ABSTRACT:
A hydraulic monitoring method and apparatus provides a monitoring system which replaces the void or air space within the interstitial/annular volume of double wall piping with an inert environmentally safe, food grade, hydraulic liquid. Monitoring of the liquid provides rapid, real time sensing of any alarm phase or mode. The method identifies primary piping failures or any secondary containment piping breech or wall penetration with an immediate level change within the fluid sensor monitor reservoirs. If the fluid level decreases, a breech in the secondary containment piping is evidenced. If the fluid level increases, a primary piping wall failure is indicated. This level change can be electronically monitored for rapid system alert and/or system/pump shutdown.
