I-Radar open channel flowmeter iyithuluzi lokulinganisa ukugeleza okungathintani, eliqukethe imitha yamanje ye-radar kanye nemitha yamazinga amanzi ye-radar, esebenzisa isilinganiso esingathintani, akulula ukugqwala yindle, ayithinteki yindle, ingasetshenziswa endaweni eyinkimbinkimbi yamanzi enokungcola noma indle. I-antenna ye-radar inesiqondiso esihle, i-Angle encane ye-beam, ikhono elihlanganisiwe kanye nokulwa nokuphazamiseka okunamandla, okuthuthukisa kakhulu ukunemba nokuthembeka kokulinganisa.
I-flowmeter ye-radar evulekile yesiteshi yenziwa ngesimiso somphumela we-Doppler, amagagasi kagesi azokhiqizwa ebusweni bamanzi lapho esebenza, futhi amagagasi kagesi azohlakazeka lapho ehlangana nobuso bamanzi ahambayo, bese enza ama-echoes. Ngenxa yokuthi imvamisa ye-echo etholiwe ivinjelwa ngezinga elithile uma iqhathaniswa nemvamisa yokudlulisa, ijubane lobuso bamanzi lingatholakala nge-Doppler frequency equation, futhi ithagethi ehambayo izokhiqiza isignali yokukhipha imvamisa ephansi ku-radar sensor. Imvamisa yalesi signali incike esivinini sokuhamba, futhi ubukhulu buncike ebangeni, ekukhanyeni, kanye nosayizi wethagethi ehambayo. I-Doppler shift ilingana nesivinini sokunyakaza. Uhlelo lwe-fixed point radar flowmeter lungafinyelela ama-radar probe amaningi, okulingana nokubeka imigqa eminingi yokulinganisa eqondile, kanye nokubala ukugeleza kwesigaba kuhlanganiswe namapharamitha esigaba.
I-radar open channel flowmeter isetshenziswa kabanzi ekuhlolweni kwamanzi, ukuqapha izinsiza zamanzi angaphezulu, ukulinganisa amanzi endawo yokunisela kanye nokulinganisa, ukuqapha ubude besistimu yomfula, ukuqapha amanzi okukhipha amanzi kamasipala, ukuqapha ukukhishwa kwemvelo kwesiteshi samandla kagesi kanye neminye imikhakha, efanelekile ngezincazelo kanye nezigaba ezingajwayelekile, uhlelo lokulinganisa ukugeleza kweradar lungafeza isiteshi esivulekile, ukugeleza komfula kwemvelo, ukuqoqwa kwedatha yamanzi okuzenzakalelayo kanye nokuqapha kwesikhathi sangempela.
