Direct Contaminant Measurement

Data collected from Liquid Aerosol Measurement is often used to determine if costly aerosol removing filtration equipment is actually required in a system.
Liquid contamination is often present in natural gas pipelines as an aerosol. Liquid aerosols, although small in mass, can build up over time and have damaging effects on downstream equipment. The Direct Contaminant Measurement (DCM) high pressure laser particle counter is used to measure the size distribution and content of aerosols in a pipeline. In order to ensure that a representative amount of contaminant aerosol is measured, the gas is sampled isokinetically, meaning that the gas velocity through the DCM will equal that of the pipeline. The pipeline pressure and temperature are also maintained during DCM measurement as not to vaporize or condense additional aerosols while testing.
