Concept
Water depth directly correlates to Water pressure once ambient air pressure is compensated for.
In other words, determine the Pressure at a point under water, then compensate for Air Pressure near the same point above the water, and Water Depth should result.
Components
- eTape Strips to measure fluid depth up to 32" - These work by detecting the hydrostatic pressure of liquid squeezing the strip and resulting in a change in resistance.
