Leakage within a tank that was not easily accessible or visible for human inspection

How SAM GUARD® Helped

  • SAM GUARD detected a drop in the tank level as soon as it was installed, and issued an alert.
  • Plant engineers carried out an on-site inspection and discovered a leakage in the tank’s manual valve.
  • The valve was fixed, stopping the leak.


  • The tank supplies cooling water to the evaporator.
  • If the level had continued to drop, the evaporator would have major temperature regulation issues.
  • Without the ability to regulate its temperature, the evaporator would have failed.
  • Tank level had been dropping for 3 months without anyone noticing.
