|Density Measurement using DP Transmitter for closed tank with dry leg|
The formulas for calculating the tranmitter LRV and URV are;
HP Side/LRV/4ma = LSmin
LP Side/URV/20ma = LSmax
L = Closed tank maximum measured level
Smax = Maximum process specific gravity
Smin = Minimum process specific gravity
Note: This calculation is only used for closed tank with dry leg and for constant level application.
