Blending operations

Mixing finished gasoline requires level monitoring of blending stocks, in-line blending, additive storage, dilution systems and injection systems. Blend stocks are straight-run gasoline, alkylate, reformate, benzene, toluene and xylene. Additives include octane boosters, metal deactivators, anti-oxidant and knock agents, gum and rust inhibitors, and detergents.

Challenge

Level is normally measured only for inventory control and, in some cases, custody transfer. The precision of level indication that is required varies. If level is used only for internal inventory control, a less accurate measurement can be used. If level is used for custody transfer, highly accurate measurements are required.

Atlas™ magnetic level indicator

The AtlasTM is our standard, high performance magnetic level indicator. The ATLAS is a single-chamber design, with either 2", 2.5", or 3" chamber diameter, as required by the application. There are twelve basic configuration styles, including top mount models.

ATLAS magnetic level indicators are produced in a wide range of materials of construction, including exotic alloys and plastics. We also offers one of the most complete selections of process connection types and sizes for level measurement.

The ATLAS unit may be equipped with a variety of level transmitters and switches, as well as flag and shuttle indicators with or without stainless steel scales. This enables the ATLAS magnetic level indicator to be a complete level and monitoring control.

Aurora® magnetic level indicator

The Aurora® combines the operating system of a conventional float-based magnetic level indicator (MLI) with the leading-edge Eclipse® guided wave radar transmitter developed for level measurement applications. The result is true level-measurement redundancy in a single-chamber design.

Using a 3" or 4" chamber to house both the Eclipse probe and the MLI float, these devices operate seamlessly to provide continuous electronic guided wave radar measurement and visual indication. There are six basic configuration styles and more than 15 material selections for the Aurora magnetic level indicator.

For the first time ever, the ability to accurately and repeatedly measure ultra low dielectric media, high temperature/high pressure process conditions, and media with shifting and changing dielectric values can be accomplished with Aurora.

Gemini^™ magnetic level indicator

The Gemini MLI offers innovative level measurement in a special twin-chamber design. A magnetic float and high-visibility indicator in the primary chamber operate indepently of the Eclipse^® Guided Wave Radar transmitter in the secondary chamber. This use of two differing technologies adds a layer of redundancy similar to the Aurora model.

Gemini's magnetic indicator chamber can be equipped with switches and additional transmitters for expanded capability. Isolation vales are also easily implemented between both chambers to provided flexibility while fulfilling periodic maintenance procedures.
