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.

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.

Models C24/C25, boiler, and water column liquid level switches are single- or multi-switch units that offer versatility and reliable operation in a variety of applications. Available with up to three switch mechanisms for level alarm, control, and shutdown functions, the boiler and water column controls are designed for use in steam boiler applications while the Models C24 and C25 are for general use.

Series 3 ASME B31.1 float-actuated level switches are designed, built, and certified to the requirements of ASME B31.1 power piping codes. They are ideal for critical alarm set points in clean liquid applications.

Series 3 ASME B31.3 float and displacer-actuated level switches are designed, built, and certified to the requirements of ASME B31.3 power piping code requirements. They are ideal for critical alarm set points in clean liquid applications.

Series 3 NACE float and displacer-actuated level switches are designed, built and certified to meet NACE MRO175 and MRO103 requirements. They are ideal for alarm and control set points in sour liquid applications.

All welding is performed by qualified welders and per procedures required by the ASME Boiler Pressure Vessel Code Sec. IX. Carbon steel pressure boundary parts are post weld stress relieved. All welds and heat-affected zones are hardness tested to ensure compliance with NACE maximum hardness requirements.

Series B73 and series 75 external cage type level switches are completely self-contained units designed for side mounting to a tank or vessel with threaded, socket weld or flanged pipe connections. These float-actuated controls have proven their reliability in process control for decades.
