(Click to enlarge image) CO2 Process Analyzer: The petrochemical, gas processing, and gas pipeline industry has required an accurate and dependable, low maintenance and cost-effective Gas CO2 analyzer for quality and process control purposes. Analytical Systems International has met these requirements with their proven microprocessor based non dispersive infrared CO2 analyzer monitor. This method provides continuous on-line analysis. The process stream is regulated to 10 PSI. Then a precision flow meter regulates the sample flow to approximately 1.0 SCFH. Next, the sample is introduced to the specific infrared detection element that provides an output proportional to the concentration of carbon dioxide. This signal, from the CO2 analyzer, is digitized and analyzed by the advanced microprocessor and related software resulting in a line 4-20 MA output, relay alarms, and RS232. The LCD display and associated electronics provides the current reading, previous reading, cycle time, any alarm conditions, procedure prompts (i.e., calibration procedure), and failure indicators (local and remote capability).
