Paramagnetic and magnetopneumatic O2 detection analyzers.

§ 1065.280 Paramagnetic and magnetopneumatic O2 detection analyzers.

(a) Application. You may use a paramagnetic detection (PMD) or magnetopneumatic detection (MPD) analyzer to measure O2 concentration in raw or diluted exhaust for batch or continuous sampling. You may use good engineering judgment to develop calculations that use O2 measurements with a chemical balance of fuel, DEF, intake air, and exhaust to calculate exhaust flow rate.
