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 / nestor
let us consider at 100% 450meters upper side so the wet leg measures:
1850 - (450 meter + 1 meter) = 1399 meter
so height(specific gravity) = 1399 (0.53) = 741.47 meter
span = URV-LRV
LRV = 1 meter(0.53) = 0.53 meter
so URV = span+LRV = 741.47 + 0.53 = 742 meter
