Detection of oil in or on water

The properties of oil and water are sufficiently different to make distinguishing them relatively easy. Here we explore some of the state-of-the-art sensors used for oil in and on water detection, including interfaces.

Detection of oil in or on water Bela LiptakMN

The properties of oil and water are sufficiently different to make distinguishing them relatively easy. This article describes some of the state-of-the-art sensors used for oil in and on water detection, including interfaces. Oil on water Outfalls from ships and municipal or industrial waste treatment plants must be monitored because if the emissions contain hydrocarbons they’ll float on the water’s surface and form a barrier, which will prevent the oxygenation of the water and cause fish to suffocate. On-off, oil-on-water detectors are capable of measuring even a few drops of petroleum floating on the surface, so these alarm devices are used downstream of plant…

    Simple in concept, measuring the height or quantity of solids and liquids in tanks and vessels is amazingly complex in practice because there is a virtually infinite number of combinations of materials and operating conditions under which they must be measured. Solving the resulting problems with…
