# Closed tank DP Level Transmitter with wet leg elevation zero remote mount Calibration

The DP level transmitter installed below HP tapping point with wet leg.Schematic Diagram of a Closed tank DP Level Transmitter with wet leg elevation zero remote mount Calibration Closed tank DP Level Transmitter with wet leg elevation zero remote mount Calibration 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)
= [(1×1) + (1×2) – (1×4,5)
= 4 to 4.5
= -0.5 MH 2 O

The transmitter Range = -3.5 to -0.5 mH 2 O

1. Easy to learn.. but all students needs to calculate the range by themselves.. beacause one printing mistake is there.
