Delivering Safeship®

Fire is the second greatest cause of loss of life and property at sea, after sinking. Because of this, we have developed our mission of Safeship® to minimise maritime loss by applying innovative solutions to the industry. As part of this mission, Portalevel® MAX MARINE PLUS is one of our flagship products, which aims to improve the safety and efficacy of marine fire suppression systems and in turn minimise losses due to fire. The combined accuracy, versatility and operational simplicity of Portalevel® MAX MARINE PLUS make it a solution which can be easily applied with minimal impact on the operation of a marine structure to facilitate a higher level of operational safety.

Frequently asked questions

The Portalevel® MAX MARINE PLUS can measure the level of a wide variety of liquids. The primary application is for checking the liquid level in fire suppression cylinders. These agents commonly include: CO2, FM200™, NOVEC™ 1230, Halon agents, FE-13™, FE-25™, NAF S III™ and, all core Clean Agent systems. However, the Portalevel® MAX MARINE PLUS has been shown to work on other liquids such as water, fuel, LPG and even mayonnaise in the processed food industry.
The Portalevel® MAX MARINE PLUS can identify the liquid level to ±1.5 mm of the actual liquid level. When using the Portasteele® CALCULATOR to convert the liquid level to agent weight, the results are accurate to within 1%.
With the Portalevel® Max Marine Plus, you also get an extension rod that allows you to measure the liquid level in banked cylinders up to four deep.
The Portalevel® MAX MARINE PLUS is one of the most powerful we have developed and works on a large range of cylinder sizes. We have an extensive range of products that can measure anything from 10 cm to over 15 m diameter, so get in touch to find out which unit is suitable for your application.
No, you can use any ultrasonic gel, available in most pharmacies, as well as petroleum jelly. Water will also work, but in hot environment needs very regular application.
No, unfortunately above this temperature CO2 converts into a supercritical fluid state and your cylinder will no longer have a liquid level to measure. We recommend testing CO2 in lower temperatures. Please, get in touch if you need recommendations for hot climate CO2 monitoring.
Yes, however, these agents are far more stable at higher temperatures that CO2, and although the liquid level will naturally rise with increased temperature it is far less than with CO2 and, therefore, can still be tested.
Yes, this unit is specifically designed to work despite the presence of a siphon tube.
The three calibration modes are deigned to offer greater flexibility for the Portalevel® MAX MARINE PLUS to test a wider range of cylinders, despite challenging measuring conditions. CAL 1: This is the standard setting to be used in most cases. This will work when the trend in readings you observe goes from high to low with a large drop-off CAL 2: This mode is to be used when the difference between high and low readings is great, or if CAL 1 is insufficient. CAL 3: This mode is to be used when the difference between high and low readings is small, and/or CAL 1 or 2 is insufficient.

Why Monitoring CO2 Fire Systems at Sea is Crucial: Introducing Portamarine®

In the maritime industry, ensuring safety isn’t just a best practice—it’s a necessity. According to Lloyd’s List, almost 10% of all total losses at sea in the last decade were caused by fires onboard. As NTSB Chairman Robert Sumwalt rightly said, “Safety isn’t something you have, it’s something you do.” When lives are at stake, neglecting fire systems and their maintenance is simply unacceptable.
