Application Note
SpectraSensors SS1000 Portable is a light weight, easy to handle, battery-powered H2O analyzer, used to verify measurements and for spotchecking when other methods provide questionable results.
In natural gas pipeline applications, poor quality measurement results are extremely costly. Additional processing or dehydration costs, upset conditions, shut-ins and inconsistent process results may be caused by sensors that do not perform properly. The SS1000 reveals poorly performing sensors, pinpoints high moisture and can be used as a standard for measurement validation.
Rapid Response Time The SS1000 allows for fast, simple operation. The analyzer’s laser and detector take measurements 4 times per second and average the results. These real-time measurements are not hampered by wetup (absorption) or dry-down desorption) as with surfaced-based sensors.
Reliable Using state-of-the-art laser technology developed by NASA, the SS1000 analyzer is more reliable, with greater repeatability than surface based sensors and is not subject to the interpretation errors of a chilled mirror.
No Interference As with all SpectraSensors analyzers, the SS1000 combines a patented laser with control electronics and “smart” software. The analyzer’s sensor heads are not subjected to corrosives or contaminants in the gas because the sensor is isolated from the sample gas stream.
The result is an analyzer which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans.
Payback The SS1000 very quickly pays for itself eliminating the cost of consumables, extra sensor heads, factory calibrations and labor and overhead associated with excessive maintenance. Expensive problems caused by unreliable gas measurements such as added processing steps and poor gas quality can be eliminated.
