Leak Detection

Product Leak Detection

Background and current market status


Damage from localized torrential downpour	Damage from earthquake

Damage from oil leak	Aged building / super-tall skyscraper

Essential elements of life...
Water, oil, various chemical solutions, etc.

However,
they can theaten us.

· Natural disaster
: Global warming (desertification/localized downpour),
flood, earthquake and tsunami, river flood, water deficiency, etc.

· Manmade hazard
: Water / soil / air contamination due to chemical solution or gas, etc.

· damage to building, facilities
: Increased risk due to super-tall skyscrapers, reduced concrete strength, increased aging speed, etc.

Advantages og film-type water leak sensor


easy installation	Easy to cut and possible to reassemble!	free movement of worker / vehicle	Easy to finish alarm by simple cleaning up	Cusromized mark printing available	competitive price

Comparision with other companies' products

FLOWTECH CO., LTD. film-type water leak sensor can be installed anywhere without limitation, and can replace all types of water leak sensors at a lower price. The shorter length covers the point sensor, and the longer one covers the cable/ metal band sensor area, and it can be easily installed on wall, floor, machine, as well as pipes without additional bracket as it is adhesive.
