Solving Challenging High-Temperature Applications in the UAE

A refinery in the UAE faced ongoing challenges with their Magnetic Level Gages and associated Level Switches. The high-temperature process within their columns caused boiling inside the gages, leading to unreliable readings and frequent false trips and alarms.
Boiling fluids can cause the float to sink in a traditional level indicator. This situation is common when there are substantial temperature differences between the fluid in a vessel and the fluid in an indicator chamber. Recognizing the critical nature of their application, we provided a solution with our Jerguson® FlashProof ™ Magnicator® Magnetic Level Gages equipped with SAS-16 switches. Unlike their previous gages, which failed within a month, the Jerguson Solution performed flawlessly over the long term.
Jerguson® FlashProof ™ Magnicator® - The Jerguson FlashProof design addresses two potential problems that may occur with standard level indicators: boiling fluids and flashing vapors. By employing a larger 3″ Schedule 40 pipe and two internal guide rods, entrained gases that build up under the float can harmlessly escape. The float is held to one side of the chamber to insure an optimized magnetic field in close proximity to the indicator, transmitter or switches. This provides an accurate float level and indicator reading.
SAS-16™ Snap-Action Switch - The switch mechanism is based on a unique Jerguson tri-magnet design where the snap action is accomplished by the utilization of magnetic repulsion. The magnet mounted in the float causes the secondary magnet to rotate as it passes up and down. The switch magnet is repelled by the secondary and snaps to the opposite side. This causes the cradle to pivot, moving the push rod which operates the switch contacts. The result is positive snap action interlock switching – no springs…no cams…no problems.
The refinery has since replaced the majority of their existing Magnetic Level Gages from a reputed manufacturer with Jerguson’s FlashProof Magnicator gages. Every unit is now operating without any issues, delivering the dependable performance our customers come to expect from Jerguson and Clark-Reliance.
