Method for calibrating distance measuring device e.g. radar level gauge for determining liquid level in container, involves measuring distance between distance measuring device and object with respect to reflected measurement signal

摘要

The method involves mounting a distance measurement device (2) on a test track (3). A planar target object (4) is arranged for reflecting the measurement signal back into distance measurement device slidably arranged on test track. The distance (d) between the distance measuring device and planar target object is measured with respect to the reflected measurement signal. The measured value (dm) is compared with a reference value (dref) to detect the inclination of target object. An independent claim is included for system for calibrating distance measuring device.
