Alarm and Data Management System – 9205EMS

• 9205 – Generic Network Software Package• Supports multiple communications

protocols• Real Time Display of Measured Values• Generates and Logs Alarms• Accumulates Stack Discharge (Daily, Weekly,

Monthly, Annual)• Database of results (History)• Automated Reports in Word format

Stack Flow Measurement

• Pitot tube averages flow across duct– Stainless steel– Proper placement important

• DP-2001 Differential Pressure– Calibrated for correct pressure range

• 4 to 20 mA Signal to CMS-Pet– Standard Ethernet cable used

Stack Sampling Systems

• Shrouded probes (1” and 1.5”)• Meet ANSI N13.1-1999• Licensed by Texas A&M• NQA-1 Quality Assurance• Seismic analysis performed• Design capability for new

applications

• Gas sampling probes• Various mounting flanges used

System Use With Air Cannons

• Flow rates cannot be accurately measured after the air cannon because of turbulence

• Measuring the concentration prior to the air cannon offers better statistics for lower concentrations

• Software can add in the additional air allowing it to report proper release concentration results

• Monitoring before the air cannon allows proper measurement and reporting of activity releases
