Sdt

SDT is a system based on ultrasonic principles, with own software, able to translate ultrasonic pulses into drawings and diagrams. it can detect  holes and critical points inside the tank, certifying the status of sanity of tank. By applying a small depression into the tank, each leakage will cause a US noise detectable inside the tank. The system is able to check and evaluate leakage up to 0.002 litre/hour.
