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 chambe

We recently tackled a unique challenge at a refinery in the Southeast United States with an application for magnetic level indicators, each spanning an impressive 300” center-to-center. The customer wanted to utilize the internal retention spring, but also wanted the ability to mate their process piping on the drain, as well as keep a standard side connected gage. This was necessary for a number of reasons, but the most prevalent being support. The customer has quite a few

In a Midwest U.S. refinery, Jacoby-Tarbox's Series 5005 Sight Windows are making waves with their robust design and high-temperature capabilities. These sight windows are equipped with quartz, offering exceptional durability in extreme conditions. One standout feature is the purge port , allowing operators to cool the front of the window using nitrogen or other gases. This protective mechanism shields the window from excessive heat, ensuring both safety and longevity in dema

Background A major refinery in California faced compliance challenges with the boilers in their hydrogen plant. The existing traditional ported gages were non-functional, leaving the facility in violation of the ASME Boiler Code. This posed both operational risks and regulatory concerns, necessitating immediate action to address the issue. Solution Our team, in collaboration with the local territory representative, conducted a comprehensive site survey to assess the plant’s r

Customer Challenge: A customer operating in a cryogenic environment relied on a prismatic glass gage to monitor liquid levels. However, ice frequently formed on the gage due to the extreme temperatures, completely obscuring the view (see righthand photo). To check the level, operators had to: Drain the liquid. Isolate the gage. Wait 3–4 hours for the ice to melt. Once reopened, the gage would only provide a clear reading for a few minutes before icing up again, causing signif

A lube oil manufacturer in Brazil faced long blending times, taking approximately 8 hours to mix lube oil with proprietary additives using mechanical mixers. This prolonged process limited production capacity and operational efficiency. Using AccuBlend Computational Fluid Dynamics (CFD) A Jacoby-Tarbox® Program™ , it was demonstrated that Tank Liquid Agitators (TLAs) offered a more efficient mixing solution. The analysis revealed that in-tank eductors could achieve the same b

The Problem: A major refinery in India faced operational challenges in their Refinery Off-Gas Cracker Plant for an Ethane Vapor application. The traditional magnetic level gage initially installed proved inadequate for the process due to the low specific gravity (SG) of 0.44. The gage's flags failed to rotate accurately, leading to incorrect level readings and frequent equipment malfunctions. The Jerguson Solution: We proposed and installed a Jerguson® Magnicator® Magnetic Le

DID YOU KNOW? Jacoby-Tarbox offers a full line of spray rings for installation directly against sight windows to direct secondary fluids (liquid or gas) against the window to remove debris. Standard Features: • Size Range: 2” through 10” • ASME Flange Class: 150, 300, 600 • “Ring” style centered by bolting • ¼” NPT Supply connection • Material: 316 SS • Maintains window rating • Compound angle radial and cross jets ​Optional Features: • Material: Corrosion resistant alloys •

PERFORMANCE AND RELIABILITY YOU EXPECT IN YOUR LEVEL TRANSMITTERS THE PROBLEM: Reliability issues with 'traditional' magnetrostrictive transmitters in terms of installation, setup, and connectivity. THE SOLUTION: With patent pending signal capture technology, the JMT™ Series Magnetostrictive Transmitter can be mounted on almost any chamber configuration without sacrificing reliability. The dual-entry enclosure allows for safe access to the HMI where information can be had wit

Utilizing eductors in wastewater and process water handling uses proven technology to maximize plant sustainability. Wastewater, often called process water, must conform to EPA regulations prior to returning it to the environment. Click here to read the full case study! Why Wastewater Handling Has Become a Bigger Conversation Chemical producers, refineries, and manufacturers - heavily regulated for gases and chemicals produced and added to the environment - are now being scru

We had Jerguson Product Manager - Magnetic Level Products, Robert Bolin, onsite at a major refinery in the Midwest US, giving a lunch & learn presentation on Jerguson Magnetic Level Products. Why We Do Lunch & Learns A lunch & learn puts real product expertise directly in front of the engineers, operators, and maintenance personnel who work with this equipment day to day - a different format than a webinar or a written article, since it allows direct questions and discussion

Check out our Jerguson® Magnicator® Magnetic Level Indicator installed on a skid for monitoring, measuring, and dispatching turbo jet fuel. This installation was for a skid manufacturer in Peru. The gages were inverted due to limited lower clearance - mounting them inverted allows operators to easily access the float from the top flange. How a Magnicator Actually Works The Magnicator level indicator connects to a process vessel. The chamber, or "column," contains a sealed flo

We have our first batch of 1" Threaded Bulls-Eye Sight Flow Indicators (Model # 100-ST) headed to a major refinery in the Midwest United States. This refinery has ordered 500 Sight Flow Indicators total, to be included on the drain lines and connections of their tanks, ensuring all product is out of the tanks after a chemical wash during their next turnaround. Why Drain Line Verification Matters During a Turnaround A refinery turnaround involves taking process units offline f

A fuels refinery in the Southern US contacted us regarding our in-tank eductor technology, Tank Liquid Agitators (TLAs). The tank at this refinery is used for crude oil received from a ship and then moved into the refinery for processing. Two Jobs, One Tank This application required the TLAs to do two things at once: suspend solids and mix the tank contents. Crude oil storage tanks commonly deal with basic sediment and water (BS&W) — heavier material that settles out of the o

We recently shipped three 4-section, glass series size 8, transparent close hookup series 20 gages (48TCH20) bridle assemblies with 67LE valves and illuminators to a major refinery in the Midwest. Continuing on our Low-E topic, these 67LE valves are low-emission certified to API 624, providing compliance with EPA standards (see our companion article on what API 624 testing actually involves). Understanding the Gage Designation The "48TCH20" designation packs several specifica

Power plants, chemical plants, and refineries have a large number of potential leak sources that can release harmful fugitive emissions (FEs) into the environment. This creates real risk on multiple fronts: environmental damage, exposure of plant personnel to harmful gases and vapors, and economic impacts from lost product. As a result, regulations are becoming increasingly strict, and many facilities are proactively requiring that any valves procured for future maintenance a

Many low-pressure package boilers use tubular glass gages as a means for monitoring level on their Low Water Cut Off/Pump Controllers. These boilers typically operate below 250 WSP (working steam pressure). It's a common setup — but tubular glass carries a risk that's often overlooked: it's susceptible to chipping or breaking, and as a result can be potentially unsafe even in these low-pressure steam applications. Why Low-Pressure Doesn't Mean Low-Risk There's a natural assum
