Closed Tank Level Measurement with wet leg and Transmitter installed below Tapping Point

DP LEVEL TRANSMITTER WET LEG CALIBRATION

This calculation used for closed tank level measurement with wet leg type calibration

The formulas for calculating transmitter URV and LRV are as follows:

 HP Side or LRV or Transmitter 0%    =  X.S1 - Y.S2 
 LP Side or URV or Transmitter 100% =  S1(X+H) - Y.S2

Where
S1  =  Specific gravity of tank liquid or process liquid.
S2  =  Specific gravity of wet leg
H   =  Tank Height
X   =   Distance between transmitter and HP tapping point.
Y   =   Wet Leg Height

 NOTE:
 1. The Parameters H,X can be entered in any units like mmh20, inh20 but must be same
 2. If wet leg Y is filled with same process liquid in the tank then S2=S1.
 3. If wet leg Y is filled with different liquid (other than tank process liquid) then enter specific gravity of wet leg liquid in S2.
