How the PCM320 Pressure Transmitter Supports the LNG Industry

As the demand for clean, efficient energy grows, Liquefied Natural Gas (LNG) has become a key player in the global energy market. With its high energy density and low emissions, LNG is widely used in transportation, power generation, and industrial applications. But storing and transporting LNG involves significant engineering challenges—particularly when it comes to cryogenic pressure monitoring.

That’s where the PCM320 pressure transmitter comes in. Designed specifically for cryogenic and vacuuminsulated environments, the PCM320 provides accurate, reliable pressure measurement essential for safe and efficient LNG operations.

 What Is LNG and Why Pressure Monitoring Matters

LNG is natural gas cooled to 162°C, which reduces its volume by 600 times and transforms it into a liquid state for easy storage and transport. To maintain this ultracold condition, LNG is stored in vacuuminsulated tanks or transported via cryogenic tankers.

Inside these systems, pressure control is critical:

 1.Preventing tank overpressurization or vacuum failure

 2.Enabling controlled LNG flow during fueling and vaporization

 3.Supporting automated safety and monitoring systems

Accurate, stable pressure readings ensure that LNG stays within safe operating limits throughout the supply chain—from production to storage, transportation, and end use.

 Small form factor allows easy installation in compact systems

 ✅ Standard Signal Output

 Supports 4–20 mA, 0–10 V, and other industrial signal types

 Seamless integration with SCADA systems, PLCs, and data loggers

Where the PCM320 Is Used in the LNG Industry

The PCM320 has been widely adopted across the LNG value chain. Below are key applications where it delivers proven performance:

*LNG Storage Tanks

Monitors internal tank pressure in cryogenic storage systems at terminals, refineries, and industrial facilities.

*LNG Refueling Stations

Supports pressure control during LNG dispensing for trucks, ships, and buses, ensuring smooth, safe refueling.

*Cryogenic Transport Tankers

Used in mobile tankers to ensure stable pressure during LNG transportation, reducing safety risks and product loss.

*Vaporization and Gasification Stations

Provides pressure feedback during the regasification of LNG, helping regulate flow and maintain efficiency.

 Working with Capacitance Level Gauges

The PCM320 is often used in tandem with capacitance level gauges to provide a full picture of the LNG tank's status. While the level gauge measures the liquid volume, the PCM320 tracks pressure changes that could indicate operational or safety issues.
