Calorimetry Measuring Devices (CWD)

The CWD2005 device series (Calorimetry, Wobbe-Index und Specific Density) comprises versions of combustion calorimeters for direct and continuous determination of gas quality from the following measurands and operands:

• Wobbe-index
• Specific density
• Heating and combustion values
• Combustion Air Requirement (CARI) and air requirement, with integrated gas analysis
• Energy quantity, with expanded system EMS2005.

The Wobbe index and specific density are measured, and the heating value and combustion value are calculated from these measurements.

When components for gas analysis are added to the CWD2005, the air requirement, or CARI, can also be determined from the analysed gas composition.

The operating principle of the CWD enables all combustible gas components to be detected, which allows it to be used even for gases with rapidly changing gas composition.

This measurement unit is – in a second step – configured as a complete device system-solution with enclosures for in- and outdoor areas or even EX-areas. It is available with or without gas cooler or measuring point switching.

The modular design concept leads to variable specifications for intended applications of the INCA devices.

The devices of the series INCA1000 and INCA3000 do overlap in their application possibilities. The cost and size-related benefit is up to INCA1000 whereas the INCA3000 offers a greater variety in performance and possibilities.
