RADAR LEVEL GAUGE INCLINATION SYSTEM

摘要

A radar level gauge arrangement for determining the fill level of a filling material in a tank is disclosed, which arrangement is mounted on a hatch of a tank and/or on a support which is adapted to be mounted on a hatch of a tank. The arrangement comprises a transmitter for transmitting measuring signals at least along a first axis for determining the fill level of the tank; a receiver for receiving echo signals corresponding to the distance to the surface; a first processing circuitry for receiving the echo signals and to determine a fill level of the tank based on the echo signal; an inclinometer attached to the support and adapted to generate an inclination output corresponding to the inclination relative the surface normal; a second processing circuitry for generating, based on the inclination output, an angular output when there is an angular difference between the first axis and the surface normal. The arrangement also comprises a presenter for communicating information about the angular difference externally of said system, or a communication path for communicating the angular output to said first processing circuitry.
