    4. Gas Cooler Peltier outlet element WARM Level COLD monitoring Gas inlet Condensate evacuation Exhaust gas with a temperature above the steam dew point (35 - 65 °C) is introduced into a long spiralling gas path with a surface coated metal body with good thermal conductivity. The gas radiates its heat to this metal body.

  • Page 11: Power Supply

    Used batteries can be brought to recycling stations or public waste disposal companies! The EN2-F is recommended to be powered by AC power when available. The analyzer can also be powered using the internal bat- tery for a while (6 V; 3.8 Ah). The battery should be recharged when the analyzer starts beeping or an alert message appears.

    8.2 Inserting the probe (continued) Perform the measurement in the core stream of the exhaust gas channel (probe placed in the hottest gas temperature area). A trend indication for T.Gas lets you know whether the temperature is in- creasing or decreasing so that you can find the core stream. As long as the display shows an up arrow, it means the probe tip is moving towards the core stream center.

    If the measurement values are stable, press the Save Button (num- ber 6) to transfer the values in the internal memory or F2 to print. 8.5. Printing Press F2 to print the values on the screen. To use the Printer button (number 6 on the keypad), you have to press the Save button (number 7 on the keypad) before pressing Measurement stored in the Printer button.

  • Page 25: Control

    13. Control The electrochemical sensors for gas analysis are submitted to a wearing process and do age. They alter their output values along the time depending on the gas concentration, the exposure time and the soiling grade of the sampled gas. The programme monitors the sen- sors and corrects drifts.

    PC programme (procedure similar to chapter „Load data“). 15. Delta-T Measurement (Option) With the ecom-EN2-F a difference temperature measurement is pos- sible. For measurements at pipings (e.g water-in and water-out of heating systems), special temperature sensors are needed, available from your authorised rbr agency.

  • Page 28: Maintenance Tips

    To secure the accuracy of your measuring instrument we recom- mend the annual check by an authorized ecom partner. In the case of strong demand (e.g. permanent several hours of measurement per day, rough conditions etc.) shorter intervals between checks should be selected - please contact your ecom partner.
  • Page 29 Prefilter The prefilter made of high-grade steel is within the condensate con- tainer. It should be cleaned when contamination (with warm water and dry). Unscrew condensate container and prefilter. Assemble after cleaning again in reverse order. Prefilter Sensors The sensors get calibrated with the reference gas fresh air by each switch-on.
  • Page 30 Probe and tubing Depending on the frequency of use, probe and tubing should be regularly cleaned in order to release particle deposits and to prevent early wearing due to corrosion. - Release the connections at the instrument and at the probe grip to free the tubing.

  • Page 34: Calibration Procedure

    19. Calibration Procedure For best results, the calibration gas concentration should be as close to the expected levels of emissions as possible. Because each sensor is linear through a nominal range, one calibration gas concentration can be used for a reasonably wide range of emission levels.
  • Page 35 19. Calibration Procedure (continued) You must check for air leaks before calibrating. Apply a gas with 0% O2 to check for air leaks (ECOM service dept. uses NO gas balanced in N2). Flow calibration gas for 3 minutes. Check that O2 reading is 0.0%.
