Abstract

Method and equipment for measuring the height of the surface of a material bed (2) conveyed on a conveyor belt (1). In the method, there is used a laser telemeter (3; 3'), which is a laser telemeter (3; 3') scanning over the material bed, operated according to a measurement principle based on the time of propagation of light.
