The rapid response of the SG901 ensures effective burner, furnace and flare gas monitoring and control. It is recommended in applications where specific gravity (SG) or molecular weight (MW) can be used to infer density elsewhere in the plant and where the gas is dirty or wet and requires filtering prior to the measurement. The SG901 is available in three configurations: a basic system, a dry gas system and a wet gas system. It comprises of a Thermo Scientific™ FD900 gas density assembly, temperature element and flow control valve. Built to endure harsh environments, the SG901 requires minimal maintenance and on-site calibration is not necessary.

Features:
  • User-selectable reference conditions
  • Integral sample conditioning
  • Options to suit dry or wet gas applications
  • Hazardous area use
  • Rugged construction for harsh environments
  • No on-site calibration required
Compatible with:
  • Thermo Scientific™ FD900, ID900 and PD900 Gas Density Meters
Recommended for:
  • Gas blending control
  • Standard volume flow control
  • Refinery fuel gas monitoring (CV estimate)
  • Oven/furnace gas monitoring (CV estimate)
  • Flare control systems (MW monitoring)
