- Description
- Methane Analyzer System for Eddy Covariance measurements: The system must include Sample intake, Dryer, pump, tubing and fittings, and Analyzer in enclosure suitable for deployment at outdoor field site. The system must be compatible with an existing eddy covariance system that includes: LI7500 H2O/CO2 Analyzer (Li-Cor instruments, Lincoln NB) CSAT3 Sonic Anemometer (Campbell Scientific, Logan UT.) CR5000 datalogger (Campbell Scientific, Logan UT.) The system must also include a program for theCR5000 that incorporated the methane measurements with the existing eddy covariance measurements The vendor must be able to provide references for customers using equipment for eddy covariance field measurements. The system must be designed for Eddy Covariance: pump, dryer, sampling intake, and tubing sized for the proper flow and system frequency response. The equipment needs to be rugged and designed to be deployed in the field in a standard enclosure. The equipment and method needs to be tested in previous experiments and shown to have worked by indication of published results in the peer-reviewed literature. Specifications: All equipment must operate over a ambient temperature range of -25 to 50 degrees C Pump: Length: 44.2 cm (17.4 in) Width: 29.2 cm (11.5 in) Height: 26.9 cm (10.6 in) Weight: 19 kg (42 lbs) Capacity: 6 actual liters/sec @ 50 mbar Power: 950 W Dryer: Must include all fittings and hardware for mounting to tower Pressure drop (at STP) 5 mbar/(l/min) Flow Rate for -15 C dew point 16 l/min Internal volume 80 ml Purge Flow Meter Range 0 to 10 l/min Sample Flow Range 0 to 40 l/min Analyzer: Half Power Frequency Response: 3 Hz or better CH4 Measurement: 10 Hz Noise: 7 ppbv 30 Minute Gradient Resolution 140 pptv Physical Specifications Length: 211 cm (83 in) Width: 47 cm(18.5 in) Height: 55 cm (21.5 in) Weight: 74.5 kg (164 lb) Power Requirements Analyzer: 90 to 264 Vac, 47 to 63 Hz ,50 W (max) 30 W (typ) Heater: 90 to 264 Vac, 47 to 63 Hz, 150 W (max)
