Abstract:
A filling level measuring device with a transmitting and receiving device and a waveguide, one end of which is coupled to the transmitting and receiving device and an other end of which is immersed in a filling material, to which waveguide electromagnetic waves from the transmitting and receiving device can be conducted, while electromagnetic waves reflected in the waveguide can be used in the transmitting and receiving device for measuring the filling level,wherein the other end exhibits a wave absorption device for at least partial absorption of the conducted electromagnetic waves; and wherein the waveguide is a single-wire, a double-wire, a coaxial, or a hollow guide probe and the wave absorption device is a body that is positioned on the other end and consists of wave-damping material that is inert with respect to the filling material and that exhibits a dampening gradient that increases towards that end of the waveguide immersed in the filling material.
