Data Acquisition & Management Systems:

A Small District’s Perspective

(or how I became a kid again at 60)

NSCAPCD Monitoring Network

• 3 PM10 Aerometric Sites w/ MetOne BAM1020-965’s and Agilaire ESC 8832’s

• 1 Ozone Aerometric Site w/ Redundant Teledyne API 400E Ozone Analyzers and Agilaire ESC 8832’s

• 3 DSL Lines w/ CISCO VPN Firewalls• 1 Satellite Link w/ CISCO VPN Firewall• Agilaire AirVision© Software on a Virtual Server w/

Separate SQL Database

Agilaire AirVision Data Acquisition and Mgt Software

AirVision Suite (Version 2.4.161) with:– BAM Direct Poll Option (Digital)– File Import Configuration Option – ADVP (Advanced Data Validation Program) Option– Parameter Equation Math Pack Option– Precision & Accuracy Reports Option

Why Sample Digitally?

• Avoid DAC/ADC Conversion Errors• Data Reliability • Enhanced Instrument Diagnostic Information
