What is the difference between a float switch and a capacitive liquid level sensor?

A float switch uses a buoyant float that moves with the liquid to open or close a mechanical/reed contact, making it simple and reliable for point-level detection. A capacitive sensor detects level changes electronically without moving parts and can support non-contact or continuous sensing; choose based on whether you need a single trigger point or continuous level reading and whether contact with the liquid is acceptable.

Can these level sensors work with fuel or oil, not just water?

Many models are rated for water, fuel, oil, and other liquids, but suitability depends on the wetted-material specification and sensing technology listed for that product. Check the stated compatible media, body material, and temperature range on the specific listing to confirm it matches your fluid.
