In a method for continuous determination of the wall thickness of extrudates having a hollow profile, in particular hoses (flexible tubes), it is provided according to the invention that both inside and outside the hollow profile fixed, mutually opposite sensors are used for the optoelectronic emission of radiant power directed onto the passing wall of the hollow profile, and the reflected radiant power is received, and via an evaluation circuit the respective distance from the sensor to the wall of the hollow profile is determined from the difference between emittted and reflected radiant power, and thus the geometry of the hollow profile is determined. <IMAGE>
