The Contaminated Condensate Return Alarm is an oil-water interface detector system for inspection and other types of tanks. The flange-mounted probe is installed in the first compartment (contaminated return) of the inspection tank. There, the interface probe continuously monitors a predetermined oil/water interface level in the inspection tank or in a tank of any shape or size.

Visual and audible alarm signals are provided for local and/or remote response modes. Control box relay pick-offs are available to automatically actuate pumps, valves and other control instrumentation.

The solid-state system is IMO-approved and rated intrinsically safe for use in hazardous areas.
