Complete LNG Tank Gauging Package

JOYO provides a full turnkey LNG Tank Gauging System designed for accurate monitoring and safe operation of LNG storage tanks. The complete package includes:

LTD gauge (Level + Temperature + Density)
Primary and secondary level gauges
Primary and secondary multi-point thermometers (MPT)
High-high (HiHi) alarm level gauge
LNG rollover prediction and tank management software

Basic Information

JOYO successfully developed and deployed the first Made-in-China LNG level gauge, including the country’s first LTD gauge and LNG monitoring system. This advanced solution is now operating in LNG storage tanks across the Chinese market.

The system delivers highly reliable measurements and comprehensive tank monitoring through redundant instrumentation and intelligent software integration.

1. LTD Gauge

The BJLM-80L LTD Tank Gauge consists of:

Gauge body MNF smart displacer

Both the density sensor and temperature sensor are fully integrated inside the MNF displacer.
The BJLM-80L is specially designed for cryogenic bulk storage applications, providing combined Level, Temperature, and Density (LTD) measurements in a single instrument. This makes it ideal for LNG tank gauging, where detailed and accurate profiling is critical.

Key Highlights:

Multi-function integrated measurement
Precise LTD profile monitoring
Built-in LCD display for real-time process and diagnostic data

2. LNG Tank Gauging System (TGS)

A typical LNG tank gauging solution includes:

Redundant primary and secondary level gauges
Redundant primary and secondary thermometers
An additional LTD gauge for detailed profiling
Radar or servo gauge used as the HiHi alarm instrument

All measurement data is connected to a PC-based monitoring platform, where the LNG Manager & Rollover Predictor software continuously operates to ensure system safety and operational efficiency.

The system is fully configurable, redundant, and can be directly integrated into the site’s upper-level DCS if required.
