Gas Calorimeters and Heating Value Transmitters

Cosa has supplied the US industry with gas calorimeters (Wobbe Index Meters, Heating Value Transmitters) for over 30 years. Our expertise in BTU measurement covers a wide range of applications, including turbine control, gas blending, combustion control, flare stack monitoring and custody transfer in natural gas.

Today's product range represents the most advanced technology available in this field. With Heating Value Gas Chromatograph Field Transmitters and Combustion Calorimeters, we can fulfill the widest range of applications.

Combustion Calorimeters (Wobbe Index / Wobbe Meter)
The NEW Fast Response BTU Analyzer

The NEW COSA 9610TM Wobbe Meter provides a fast and accurate measurement of Wobbe Index, Heating Value and Combustion Air Requirement Index (CARI).

New updates to the COSA 9610TM Wobbe Meter have expanded capabilities that include total sulfur measurement, data storage of measured values and remote access, higher sample system temperatures, and more stream switching capabilities than other calorimeters or other Wobbe Meters.

The COSA 9610TM Wobbe Index Meter is a flameless combustion calorimeter that can provide Wobbe, BTU, MJ, Kcal, Specific Gravity / Relative Density, CARI, and Total Sulfur measurements for Flare Gas, Hydrogen, Biogas, Turbine Control, Air Blending, Process and Natural Gas Applications.
