3098 Gas Specific Gravity Meter
Micro Motion 3098 gas specific gravity meters
The 3098 gas specific gravity meter provides all the benefits of highly accurate, continuous on-line
measurements of gas relative density and specific gravity.
About the 3098
The 3098 is the latest development in a product line
that is well established as the industry standard for
gas specific gravity meters. It is the only product that
offers continuous on-line measurements as well as
the following benefits:
• highest accuracy and resolution available today
• fast, dynamic response to process conditions
• self compensation for gas compressibility
• custody transfer approval
Because the 3098 is calibrated in the field, it
provides the additional benefits of user
customization and the flexibility to output multiple
parameters to suit your application needs. The 3098
can measure gas specific gravity, gas relative
density, and combustion energy content (such as
Wobbe Index).
The 3098 is available in the following configurations:
• with ATEX/IECEx or CSA approvals
• installed in a small or large enclosure
• with an integral sample conditioning system
The sample conditioning system preconditions the
measurement gas from pipeline pressures and
temperatures to those required by the 3098. This
option reduces installation complexity and simplifies
commissioning.
Advantages
• Better control of product quality
• Faster response to changing conditions
• Reduced waste
• Improved safety
• Greater profitability
• Overcomes the disadvantages of traditional
sampling techniques
Typical applications
• Specific gravity measurement
• Relative density measurement
• Calorific value using AGA 5
