2. Analyzer description
2.1. Introduction
The main task of the NOVAcompact gas analyzer is in supporting the following applications:
• Precise control- and adjustment measurements for Gas- , oil or wood fired burners
• Flue gas measurement according to 1. BImSchV and KÜO (German regulations)
This analyzer can be equipped with additional options and/or additional accessories to full fill
multiple other measuring tasks such as
• Measurements at CHP's (cogeneration heat and power engines) with CO-sensor protection
by means of a Purafil filter
• Proof of sufficient combustion air supply „4 Pa – test“
• Anemometer (Option Flow velocity, using either a Pitot tube or a vane)
• Differential measurements of pressure and temperature
• Mobile Gas detector (Option HC-sniffer)
• Leak testing device (Option external pressure sensor)
The multiple options and multiple connections possibilities of external sensors often replaces
the need of additional measuring equipment(s). Ask our sales reps. for available options and
accessories or check out our MRU website.
2.2. Gas flow diagram
In combination with the sample gas probe, analyzer filtered off a partial volume of sample gas
from the combustion channel, and analyzes it by means of electrochemical sensors on its
ingredients.
Pressure (draft) and temperature are measured by the design of the exhaust probe directly at
the probe tip.
