Refer to the drawing of a water storage tank with two tank differential pressure (D/P) level indicators (see figure below).
Two D/P level indicators are installed on a large water storage tank. Indicator 1 was calibrated at 100°F water temperature and indicator 2 was calibrated at 200°F water temperature.
Assuming both indicators are on scale, which indicator will indicate the lower level?

B. Indicator 2 at all water temperatures
C. Indicator 1 below 150°F, indicator 2 above 150°F
D. Indicator 2 below 150°F, indicator 1 above 150°F
