Since TTK cables / probes are product sensing, our technology is for external leak detection. TTK sensing system is capable of detecting light / heavy refined products, crude oils, lubricant / dielectric oils, solvents and petrochemical compounds (water insoluble) such as aromatics, MTBE / ETBE amongst others. Early detection with accurate location of oil leaks provided by the system allows reacting at a very early stage thus preventing environmental damage and safety hazards. TTK sensors do not require any calibration or whatsoever maintenance and are reusable – they can hence be easily tested on site, in real conditions. Since TTK sensors are addressable (thanks to microprocessor embedded in each cable / probe), the overall system is true multi-leak: independent alarms, reliable localization of each single leak.
