Abstract
The invention is a measuring arrangement for measuring a fill level in a container with a radar level gauge according to the delay principle, which comprises an adaptation for reducing electromagnetic radiation reflected by the surfaces of the wall of the container as well as a method for optimizing the adaptation and for reducing stray radiation, for example radiation reflected by the container walls, with here display devices indicating if stray radiation is sufficiently reduced.
Claims10
A measuring arrangement comprising
- a container allowing that its interior is filled with a fill good,
- a radar measuring device arranged outside the container and aligned to the interior chamber of the container, embodied as a radar level gauge, which emits electromagnetic waves of at least one wavelength and capable to detect the progression of the reflected electromagnetic radiation of at least one wavelength as an echo curve,
- a wall arranged between the interior chamber of the container and the radar measuring device, at least partially permeable for the electromagnetic radiation of at least one wavelength,
- a detection unit for detecting the echo curve,
- an adaptation for reducing electromagnetic radiation reflected from the surfaces of the wall, wherein the adaptation comprises at least one self-adhesive synthetic film, or synthetic plate, or one glued to the wall or resting on the wall, at least partially permeable for electromagnetic radiation of at least one wavelength, which is glued or otherwise adhered to the wall such that the electromagnetic radiation pulses emitted by the radar level gauge penetrate at least one synthetic film.
