Our robust Marine Fuel & Water Tank Level Sensor ensures precise liquid level monitoring for gasoline, diesel, fresh water, and even sewage. Constructed from superior 316L stainless steel for exceptional corrosion resistance, it features an ultra-reliable reed switch sensor and is IP67 waterproof rated for harsh marine environments. Designed for universal compatibility with tanks ranging from 250mm to 1000mm, it supports multiple installation types (BSP, NPT, 5-hole flange) and various output signals (resistance, current, voltage) for seamless integration with existing marine gauges. Easy top-mount installation makes it an ideal upgrade or replacement for yachts, bass boats, pontoons, and commercial vessels. 
Frequently Asked Questions
- Will this level sensor accurately read different types of liquids like fuel, fresh water, or even sewage?
- Yes, this sensor is engineered for broad compatibility. Its internal float system uses materials specifically chosen for the medium: plastic for oil, 304 stainless steel for drinking water and chemicals, and 316 stainless steel for sewage, ensuring reliable and accurate readings across various liquids.
- Is the installation process complex, especially with different tank types or existing gauge systems?
- Installation is designed to be highly versatile and straightforward. It supports common marine standards including BSP1-1/2", BSP1-1/4", and NPT threaded connections, as well as a standard 5-hole flange mount. Furthermore, its multiple output options (resistance, current, voltage) ensure universal compatibility with most existing marine gauges.
- How durable is this sensor in harsh marine environments, particularly against corrosion and water ingress?
- Constructed from marine-grade 316L stainless steel for maximum corrosion resistance, this sensor is built to withstand extreme marine conditions. It boasts an IP67 waterproof rating, protecting against dust and temporary immersion in water, and operates reliably in temperatures from -40℃ to +85℃.
