we have LPG spherical Tank and we want to install DP Xmtr
for level measurement.below are the physical measurements
Total height of tank is 1850 mtr but 0% level is 1000mm
above bottom and 100% level is 450 below upper side.What is
the LRV and URV and please mention the formula .The SG of
LPG is 0.53 and Wet Leg method will be used.

Answer Posted / ghalib
first the question is not clear,the total height of the
tank given in mtr(1850)but the 0% is above 1000mm,ok,but
100% level is 450 below upper side,(this 450 is in what-mm
or meter,pls make it clear
