    II.2. Operating conditions The gas analyzer is equipped with an automatic monitoring system of parameters that have an influence on measurements. If at least one of these parameters is out of bounds, and might have a metrological impact on results, then the gas analyzer automatically prevents any measurement from being performed until operating conditions are stabilized.

  • Page 42: Smoke-Meter

    III. SMOKE-METER III.1. OPERATING PRINCIPLE In the composition of the exhaust gas emitted by diesel engines, the pollutant component is considered to be carbon in suspension. A polluting vehicle emits on acceleration a puff of gas that is darker (and thus more opaque) than a vehicle in good conditions. The partial flow opacimeter is used to give a measure of this phenomenon based on a given measure unit called K (m The principle of opacity measurement is the following: a beam of light (transmitter aimed at a receiver, with a constant distance between the two) is passed through a sample of gas.
