Cargo tanks on LNG carriers
Pressure, level and point level detection in Liquefied Natural Gas (LNG) applications
Process data
    Measuring task:
    
    Level and pressure measurement, point level detection
        Measuring point:
    
    Tank
        Measuring range up to:
    
    40 m
        Medium:
    
    Liquefied gas
        Process temperature:
    
    -20 … -162 °C
        Process pressure:
    
    0 … +5 bar 
        Special challenges:
    
    Extremely low temperatures, low dielectric constants, low density, different products, ship approvals, Ex zone
Application
Liquefied gas is transported in insulated cargo tanks on LNG carriers at temperatures of -162 °C. The instrumentation used must be specially designed for these extreme temperatures. Pressure, level and point level of LNG in the cargo tanks must be reliably measured for the transport.
