Abstract

a. Appareil pour la mesure des distances, qui se base sur le principe du temps de propagation, comprenant des moyens de correction de la mesure relativement à l'indice de réfraction de l'air le long de la section à mesurer. b. Il comprend un récepteur de valeurs mesurées pour au moins une des grandeurs - température de l'air, pression de l'air et humidité relative de l'air -, récepteur qui peut être détaché de l'appareil et qui peut recevoir une ou plusieurs valeurs mesurées en des endroits ou à des moments donnés et les mémoriser ou les changer en valeurs moyennes. c. Applications courantes.at. Apparatus for measuring distances, which is based on the principle of propagation time, comprising means for correcting the measurement relative to the refractive index of the air along the section to be measured. b. It includes a receiver of measured values for at least one of the quantities - air temperature, air pressure and relative humidity of the air -, receiver which can be detached from the device and which can receive one or more values measured in places or at given times and memorize them or change them into average values. vs. Common applications.
