Water leak detectors
Abstract
Abstract WATER LEAKS FROM CONTAINERS OR CONDUITS ARE DETECTED BY CHEMICAL INDICATORS. THESE MAY ACCUMULATE WATER AT THE LEAK SOURCE TO GIVE A CLEARLY DISCERNIBLE COLOUR CHANGE. SUCH INDICATOR MAY BE PROVIDED IN THE FORM OF A NONCORROSIVE EASILY REMOVABLE PAINT OR A NON-CORROSIVE ADHESIVE TAPE WITH OR WITHOUT A PROTECTIVE TRANSPARENT COVER SO AS TO FACILITATE DIRECT APPLICATION TO A METAL SURFACE. THE INDICATOR CAN COMPRISE (A) A CARRIER AND A STRONTIUM CHROMATE/SILVER SULPHATE COUPLE AS THE ACTIVE INDICATOR, OR (B) A CARRIER AND A POTASSIUM FERROCYANIDE/FERRIC SULPHATE-INERT BRIGHTENER COUPLE AS THE ACTIVE INDICATOR, OR (C) A CARRIER AND A POTASSIUMN FERROCYANIDE/CUPRIC SULPHATE-INERT BRIGHTENER COUPLE AS THE ACTIVE INDICATOR. THERE MAY ALSO BE PRESENT AN ADHESIVE COMPONENT, A FUGITIVE DISPERSING COMPONENT AND A WATER MISCIBILITY IMPROVING COMPONENT.
