Formulas:
Min range = (SG x X1) - (SG x H)
Max range = [(SGxX1) + (SGxX2)] - (SGxH)

Example:
If the height is 1 meter an X1, X2 is 3 meters and a height H is 4.5 meters, in the tank there is cairin which has a density of 1 g / cm3, what is the range of calibration on the transmitter?
SG = 1
Min range = P High - P Low
= (SG x X1) - (SG x H)
= (1 x 1) - (1 x 4.5)
= 1 -4.5
= - 3.5 mH 2 O
Max range = P High - P Low
= [(SGxX1) + (SGxX2)] - (SGxH)
= [(1x1) + (1x2) - (1x4,5)
= 4 to 4.5
= -0.5 MH 2 O
The transmitter Range = -3.5 to -0.5 mH 2 O
