If your equipment requires maintenance in Italy: BEFORE YOU SHIP THE INSTRUMENT BACK TO ITALY REMEMBER: !When you ask your shipping agent to send the instrument to Italy check that on the Air Waybill the Airport of destination is PISA. Any other airport of destination creates a lot of problems in delivering the items (delay, costs, custom problems etc.) !Check that the Company your shipping agent chooses lands in Galileo Galilei Airport in Pisa.

WEST Systems www.westsystems.com PAGE 1.2 Safety information ! ! Carbon dioxide is a TOXIC GAS, Carbon dioxide is colorless, odorless, tastless and is heavier than air. Air concentration higher than 5000 ppm can cause dizziness, shortness of breath, rapid pulse. Higher concentrations of carbon dioxide can be lethal. Diffuse carbon dioxide fluxes are normally related to anomalous carbon dioxide air concentration.

About installation Before to start the installation of the FluxStation is better to install the Master center telemetry systems and to setup the Scada software suite on the computer. 1.1 PAGE Hints The onfield installation is described on chapter 2.

General discussion The subjects regarding calibration of your instrument for the measurement of diffuse flux will be discussed in this chapter. 8.1 PAGE Calibrations As explained previously the flux measurement is proportional to the slope of the concentration curve versus time. The proportionality factor depends on the volume/surface ratio of the accumulation chamber used for the measurement, as well as, the barometric pressure and air temperature at the moment of making the measurement.
PAGE 64
PAGE 8.2 Calibration of Drager IR CO2 When you need to calibrate the Drager The Drager is a quite stable detector, the thermal stabilization features allows the instrument to maintain it calibration for long periods. The calibration is necessary only when there is a drastical change in the barometric pressure. What you need to calibrate the Drager ! ! A cylinder of nitrogen or synthetic UPP Air, or a SODA LIME trap or a DRAGER PIPE to trap the carbon dioxide.

This calibration procedure can be necessary if the reading odf CO2 concentration on the FluxStation and the reading of the Drager are different. Normally there is a small difference between the DRAGER and FluxStation; This is due : !to the resolution of the display of Drager: +/- 10 ppm and +/- 100 ppm if the full scale is more than 10000 ppm; ! to the analog to digital conversion; ! to the leak of linearity of DRAGER in some ranges.

Calibration of the flux meter Fluxmeter calibration As the computation of flux is a function of the gradient of concentration vs. time, barometric pressure, air temperature and the the accumulation chamber volume / surface ratio, calibration of the instrument depends only on the detector calibration.

8.11 PAGE Calibration of the flux meter Fluxmeter calibration For fluxes between 300 moles/(m2day) and 700 moles/ (m2day) the injected flux is controlled by means of a mechanical flow reducer and measured using a bubble flowmeter (Accuracy 3%) before and after the flux measurement with Two series of measure were performed for flux of 300 moles/(m2day) to evaluate the coherence between the two different methods of flow measurement.
