Natural gas demand can fluctuate significantly throughout the year and even within a single day. During periods of peak consumption, such as extreme winter cold or summer heat waves, utility providers must ensure a stable and reliable gas supply to meet customer demand. One of the most effective solutions is the use of LNG peak shaving facilities, which store liquefied natural gas (LNG) during periods of low demand and vaporize it for distribution during demand surges.
At the heart of these facilities lies the LNG tank gauging system, a critical technology that provides accurate inventory measurement, real-time monitoring, and operational safety. By delivering precise data on LNG levels, temperature, density, and volume, tank gauging systems enable operators to optimize storage management and ensure uninterrupted energy supply.
Enhancing Safety in Peak Shaving Facilities
Overfill Prevention
Overfilling LNG storage tanks can create serious operational and safety hazards.
Tank gauging systems support:
- High-level alarms
- Independent overfill protection systems
