Differential pressure gauge works based on the differential pressure between the vapour and____.
Direct Answer
Option B: liquid
A differential pressure gauge for tank level measurement works by sensing the pressure difference between the vapour space above the liquid and a point submerged in the liquid. This pressure differential directly correlates to the hydrostatic head of the liquid, thus indicating the tank's contents.
