Closed tank DP Level Transmitter with wet leg Zero elevation Calibration

Schematic Diagram of a Closed tank DP Level Transmitter with wet leg Zero elevation Calibration
Closed tank DP Level Transmitter with wet leg Zero elevation Calibration

Formulas:

Min range = – SG . H

Max range = – SG . (H-X)

Example:

If the height of an X is 2 meters and height H is 2.5 meters, there is fluid in the tank which has a density of 1 g / cm3, what is the range of calibration on the Trasmitter?

SG = 1

Min range = – 1 x (2.5 – 0)

= – 1 x 2,5 m
= – 2.5 mH 2 O

Max range = -1 X (2.5 – 2)

= -1 X 0.5 m
= -0.5 MH 2 O

The Transmitter Range = -2.5 to -0.5 mH 2 O

  • Dear Sir

    We need to have calculation to calculate the Differential Level in mm of H2o to exact level in Cum for Gas Application

    We have Cryogenic Tank filled with Nitrogen Gas @ -187 deg cent.

    We are putting differential gauge which is giving reading in mm of H20. we need to convert the same in to cum of gas

    Kindly advice
