Abstract
An improved device for the detection of leakage is achieved when the device includes at least two components, of which at least one is capable of migrating with the liquid within the carrier, and forming a distinct colour or other detectable signal with the first component. Such device is not sensitive to normal, ambient humidity and the colour signal formed is resistant to being diluted or rinsed away in cases of abundant or repeated leakage.
Claims19
A device for the detection of leakage of a liquid, characterized in that said device comprises a carrier permeable to said liquid, and at least two components soluble in said liquid, capable of migrating within the carrier when the carrier is wetted by said liquid, the components or parts thereof forming a coloured complex, which colour is not significantly altered or removed by a surplus of said liquid.
A method for the detection of leakage of a liquid, characterized in providing a carrier permeable to said liquid, said carrier comprising at least two components, capable of migrating within the carrier when the carrier is wetted by said liquid, the components or parts thereof forming a coloured complex, which colour is not significantly diluted or removed by a surplus of said liquid;
- affixing said carrier to a location where leakage can be expected;
- and observing said carrier for colour changes.
