1. Umthelela wengcindezi esilinganisweni esithembekile semitha yeleveli yerada
Ukusebenza kwemitha yeleveli ye-radar akuthintwa ukuminyana komoya lapho kuthunyelwa amasiginali e-microwave, ngakho-ke imitha yeleveli ye-radar ingasebenza ngokujwayelekile ngaphansi kwesimo se-vacuum nengcindezi. Kodwa-ke, ngenxa yomkhawulo wesakhiwo somtshina we-radar, lapho ingcindezi yokusebenza esitsheni ifinyelela ebangeni elithile, imitha yezinga le-radar izokhiqiza iphutha elikhulu lokulinganisa. Ngakho-ke, ekulinganisweni kwangempela, kufanele kuqashelwe ukuthi ayikwazi ukudlula imboni evunyelwe Inani lokucindezela ukuze kuqinisekiswe ukwethembeka kwesilinganiso se-radar level gauge.
2.Ithonya lokushisa esilinganisweni esithembekile se-radar level gauge
Imitha yeleveli ye-radar ikhipha ama-microwave ngaphandle kokusebenzisa umoya njengendawo yokusabalalisa, ngakho-ke ukuguquka kwezinga lokushisa lendawo kunomthelela omncane esivinini sokusakazeka se-microwave. Kodwa-ke, izingxenye zenzwa ne-antenna zemitha yezinga le-radar azikwazanga ukumelana namazinga okushisa aphezulu. Uma izinga lokushisa lale ngxenye liphezulu kakhulu, lizothinta ukulinganisa okuthembekile nokusebenza okuvamile kwemitha yezinga le-radar.
Ngakho-ke, lapho usebenzisa imitha yeleveli ye-radar ukukala imidiya yezinga lokushisa eliphezulu, kuyadingeka ukusebenzisa izindlela zokupholisa, noma ukugcina ibanga elithile phakathi kophondo lwe-antenna nezinga eliphakeme kakhulu loketshezi ukuze ugweme uthi ukuthintwa ukushisa okuphezulu.
