Level Transmitters (296 suppliers)

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level.

Liquid Level Floats (46 suppliers)

Liquid level floats, sometimes known as float balls, are spherical, cylindrical and similarly-shaped objects - made from either rigid or non-rigid material - that are engineered for buoyancy in water and other liquids. They are used for surface demarcation, level measurement, flow control, cable support, and to block UV light. They may also be designed for integration with valve, switch or fluid-instrument mechanical assemblies, to control or monitor liquid levels and tank volumes.
