Refer to the drawing of a water storage tank with a differential pressure (D/P) level detection system (see figure below).
The level detector is being used in a level control system that was calibrated to maintain tank level at 80 percent when the tank water temperature was 100°F.
If tank water temperature gradually increases and stabilizes at 150°F, the level control system will cause actual tank level to…
A. remain stable at 80 percent.
B. increase and stabilize above 80 percent.
C. oscillate and then stabilize at 80 percent.
D. decrease and stabilize below 80 percent.
