Field of application
Using patented tunable diode laser spectroscopy (TDLAS) technology, the SS500 analyzer is an economical choice for measuring H2O concentration in natural gas without coming into physical contact with the stream. The result is a sensor that does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, or amines.
Natural gas quality measurements in production, storage, transportation, and distribution
Monitoring for natural gas pipelines, processing plants, compressor stations, gathering sites, and distribution quality
Suitable for use as a check-measurement device
Measurable ranges of up to 0.25 – 100 lb/mmscf (5 – 2110 ppmv)
Benefits
Economical real-time moisture measurements
Virtually maintenance-free
Reliable in harsh environments
Fast and accurate with no wet-up or dry-down delays
No contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans
NIST-traceable calibration with analog and serial outputs for remote monitoring
CSA certified for CSA Class 1, Division 2 or Class 1, Division 1
