Outstanding Performance & Precision Products for Marine Applications


Whether installed in a small pleasure craft or an ocean-going vessel, KUS products offer outstanding performance and precision – while providing exceptional value. All products go through environmental chambers that simulate the hottest and coldest climates and shock benches that simulate the roughest of terrain conditions.

A Solution For Every Challenge

With its longstanding familiarity with the stringent requirements of the marine industry, KUS has developed a comprehensive suite of products to address the needs of boaters, designers and engineers.

Manufactured To The Highest Standards

Out on the open water, there is no room for error. That’s why boat designers and engineers look to KUS when performance is critical. We use the highest caliber materials and manufacture our products to the most rigorous standards. Because the reputations of our customers are at stake every time they go into production, we understand that quality is of the utmost importance.

Continuous Innovation Moving Forward

KUS’ marine product line includes digital liquid level sending units, digital engine monitoring instrumentation, and analog-to-digital converter boxes.

Meanwhile, our digital product line is NMEA 2000 certified, which means it allows for an easy, plug-and-play installation.

Level Senders

KUS liquid level senders are commonly used to detect fuel levels, water levels, or holding tank levels. Our electronic level senders use reed switch and magnetic field technology. The float is the only moving part of the sender, thereby minimizing the chances of mechanical failure. KUS liquid level senders are preferred by OEMs over thick-film, swing-arm-type level senders for their reliability and durability.

We work with tank manufacturers to supply standard off-the-shelf senders, as well as calibrated units designed for the special tank geometries.

We also work with boat and yacht manufacturers directly to provide custom senders for the on-board system with switch or alarm requirements.

Gauge Instrumentation

KUS has over 20 years of experience supplying gauge and instrumentation for the marine industry; we know the importance of quality performance in the harshest environment.

Our gauge instrumentation bodies are IP67 rated with anti-fogging and scratch resistant lens cover; this means KUS gauges are waterproof and built to withstand open water conditions. Our analog gauges are also equipped with back-lit by long-lasting LED lights that provide backlighting. This ensures that installed marine gauges are easy to read at night or under the sun’s glare.

KUS offers complete sets of gauges for the inboard and outboard engines, as well as other gauges to help you have a safer experience out on the water.

NMEA Certified Products

NMEA 2000 network is a Controller Area Network (CAN) bus technology that is becoming more widely adapted by the marine industry for boats and yachts of all sizes. It is a plug-and-play network with no master nodes to configure, and can support hot swappable devices.

The NMEA 2000 network consists of a backbone with terminal plugs at both ends, a network of certified devices, drop tees, and drop lines branching from the backbone to each of the network devices.
