Environment Leak Detection
Leaks from your above and underground storage tanks can mean a direct loss of revenue.
They can also lead to contamination of soil and water courses, leading to punitive action from environmental authorities and damaging the reputation of your company.
Leak detection services from SGS bring you a quantitative tank leak detection service which removes the need to enter the tank, saving you time and money and minimizing the risk to personnel.
How the SGS-MTC leak detection system works
Developed by Mass Technology Corporation (MTC) and operated under exclusive license throughout Europe by SGS, the system enables the quantification of any leakage by monitoring the mass of liquid in a tank over a period of time. The liquid mass is derived from the head pressure at the bottom of the tank, which is measured using a differential pressure transmitter located outside the tank and monitored by a PLC. The pressure head at the base of the tank is transferred to the transmitter using a nitrogen bubbler system.
Benefits of the SGS-MTC tank leak detection system
Used as part of a risk-based maintenance program, this third-party evaluated system can remove the need for hazardous and costly entry to a tank. The versatility of the SGS-MTC system allows it to benefit many scenarios you may encounter. Examples include identifying leak origins, qualifying the findings of hydrotests and strengthening current storage tank inspection regimes.
