About Us

Over 30 Years of Engineering and Manufacturing Success!


KUS’ story begins with a fuel level sender. In 1984, our company’s founder had become unsatisfied after encountering a series of unreliable fuel level senders in the market. He then developed the world’s first reed switch liquid level sender for marine applications. The product took off and quickly became a top seller due to its reliability, accuracy, and durability. After the global success of KUS’ initial reed switch level sender, a series of product innovations followed.

KUS began developing more complex, integrated liquid level senders for the medium and heavy-duty commercial vehicle industry. Its core product offerings included engine monitoring instrumentation and Diesel Exhaust Fluid (DEF)/AdBlue level senders and tank assemblies.

Now KUS develops and manufactures a range of application solutions for the Marine, Vehicle, and Industrial industries. Fuel level senders still remain an important part of our business.
