This outline is based on JJF 1015-2014 "measuring equipment type and universal norms" and JJF 1016-2014 "count Evaluation of the amount of equipment type outline guidelines for the preparation "Writing. Technical content of this outline the main reference JJG976-2010 "Transmission-type smoke meter", part reference ISO 11614.1999 (E) "reciprocating compression ignition engine measuring flue gas emissions Opacity and a light absorption coefficient of the instrument. " The outline for the first time to develop. Transmissive type smoke meter evaluation outline1 ScopeThis type of evaluation outline applies classification codes to 46,481,000 of Split ① transmissive smokemeter ② (hereinafter referred to as Smoke meter) of pattern evaluation. ① take style known as Split. There are corresponding full-flow opacimeter. ② also known as opacity meter, impervious photometer, opacimeter, light type smoke meter and so on. ③ also known as opacity. 2.

Φ --- dark passage full of luminous flux received on flue gas emissions time receivers, lm; Φ0 --- dark passage full of luminous flux received on time and clean air receivers, lm. 3.2 absorption ratio N absorptanceN③ The light emitted from the light source than the flux of the incident light flux absorbed by the dark smoke-filled channels. N = Φ0-Φ Φ0 × 100% = 1-τ (2) 3.3 effective optical path length L effectiveopticalpathlengthL From the light reaches the light receiver instrument light emitted by the dark smoke-filled channel length in m. press ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1482-2014_English be delivered?Answer: Upon your order, we will start to translate JJF 1482-2014_English as soon as possible, and keep you informed of the progress.
