Our marine approved liquid level sensor is a magnetic float on a reed switch for control and indication in an marine environment.

Marine Level Switch Overview

These marine level switches are engineered to provide precise liquid level control and indication in the most demanding maritime environments. Holding Bureau Veritas Marine Type Approval, these sensors are purpose-built to withstand relentless exposure to seawater, salt spray, and extreme mechanical stress found in ballast tanks and on open decks.

Constructed from high-grade 316L stainless steel, our marine level switches offer the robust corrosion resistance and mechanical integrity required for safety-critical applications on oil and chemical tankers. With customisable options including stem lengths up to 6 meters, multiple switch points, and IP68 ingress protection, they deliver reliable performance for monitoring hazardous, flammable, or high-temperature cargo while ensuring compliance with stringent industry safety standards.

Frequently Asked Questions

Which Marine Type Approval does the Deeter float switch hold?
The Deeter Marine Type Approved F/S-FP Series Float Switch holds Bureau Veritas Marine Type Approval under certificate 53346/A0 BV. The certificate, product specification and vessel requirements should be checked when selecting and installing the switch.
Where are marine level switches used on a vessel?
Marine level switches can be used for point-level monitoring and control in tanks and other liquid systems, including applications involving ballast, bilge, fuel, oil or process liquids. The exact product must be selected around the liquid, tank, environmental conditions and any hazardous-area requirements.
How does the Deeter marine float switch resist harsh conditions?
The F/S-FP marine float switch uses 316L stainless steel for its housing and wetted components and is available with IP66 and IP68 protection when fitted with a suitable cable gland. Its construction is intended for demanding environments where corrosion resistance and mechanical strength are important.
Can the Marine Type Approved F/S-FP be customised?
Yes. Published options include sensor stems up to 6 metres, as many as seven switch points, mixed normally open and normally closed switching, alternative mounting arrangements and cable-entry choices. Temperature, pressure, float, stem and certification requirements should be confirmed for the individual application.
