What are the two basic types of oil quantity tank units?

• A. Capacitive and Inductive
• B. Float Type and Solid State
• C. Optical and Magnetic
• D. Mechanical Float and Digital Readout

Answer: (B)

Measurement method is the core idea here. Oil quantity tank units fall into two main families: a float-type, which is a mechanical device where a buoyant float rides on the oil surface and drives a linkage or magnet to indicate level on a gauge; and solid-state, which uses electronic sensors with no moving parts to detect level and output a signal to the display. The float type is simple and rugged but can be affected by sticking or fouling, while solid-state sensors offer more reliability and consistent readings across temperature and vibration. Other options describe specific sensor technologies or outputs, but they aren’t the two broad categories used to classify oil quantity tank units.
