Ultraflex Fuel and Water Level Sensor US5-E350 350 mm

Product description:

Ultraflex 20613Z US5-E350 is a specialized fuel and water level sensor with a length of 350 mm (13.8 inches), designed for use in boats, yachts, and other water and land vehicles equipped with fuel or water tanks. The device enables precise measurement of the liquid level in the tank, allowing real-time monitoring of fuel or water status and preventing unexpected engine or onboard system interruptions. The sensor is mounted vertically in the tank, usually in a dedicated mounting hole, and its installation is quick thanks to standard dimensions and compatibility with many level indicators. The float-based technology construction ensures reliable operation even under harsh conditions such as vibrations, temperature changes, or the presence of contaminants in the liquid. The housing made of corrosion-resistant materials guarantees long service life and safe use in marine environments. The sensor is compatible with most standard level indicators (e.g., 240–33 Ohm), making it a universal solution for a wide range of applications. The product is intended both for new installations and for upgrading existing measurement systems.
