Which instrument is described as the Digital Free Water Detector?

• A. DFWD
• B. BS&W meter
• C. FSII analyzer
• D. Visual test gauge

Answer: (A)

The main idea here is recognizing the instrument that provides a digital readout specifically for detecting free water in fuel. The Digital Free Water Detector is designed to sense free water contamination and present a clear digital readout (often with alarms), making it quick and unambiguous to determine whether water is present and in what amount. This focused capability is what sets it apart from other tools. A BS&W meter measures water and sediment content in fuel but isn’t a digital free-water detector by design. An FSII analyzer checks for fuel system icing inhibitor levels, which is a different parameter entirely. A visual test gauge relies on visual judgment and lacks a digital readout. So, for detecting free water in fuel with a digital indication, the Digital Free Water Detector is the right instrument.
