Bulk material measurement packages are described including the preferred embodiment of an automated instrument package (AIP) suited to mount on the inside ceiling of a large silo. The gimbaled AIP vertical mounting bracket rotates in an approximate 360~ azimuth. An instrument housing is mounted to the vertical mounting bracket, and it rotates approximately 190~ in a vertical plane. The instrument housing has at least one range finding sensor such as a scanning laser to measure the top surface contours of the bulk material. The instrument housing can also contain other sensors wuch as air and quality instruments including temperature, humidity, spectral recognition sensor to detect gran/material type and/or flow rate, gas detectors for sniffing off- odors/spoilage/or safety problems, and live video. Optionally grain penetrating radar (GPR), time domain reflectometry (TDR), ultrasonics, and portable sensors are taught as well as alternate packaging.

L'invention porte sur des dispositifs de mesure de matériaux en vrac dont le préféré, qui est un dispositif automatique (AIP) se montant sous le toit d'un gros silo. L'étrier vertical de fixation de l'AIP monté sur cardan, qui peut tourner en azimut sur environ 360·, porte le boîtier de l'instrument qui peut lui tourner sur environ 190· dans un plan vertical. Ledit boîtier abrite au moins un télémètre, par exemple à balayage laser permettant de mesurer les contours de la surface supérieure du matériau en vrac; il peut également comporter d'autres détecteurs, par exemple de la qualité, de la température et de l'humidité de l'air, des détecteurs de reconnaissance spectrale identifiant le type de matériau en grain et/ou son débit, et des détecteur de gaz identifiant les émanations, les altérations du matériau et les situations de danger. On peut en outre y monter facultativement un radar de pénétration des grains, un réflectomètre temporel, un détecteur à ultrasons, des détecteurs portables, etc.
