9.4 No-Well Monitoring, Double-Wall Tank
The space between the walls of a double-wall tank is the
interstitial
space, and it is an ideal location for liquid sensors.
If the
outside
tank wall develops a leak, groundwater enters the
interstitial space and the liquid sensor triggers an alarm.
If the
inside
wall develops a leak, the tank contents enter the interstitial
space and both sensors indicate an alarm condition.
Error! Reference source not found. shows a typical sensor layout for a
double-wall tank.
