A new product bulletin is available that describes Biospherics' self-cleaning "Oilarm" oil-in-water bilge alarm. Factory set to trigger a set of Form C contacts at 15 ppm, the threshold is internally adjustable from 0 to 100 ppm of oil in water.
The on-line device samples the overboard discharge seven times per minute without the use of sampling lines, automatically cleaning the optical surface with each stroke of the sampling piston. Oilarm is the newest of a series of self-cleaning instruments manufactured by Biospherics Incorporated, Lanham, Md.
