1. Depth Sensing There is a linear relationship between pressure and depth. There is a linear relationship between pressure and depth. The following is the mathematical representation of the relationship: The following is the mathematical representation of the relationship: ΔP = γh ΔP = γh –ΔP  Pressure Difference –γ  Specific Weight of Liquid –h  Change In Elevation
