One practical application of this method is the monitoring of engine rooms on oceangoing tankers. In the event of leakage in one of the high-pressure lines feeding oil to the big diesels, extremely fine diesel oil mist is created. Because the mist is highly explosive, it is a matter of life and death to detect even tiny amounts quickly and to signal their presence.
The installation used for this purpose consists of a turbidimeter for detecting the scattered light produced by the tiny droplets, and a multiple sampling setup. The latter sends samples from 36 critical points in the engine room to the turbidimeter over distances up to 200 m.
