Radar open channel flowmeter mudziyo wekuyera kuyerera kwemvura usingabatanidzwe, une radar current meter uye radar water level meter, uchishandisa nzira yekuyera kusingabatanidzwe, hazvisi nyore kuti iparadzwe netsvina, haikanganisike netsvina, inogona kushandiswa munzvimbo dzakaoma dzemvura dzine tsvina kana sediment. Radar antenna ine kutungamira kwakanaka, small beam Angle, kugona kwakasimba uye kudzivirira kukanganiswa kwakasimba, izvo zvinovandudza zvikuru kurongeka kwekuyera uye kuvimbika.
Chiyero chekufambisa mvura cheRadar chinogadzirwa nepfungwa yeDoppler effect, mafungu emagetsi anogadzirwa pamusoro pemvura paanenge achishanda, uye mafungu emagetsi anopararira paanosangana nepamusoro pemvura inofamba, uye anoumba manzwi. Nekuti frequency ye echo inogamuchirwa inodzikiswa kusvika pamwero wakati kana ichienzaniswa nefrequency yekutumira, kumhanya kwemvura kunogona kuwanikwa neDoppler frequency equation, uye chinangwa chinofamba chichagadzira chiratidzo chekubuda kwefrequency yakaderera muradar sensor. Kuwanda kwechiratidzo ichi kunoenderana nekumhanya kwekufamba, uye amplitude inoenderana nedaro, reflectivity, uye saizi yechinangwa chinofamba. Doppler shift inoenderana nekumhanya kwekufamba. Sisitimu ye fixed point radar flowmeter inogona kuwana radar probes dzakawanda, izvo zvakaenzana nekuisa mitsara yakatwasuka yekuyera yakawanda, uye kuverenga kuyerera kwechikamu pamwe chete nezvikamu zvechikamu.
Chiyero chemvura chakavhurika cheradar chinoshandiswa zvakanyanya mukuongorora kwemvura, kutarisa zviwanikwa zvemvura pamusoro, kuyerwa kwemvura munzvimbo yekudiridza nekuyera, kutarisa hurefu hwenzira yerwizi, kutarisa mvura yemuguta, kutarisa kwenzvimbo yemagetsi emvura, kutarisa kwezvakatipoteredza kwenzvimbo yemagetsi nezvimwe, zvakakodzera kutsanangurwa uye zvikamu zvisina kurongeka, sisitimu yekuyera kuyerera kweradar inogona kuita kuti pave negwara rakavhurika, kuyerera kwerwizi kwechisikigo, kuunganidzwa kwedata remvura otomatiki uye kutarisa panguva chaiyo.
