Exploring The Role Of Radar Level Gauges in LNG Cryogenic Storage Tanks

Liquefied natural gas cryogenic storage tank is a unique liquid storage equipment with the following salient features. First, it is in a cryogenic environment because LNG needs to be stored at extremely low temperatures. Secondly, storing liquefied natural gas requires maintaining a certain pressure, usually between 0.5 and 1.5MPa. Third, because LNG is flammable and explosive, measures need to be taken to isolate it from the outside world to ensure safety. For this reason, LNG cryogenic storage tanks usually adopt a double-shell structure, with a certain gap left between the inner and outer tanks to prevent liquid leakage. Because of the low temperature, high pressure and isolation characteristics of LNG, liquid level measuring instruments must have high precision, high reliability and anti-interference characteristics.

The tank radar level transmitter meets these requirements exactly. First of all, it has good low temperature resistance and can work normally in extremely low temperature environments below -200°C. Secondly, Liquefied natural gas radar level gauge has high accuracy and can achieve millimeter-level liquid level measurement. In addition, it is not affected by the medium and environment, can accurately measure liquid level, has high reliability and safety, works stably for a long time, is not prone to failure, and will not cause explosions, thus ensuring the safety of the storage tank.

In general, the radar level meter has the characteristics of low temperature resistance, high accuracy, not affected by the medium, high reliability and high safety, so it has become a choice for liquid level measurement of LNG storage tanks. However, it should be noted that when measuring LNG cryogenic storage tanks, it is necessary to select an appropriate tank radar level transmitter model suitable for different liquid media and working environments, correctly determine its installation location, and perform regular maintenance such as inspection, cleaning, and calibration. Maintenance work to ensure its normal operation and long-term stability.
