Abstract

A system and associated method for monitoring pressure of water at a sub-surface water location. The system includes a chamber, enclosing a fluid, and a fluid line. The system includes a differential pressure sensor with first and second fluid pressure inputs connected to the chamber and the fluid line, respectively. The system includes a first valve configured to have a first position in which the chamber is in fluid communication with the fluid line through the first valve and configured to have a second position in which the chamber is blocked from fluid communication with the line. The system includes a second valve configured to have a first position in which the fluid line is blocked from fluid communication with the water at the sub-surface location and is configured to have a second position in which the line is in fluid communication with the water through the second valve.
