With focus on consistent performance and product longevity, the engineers at Bergan Marine Systems have developed a line of float level alarm sensors that provide industry-leading reliability. From the hot asphalt to cryogenic temperature of LNG tanks, we have a device that will deliver for you. Many of our sensors may be customized with optional secondary functions, such as UTI sampling ports, rising gauge stick, tank pressures or even temperature to minimize tank penetrations.

Bergan Marine Systems has a gauge to meet every demand, from our tried-and-true digital float gauge to our innovative digital level indicator. These gauges lay the foundation for precise inventory control and fuel management systems — with power consumption so low they can be powered completely with solar energy. The GUARD LEVEL digital float gauge (DFG) delivers a practical solution for simple and clean installation, precise inventory control and fuel management for tanks up to 64 feet (20 meters). Add optional integral tank temperatures and tank pressure sensors to provide the perfect setup for performance. For more than 40 years the professional team at Bergan Marine Systems has been designing and manufacturing unsurpassed quality marine instrumentation and equipment built to the highest standards – to provide that security and peace of mind: safe-guarding lives, property and the environment.  Whether you’re gauging in the heat of Texas or the arctic temperatures of Alaska, our Guard Level DFG is the proven and safe choice.

For more than 45 years, the professional team a Bergan Marine Systems has been designing and manufacturing high-quality marine instrumentation and equipment built to the highest standards required to guard life, property, and the environment, and consistently exceeding both regulations and expectations.

Now more than ever you need to safely and accurately measure cargo temperature in tanks and pipelines. Environmental concerns make manual gauging a
challenging task, and, until recently, a sometimes impossible feat. Bergan Marine Systems’s temperature sensors give you the ability to easily monitor tank temperature up to three points at a time, safely and efficiently.

Our Portable Barge Temperature Sensors are reliable, cutting edge solutions that requires absolutely no cabling or wiring to precisely measure in-tank cargo temperature. Fixed Temperature Sensors can be incorporated in our SMARTBARGE™ System to allow wireless data feeds to your management system software or our cloud servers.

Bergan Marine Systems designs custom electronic cabinets made to order in virtually any size for vessel tank monitoring and automation systems. We can also retrofit a system into your existing console – even if it was built by another manufacturer. With over 47 years of experience, we strive to set the industry standard and outdo the competition – making the best products available on the market.

Bergan's software solutions collect data from our various sensors for display to vessel operators as well as your shore staff in the office.

Our GUARD LEVEL® CMS+ (Cargo Monitoring Software+) is an embedded alarm and monitoring software providing a highly functional and user-friendly graphical software experience. CMS+ guarantees safe loading, monitoring and control of cargo, ballast and fuel tanks. The software comes preloaded onto a Bergan Master Control Unit (MCU) and Work Station Units (WSU) or can run separately on an onboard PC. This versatile Windows tile-based system makes it easy to configure and set up custom screens to manage your cargo.

While basic overview screens are fabricated with tiles representing cargo (HL and HHL (Overfill)), ballast, and service tanks – mix and match and designate tiles for specific loading needs. Cargo can also be color-coded according to customer preference. All monitored parameters are data logged. Choose what element to log and at what frequency.  Typical monitored sensors are level (with volume), tank temperatures (up to three points per tank), tank pressure sensor, manifold sensor, pump pressure, ballast, and bunker tank levels (volume) as well as vessel trim/ list and draft.

With our MODBUS interface, computer software such as CargoMax® can be loaded allowing for bi-directional online interface. Additional interfaces to vessel management systems are also included. The CMS+ can be run in master or slave mode accommodating one to multiple secondary displays.

Bergan's GUARD LEVEL® FMS (Fuel Management System) is an inventory management system for vessels that produces an audit trail to easily optimize fuel usage and reduce fuel pilferage. This intuitive tank gauging system has extended hardware and software capabilities.

The FMS main cabinet and associated CARGORADAR® or GUARD LEVEL® DFG (Digital Float Gauge) combined GPS interface provides for highly accurate daily fuel usage reports. By modelling the bunker tanks and having these strapped to +/- 0.15% accuracies, highly accurate tank volumes are calculated. The FMS software generates detailed daily reports and trip data information. With our optional data communication, data and reports can be accessed directly from our cloud servers.

The simplicity, reliability and low cost of manual valve control products makes them the best method of valve control on tank barges and larger ocean-going type ATB tank barges. At Bergan Marine Systems we know the importance of reliability and safety when it comes to valve actuation and have developed the leading valve product line in the industry – GUARD VALVE®. From its sturdy stainless steel handwheels with optional speed handle to the high visibility valve position indicator that allows a clear and unambiguous true valve position indication, explore what makes the GUARD VALVE® the preferred choice for shipyards and owners.

The GUARD VALVE® series of products are designed for manual control of non-rising submerged cargo and ballast valves and give a clear indication of the valve position even from across the deck. The main components are a stainless steel handwheel, a deck stand with attached valve position indication and stuffing box, a reach rod and a stainless-steel yoke with appropriate sizes for direct fitting to the valve stem. All parts can be customized to meet any requirements. The deck stand and associated valve position indication can be welded directly to the deck plate or, if required, be fitted for a flanged connection (three or four inches). Unique features include a DELRIN® thrust bearing which eliminates weight and associated wear on the valve. And, with the sliding yoke assembly design, the valve can be replaced without lifting the reach rod assembly.

Tank high-velocity pressure vacuum valves are critical safety devices. For over 25 years, our simple but technologically innovative deadweight principle PV valves have ensured safe operation on tank vessels worldwide. Through our long-term partnership with a world class manufacturer TankTech, each of our high quality valves can be supplied in a variety of sizes and materials, all quality-built to the latest IMO and Class requirements.

We also offer complete vent stack as well as flame screens for gas freeing operations.
