I-Doppler shift ihambelana nesantya sokuhamba. Inkqubo ye-fixed point radar flowmeter inokufikelela kwiiprobes ezininzi zeradar, ezilingana nokubeka imigca ethe nkqo yokulinganisa emininzi, kunye nokubala ukuhamba kwecandelo kunye neeparameter zecandelo.

I-flowmeter yeradar evulekileyo isetyenziswa kakhulu kuphando lwamanzi, ukujonga imithombo yamanzi angaphezulu komhlaba, ukulinganisa amanzi kunye nokulinganisa indawo yokunkcenkceshela, ukujonga ubude benkqubo yomlambo, ukujonga amanzi okuhambisa amanzi kamasipala, ukujonga ukukhutshwa kweendawo ezikummandla wamanzi kunye namanye amasimi, afanelekileyo kwiinkcukacha kunye namacandelo angacwangciswanga, inkqubo yokulinganisa ukuhamba kweradar inokufezekisa i-open channel, ukuhamba komlambo kwendalo, ukuqokelelwa kwedatha yamanzi ngokuzenzekelayo kuyo yonke imozulu kunye nokujonga ngexesha langempela.
