Abstract
To reduce a reflection wave that causes a stray signal wave in a level meter. The level meter includes a sensor substrate, a radio wave shaping member, a dielectric lens, and a radio wave absorbing member. The radio wave shaping member includes an element case covering an internal space including a transmitting unit and a receiving unit mounted on a sensor substrate, a waveguide having one end in electromagnetic communication with the element case, and a horn having a radio wave path gradually expanding from the other end of the waveguide toward a traveling direction of a transmitted radio wave. The dielectric lens is provided at the leading end of the horn, and deflects the radio wave from the transmitter through the radio wave shaping member to the object. The radio wave absorbing member is provided along the inner wall of the element case and absorbs radio waves.
