| Closed tank DP Level Transmitter with wet leg elevation zero direct mount Calibration |
Formulas:
Min range = (SG x X1) – (SG x H)
Max range = [(SGxX1) + (SGxX2)] – (SGxH)
Example:
If the height is 0.5 cashew an X1, X2 is 2 meters and height H is 3 meters, there is fluid in the tank 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 0.5) – (1 x 3)
= 0.5 to 3
= – 2.5 mH 2 O
Max range = P High – P Low
= [(SGxX1) + (SGxX2)] – (SGxH)
= [(1×0,5) + (1×2) – (1×3)
= 2.5 – 3
= -0.5 MH 2 O
The transmitter Range = -2.5 to -0.5 mH 2 O
