Tank measurements

•

Tank reference distance, R

. The R distance is defined as the dis-

tance between the 

dipping datum point

 (zero level) and the 

tank 

reference point

.

•

RTG reference distance, G

. G is the distance between the 

tank 

reference point

 (hand dip nozzle) and the 

RTG reference point

. 

The RTG reference point is underneath the RTG flange, see Fig-
ure 1-5.

•

Minimum level distance, C

. C is the distance between the 

dip-

ping datum point

 (zero level) and the 

bottom of the tank

.

•

Note the distance (mm) from max product level to RTG reference 
point. 

Note!

The G value is defined as positive if the Tank Reference point is located 
above the RTG Reference point.
