An LNG tank gauging system is a critical component of liquefied natural gas (LNG) storage and transportation infrastructure. It is used to monitor and manage the level of LNG in storage tanks, ensuring safe and efficient operations.
Key components of an LNG tank gauging system include:
- Level Sensors: Various types of sensors are used to measure the level of LNG in the tank. Common types include radar, servo, and guided wave radar sensors.
- Temperature Sensors: Temperature sensors are used to measure the temperature of the LNG, which is important for accurate volume calculations due to LNG’s temperature-dependent density.
- Pressure Sensors: Pressure sensors are used to measure the pressure inside the tank, which is important for safety and for calculating the volume of LNG based on pressure.
- Control System: The control system processes sensor data and calculates the volume of LNG in the tank. It also controls the operation of valves and pumps to maintain the desired level of LNG in the tank.
- Communication System: The tank gauging system is often connected to a central control room or SCADA system for remote monitoring and control.
- Safety Features: LNG tank gauging systems include safety features such as overfill protection and leak detection to ensure safe operation of the storage facility.
The LNG tank gauging system plays a crucial role in ensuring the safety, efficiency, and profitability of LNG storage and transportation operations.
