About Us

Over 30 Years of Engineering and Manufacturing Success!


KUS was founded in 1984, when the founder had become disenchanted with the unreliable fuel level senders available in the market. He then developed the world’s first reed switch level sender for marine applications, which quickly became a global success story.

A succession of product innovations rapidly followed: more complex integrated liquid level senders for the medium-and-heavy duty commercial vehicle industry, engine monitoring instrumentation, Diesel Exhaust Fluid (DEF)/AdBlue level senders and tank assemblies, and more.

KUS. Committed to Excellence.


As one of the world’s leading manufacturers of liquid level senders, Diesel Exhaust Fuel (DEF) level senders, and gauge instrumentation, KUS manufactures components for the on-road and off-road automotive, marine, and industrial sectors.
