To be published.
3.1
“at” station
station currently occupied by the EODR instrument
3.2
“back” station
station to the rear of the "at" station presently occupied by the EODR instrument
3.3
bisect
sighting of the centre of a target through the telescope of a EODR instrument
3.4
changing face
rotation of both horizontal and vertical circles of the EODR instrument by 200 gon
3.5
“forward” station
station forward of the "at" station presently occupied by the EODR instrument
3.6
misclosure
difference between the sum of the horizontal angles measured between the various stations of a complete traverse
of the tank and the sum of the theoretical angles for the same traverse
3.7
station
position from which measurements of angles and slope distance are made
3.8
tribrach
device, set on a tripod, which, by adjusting three or more foot screws, is set in a horizontal plane and upon which
surveying instruments are mounted
4Principle
The tank and its surrounds are visually inspected and, having calculated the number of stations required, the siting
of the measurement stations is chosen.
Tripods, together with their respective measuring equipment, are placed at the initial stations. To establish the
position of the "at" station, angular and distance measurements are made from the initial "at" station to the initial
"back" and "forward" stations. Angular and distance measurements to the top and base of the tank are then taken
together with tangential angular measurements bisecting (3.3) the tank shell to the right and left of the station.
These measurements are made at the required positions on each course. The tripods at the initial "back" and "at"
stations are left in position to enable closure of the traverse on completion of the calibration.
From each of the subsequent, predetermined stations, angular and distance measurements to the top and base of
the tank are then taken, together with tangential angular measurements bisecting (3.3) the tank shell to the right
and left of the station.
In moving to each new station, the old "forward" station becomes the new "at" station and the old "at" station the
new "back" station. The final measurements are made from an "at" station which was the initial "back" station; the
final "forward" station is the initial "at" station.
These measurements, after any adjustments for misclosure, allow the calculation of three dimensional coordinates
which are fitted into a matrix describing the tank mathematically. The circumferences at the various vertical
positions on the tank shell are calculated from this information and the capacity table developed in accordance with
ISO 7507-1.

To be published.
3.1
“at” station
station currently occupied by the EODR instrument
3.2
“back” station
station to the rear of the "at" station presently occupied by the EODR instrument
3.3
bisect
sighting of the centre of a target through the telescope of a EODR instrument
3.4
changing face
rotation of both horizontal and vertical circles of the EODR instrument by 200 gon
3.5
“forward” station
station forward of the "at" station presently occupied by the EODR instrument
3.6
misclosure
difference between the sum of the horizontal angles measured between the various stations of a complete traverse
of the tank and the sum of the theoretical angles for the same traverse
3.7
station
position from which measurements of angles and slope distance are made
3.8
tribrach
device, set on a tripod, which, by adjusting three or more foot screws, is set in a horizontal plane and upon which
surveying instruments are mounted
4Principle
The tank and its surrounds are visually inspected and, having calculated the number of stations required, the siting
of the measurement stations is chosen.
Tripods, together with their respective measuring equipment, are placed at the initial stations. To establish the
position of the "at" station, angular and distance measurements are made from the initial "at" station to the initial
"back" and "forward" stations. Angular and distance measurements to the top and base of the tank are then taken
together with tangential angular measurements bisecting (3.3) the tank shell to the right and left of the station.
These measurements are made at the required positions on each course. The tripods at the initial "back" and "at"
stations are left in position to enable closure of the traverse on completion of the calibration.
From each of the subsequent, predetermined stations, angular and distance measurements to the top and base of
the tank are then taken, together with tangential angular measurements bisecting (3.3) the tank shell to the right
and left of the station.
In moving to each new station, the old "forward" station becomes the new "at" station and the old "at" station the
new "back" station. The final measurements are made from an "at" station which was the initial "back" station; the
final "forward" station is the initial "at" station.
These measurements, after any adjustments for misclosure, allow the calculation of three dimensional coordinates
which are fitted into a matrix describing the tank mathematically. The circumferences at the various vertical
positions on the tank shell are calculated from this information and the capacity table developed in accordance with
ISO 7507-1.

3.8
embase
dispositif, installé sur un trépied, placé sur un plan horizontal par ajustement de trois vis de réglageouplus, et sur
lequel les instruments de topographie sont montés
4Principe
Le réservoir et ses alentours sont inspectés visuellement, et aprèsavoir établi le nombre de points de station
nécessaires, l’emplacement des points de station est sélectionné.
Les trépieds et leur équipement respectif de mesurage sont placés aux points de station origines. Les mesures
d’angles et de distance sont effectuées à partir du point de station «stationencours» jusqu’aux points de station
«station précédente» et «station suivante»,afin d’établir la position de la «station en cours». Les mesurages des
angles et de la distance à la partie supérieure et à la base du réservoir sont effectués en une fois, ainsi que les
mesurages tangentiels d’angle de visée (3.3) de la paroi du réservoir à droite et à gauche du point de station. Ces
mesurages sont effectués pour chaque virole aux emplacements adéquats. Les trépieds aux points de «station
précédente» et «station en cours» sont laissés en place pour s’assurer que le cheminement aura été complet à la
fin du jaugeage.
À partir de chaque point de station ainsi déterminéà l’avance, le mesurage des angles et des distances au bord
supérieur et à la baseduréservoir est effectué,enmême temps que les mesurages angulaires qui visent
tangentiellement la paroi du réservoir à droite et à gauche du point de station.
En se déplaçant sur chaque nouvelle station, l’ancien point de station «arrière» devient la «station en cours»,et
l’ancien emplacement «station en cours» devient le point de «station avant». Le dernier mesurage à partir de la
«station en cours» qui était auparavant le point de «station précédente» est effectué, la dernière «station suivante»
est maintenant la «station en cours» initiale.

Aprèsavoir été corrigésde l’écart de fermeture, les mesurages, qui permettent de calculer les coordonnées en
trois dimensions, sont inscrits dans un tableau qui est la description mathématique du réservoir. C’est à partir de
ces informations que les circonférences sont calculées à différents points verticaux de la robe du réservoir, et le
barème du réservoir est établi conformément à l'ISO 7507-1.
