Abstract
This invention relates to a method of registering the tophography and height level of the charged mass in a blast furnace. A distance meter for measurement by means of direct reflection against the surface is placed in the vicinity of the top of the blast furnace, appropriately at an inspection window located there. The distance meter is equipped with an aiming device with which the measuring direction of the distance meter is aimable at selected parts of the surface of the charged mass. A computing unit such as a micro- or minicomputer calculates, on the basis of the siting of the distance meter, the set angles of the aiming device for measurement direction and the results of performed distance measurements, calculates the positions for the different measuring points and presents these in analog or digital form.
