Introduction
In the natural gas industry, pressure control is not just about measurement—it is directly linked to safety, reliability, and operational efficiency. Facilities handling large volumes of gas must ensure that pressure is monitored accurately at every stage of the process.
This application note highlights how the UE One Series pressure switch from United Electric Controls helped a major European gas storage operator upgrade from conventional mechanical switches to a smarter and more reliable solution.
Understanding the Process Environment
Natural gas storage involves injecting gas into underground reservoirs and withdrawing it when demand rises. While this sounds straightforward, the actual process is complex and includes multiple pressure-critical stages.
The journey of gas typically includes suction from pipelines, compression, dehydration treatment, and final delivery through collector systems. At each of these points, pressure must be continuously monitored to avoid unsafe conditions or operational disruptions.
Because of this, pressure switches are installed across the system—from compressor suction and discharge lines to treatment columns and delivery collectors. Any inconsistency in pressure monitoring can lead to shutdowns, inefficiencies, or even safety risks.
The Challenge with Conventional Systems
For many years, the operator relied on mechanical pressure switches. While these devices were robust, they began to show limitations under modern operating conditions.
One of the primary concerns was set point instability, especially under varying temperature conditions. This created uncertainty in switching performance, which is critical in safety-related applications.
Another major drawback was the lack of visibility. Mechanical switches do not provide any indication of process pressure or switch status, making it difficult for maintenance teams to verify whether the system is operating correctly.
Over time, these limitations led to increased maintenance efforts and the risk of false trips. Considering the scale of operation handling nearly 16 billion cubic meters of natural gas the company recognized the need for a more advanced and reliable solution.
The UE One Series Solution
To address these challenges, the operator evaluated the UE One Series pressure switch (Model: 1XSWLL) over a period of three years. The goal was to find a solution that could improve reliability without requiring major system modifications.
The selected solution was implemented in a 2 out of 3 (2oo3) voting logic configuration at the gas delivery collector.
In this setup, three switches are installed, and at least two must agree before triggering a shutdown. This approach significantly reduces nuisance trips while maintaining high safety integrity.
What made the transition easier was the fact that the One Series operates on the same wiring and control logic as traditional mechanical switches. This allowed the upgrade to be carried out without major changes to the existing system.
Performance Improvements Observed
After implementation, the benefits of switching to the UE One Series pressure switch became evident in daily operations.
1. Stable and Reliable Switching
The electronic design ensures consistent set point accuracy, even under fluctuating temperature conditions. This directly reduced false trips and improved process stability.
2. Improved Process Visibility
The built-in digital display allows operators to quickly check pressure values and switch status, eliminating guesswork and manual verification.
3. Faster Troubleshooting
With self-diagnostic capabilities, maintenance teams can identify faults much more quickly. This reduces downtime and improves overall maintenance efficiency.
4. Cost-Effective Upgrade Path
Since the device works with existing wiring and control schemes, the upgrade required minimal investment while delivering significant performance gains.
Why This Upgrade Matters
This application clearly reflects a broader shift happening across the industry. Traditional mechanical devices, while reliable in the past, are increasingly being replaced by smart electronic instruments that offer better accuracy, diagnostics, and usability.
In critical applications such as natural gas storage, even small improvements in pressure monitoring can lead to major gains in safety and operational efficiency. The UE One Series pressure switch demonstrates how modern instrumentation can enhance performance without adding complexity.
Our Recommendation
For applications involving compressor stations, gas treatment systems, and delivery networks, SWME recommends the UE One Series pressure switch (Model: 1XSWLL) as a reliable and future-ready solution.
Final Words
Upgrading to the UE One Series pressure switch is not just about replacing a device—it’s about improving the entire pressure monitoring philosophy of a plant.
In high-demand industries like natural gas storage, smarter instrumentation is no longer optional but it’s essential for safe and efficient operations.
