Precisive® 5-282
Natural Gas, Calorific Value/Wobbe Index Monitor

photo - Precisive 5 Analyzer

The Precisive® 5-282 is designed specifically for on-line quality monitoring of natural gas products. It provides fast and accurate measurement of Calorific Value, Wobbe Index, Specific Gravity, and Gas Density along with compositional information, including CO2 in a single, compact analyzer. The analyzer is based on MKS' unique Tunable Filter Spectroscopy (TFS) platform which directly measures the component concentrations in the gas. Applications include fuel quality analysis for gas turbines and internal combustion engines, pipeline gas fiscal metering and natural gas quality measurement at LNG terminals.
