Ultraflex Fuel and Water Level Sensor S3-A400

Product description:

The S3-A400 Ultraflex fuel and water level sensor is an advanced measuring device designed for precise monitoring of liquid levels in fuel and water tanks, mainly used in boats, yachts, specialized vehicles, and industrial machinery. The product is dedicated to cooperation with onboard monitoring systems, analog or digital indicators, enabling real-time control of the medium quantity in the tank. The sensor operates on the principle of liquid level measurement using a submerged probe that generates an electrical signal proportional to the height of the liquid column. Installation is done by mounting the sensor at the top of the tank using dedicated mounting holes, ensuring tightness and resistance to environmental conditions. The device is distinguished by high corrosion resistance, tightness, and compatibility with various types of tanks made of metal or plastics. The S3-A400 Ultraflex is especially valued in the marine and automotive industries for its reliability, ease of installation, and ability to operate in harsh conditions such as vibrations, variable temperatures, or contact with aggressive media.
