Cargo tanks on LNG carriers
Pressure, level and point level detection in Liquefied Natural Gas (LNG) applications
Pressure, level and point level detection in Liquid 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.
