Float Type Oil Quantity Tank Unit uses what to detect oil?

• A. A Float
• B. A Nickel Alloy Wire
• C. A Transducer Coil
• D. A Magnetic Reed

Answer: (A)

Floats ride on the oil surface and move up and down as the oil level changes. In a Float Type Oil Quantity Tank Unit, the vertical position of that buoyant float is what indicates how much oil is present—the float acts as the sensing element, translating level into a reading or signal. Other components like nickel alloy wires, transducer coils, or magnetic reed switches are different sensing technologies and aren’t the primary element that follows the liquid level in this type of unit. Some designs might use a magnet in the float to trigger a reed switch, but the fundamental detector is still the float itself tracking the oil surface.
