The Wobbe Index is actually the correct representation of the heating value of natural gas arriving, from the gas line, at the orifice where a burner is located.
It is not simply the BTU per cubic foot but rather the BTU per cubic foot divided by the square root of the specific gravity.
The COSA 9610™ is one of the latest instruments from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index).
The Cosa 9750 is a fast response Zero Emission calorimeter for the on-line monitoring of Wobbe Index (WI), Combustion Air Requirement Index (CARI) and Heating Value (HV). The COSA 9750 is based on the Residual Oxygen Method (ROM), thus avoiding the use of a flame.
COSA Xentaur introduces one of the first commercially available portable Optical Gas Calorimeters. After extensive development work, this instrument proudes the fastest spot check response in the industry; T90=15 seconds for Natural Gas and LPG.
