METHOD AND DEVICE FOR MEASURING THE HEIGHT OF A PRODUCT IN SURROUNDINGS HAVING A THERMAL BEHAVIOUR DIFFERENT FROM THAT OF THE PRODUCT TO BE MEASURED, PARTICULARLY FOR MEASURING THE HEIGHT OF SNOW

摘要

ABSTRACT OF THE DISCLOSUREA measuring rod carrying a plurality of temperaturesensors distributed over its height is placed in such a way that atleast its lower part is embedded in the product of which the heightis to be measured. Signals produced by the sensors andrepresenting the temperatures in the locations of the varioussensors on the rod are picked up and the variation in time of thepicked-up signals is monitored in order to identify the lowestsituated sensor which delivers a signal of which the variation ishigher than a predetermined threshold.
