A level measuring device with an integratable lens has a radar level meter and an angle adjusting assembly. The radar level meter has a horn antenna and a lens antenna assembly mounted on a signal transceiving end of the radar level meter. The lens antenna assembly has a housing and a lens antenna.
A level measuring device with an integratable lens has a radar level meter and an angle adjusting assembly. The radar level meter has a horn antenna and a lens antenna assembly mounted on a signal transceiving end of the radar level meter. The lens antenna assembly has a housing and a lens antenna. The housing is hollow and receives the horn antenna therein. One end of the housing is connected to the lens antenna, and the other end of the housing is connected to the signal transceiving end of the radar level meter. The angle adjustment assembly is mounted around the housing. As the lens antenna assembly covers the horn antenna, the horn antenna is less likely to be damaged. Additionally, the housing of the lens antenna assembly is connected with the angle adjusting assembly for angle adjustment of the combined horn antenna and lens antenna assembly.
