Oil Content Monitor Offered By Salwico

—Literature Available The Salwico Controil is an infrared type oil content monitor for oil in ballast water from tankers that is notable for its ease of use and simplicity of installation, yet with sophisticated functional ability. The portable hand-held control terminal can be deployed wherever convenient.

A product of Salen & Wincandler AB of Sweden, the Controil is fully approved under IMO Resolution A. 393 (X) and also satisfies the design criteria of IMO Resolution A.496 (XII). It is available for both retrofitting and newbuildings. Only three small penetrations are required between safe and hazardous areas—two for the 8-mm sampling pipes and one for the sample feed pump drive.

Water drawn by the sample feed pump from the overboard discharge line is screened for solids before a small portion of the flow is intermittently drawn off by a secondary sampling pump in the analyzing unit, situated on the gas-free side of the bulkhead. PPM signals are passed through a two-wire communication loop to the computing unit, which also comprises a display and an alphanumeric printer. The handheld control terminal, also used for operator input, can be plugged in virtually anywhere on the communication loop.

The flow meter (required only for "new ships" as defined by IMO) is an ultrasonic flow meter or a differential pressure-sensing flow meter.

The two models complement each other, and selection of the flow meter is dependent upon price, location of installation, type of cargo, system design, and accuracy required.
