Example: – A close vessel filled with two different density materials that is LPG (0.5 g/cm³) and Water (1 g/cm3), A remote seal DP transmitter installed at the height of LP tapping with 1.1065 g/cm3density material filled in capillary. The height of HP and LP Tapping is 1000 mm.Than what is the Range of Transmitter?
Given :-
S1 = 0.5 g/cm3
S2 = 1 g/cm3
Sf = 1.1065 g/cm3
L=1000
D=0
H= L+D = 1000
LRV = DP = {(S1*L) + (Sf*D)} – (Sf*H)
LRV = {(0.5*1000)+(1.1065*0)}-(1.1065*1000)
= {500+0}-1106.5
LRV = -606.5 mmH2O
URV = {(S2*L) + (Sf*D)} – (Sf*H)
URV = {(1*1000)+(1.1065*0)}-(1.1065*1000)
= {1000+0}-1106.5
URV = – 106.5
