Redefining Reliability in Harsh Process Conditions: How Jerguson® FlashProof™ Magnicator® Solved a Major Refinery’s Level Measurement Issues

In high-temperature process environments, accurate level measurement is critical—not only for operational efficiency, but also for the protection of assets, personnel, and uptime. A recent success story out of the UAE illustrates how Clark-Reliance’s Jerguson® FlashProof™ Magnicator® Magnetic Level Gages and SAS-16™ Snap-Action Switches are setting a new industry standard in reliability—especially in the demanding conditions often faced in the energy sector.

📍 The Challenge: Boiling Fluids and False Alarms

A UAE-based refinery was experiencing consistent issues with their traditional magnetic level gages and level switches. Their high-temperature columns caused internal boiling within the gage chamber, leading to inaccurate level readings and frequent false trips and alarms. In some cases, floats within the level indicators would sink, resulting in complete failure of the system—often within a month of installation.

These failures are common when there’s a significant temperature differential between the process fluid and the indicator chamber, causing flashing or vaporization. For operations where safety and precision are non-negotiable, these inconsistencies posed a major risk.

✅ The Solution: FlashProof™ Technology That Performs Under Pressure

To address this, the refinery upgraded to Jerguson® FlashProof™ Magnicator® Magnetic Level Gages, equipped with SAS-16™ Snap-Action Switches.

🔹 FlashProof™ Magnicator®

Engineered specifically for applications with boiling fluids and flashing vapors, the FlashProof™ design features:

• A 3″ Schedule 40 pipe that helps manage entrained gases by allowing them to escape safely
• Dual internal guide rods to maintain float alignment and ensure magnetic field proximity
• Enhanced float positioning for accurate, stable level readings

🔹 SAS-16™ Snap-Action Switch

Unlike conventional mechanical switches, the SAS-16 uses a tri-magnet system that enables:

• Positive snap-action switching without the need for springs or cams
• Magnetic repulsion-based actuation for highly reliable performance
• Consistent operation in extreme environments with minimal maintenance

🔧 Real Results: From Unreliable to Unshakable

Since switching to Jerguson’s FlashProof™ solution, the refinery has systematically replaced most of their previous magnetic level gages—from a well-known competitor—with Jerguson units. The result? Zero performance issues and vastly improved reliability across their systems.
