The impulse tubes must be filled with process fluid or fill
fluid such as glycol. Additionally the specific gravity of
the fill fluid must be calculated in reference to the
process fluid being measured
Glycerin (Specific Gravity=1.26) for the impulse tubes a
correction must be made.
DP span of 100”= physical height difference of impulse tubes
on vessel
SG of fluid being measured (Oil = 0.68)
Glycerin filled tubes (SG = 1.26)
Since the Low Pressure Leg will be filled with Glycerin we
multiply the span by the SG of the Fill Fluid
100” x 1.26 = 126” so the Lower Range value will be -126”
Span will be the LRV – (SG of fluid) x ( tank Level span) = 68”
-126” + 68” = -58”
-126 LRV
-58 URV
