Cargo tanks on LNG carriers

LevelPoint LevelPressure
Cargo tanks on LNG carriers

Overview

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.

Operating Conditions

Measuring Task
Level and pressure measurement, point level detection
Measuring Point
Tank
Medium
Liquefied gas
Measuring Range
40 m
Temperature
-20 … -162 °C
Pressure
0 … +5 bar

Challenges

  • Extremely low temperatures, low dielectric constants, low density, different products, ship approvals, Ex zone
  • 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.

Benefits

  • Reliable: Reliable and safe measurement in all media
  • Cost effective: Full utilization of the tank volume
  • User friendly: Simple planning and commissioning

VEGA Inventory System

Inventory System

VEGA Inventory System (VIS) is a web-based software for real-time data acquisition, visualization, and logistics management of inventory levels in storage tanks and silos. Companies can manage their inventories proactively, ensuring greater flexibility in delivery schedules, expanding optimization options, and reducing stock discrepancies. Precise, real-time visualization of stocks allows deviations to be quickly identified, minimizing financial impact. The system combines reliable VEGA measurement technology for liquids and bulk solids with secure cloud-based or on-premises software, providing the basis for intelligent and strategic decisions for optimal inventory management. VIS supports both internal inventory monitoring and Vendor Managed Inventory (VMI) applications, where suppliers manage customer stock replenishment using real-time level data.

  • Real-time inventory monitoring across all connected storage locations via web browser or mobile app
  • Four visualization modes — Chart, Graphic, Map, and Trend — for comprehensive stock visibility
  • Color-coded traffic light status system (green/yellow/red) for instant stock level assessment
