CASE STUDY
Case study: How to measure liquid levels in tanks on ships? Level sensors for the marine industry
Reliable liquid level monitoring plays a key role in ensuring the safety of marine vessels and their compliance with regulations. Many vessels continue to struggle with problems of inaccurate level measurements, particularly in deep tanks where traditional measurement methods prove inadequate. Our company partnered with a leading marine operator to install a tank level monitoring solution across their fleet. From this case study, you will learn how our measurement system solved the customer's measurement problems while meeting DNV and ATEX standards. We'll show you how the right sensors for tank level monitoring can make a difference to marine vessels and improve safety at sea. Read on!

Why is accurate tank level monitoring crucial in the marine industry?

Our experience in the marine industry shows that accurate tank level monitoring is one of the cornerstones of effective ship management. The tank level sensor systems we install play a significant role in the shipbuilding industry.

Accurate level monitoring is essential for several reasons:

  • Ensuring safety: Our systems prevent liquid overflow and enable the correct weight distribution to be maintained.
  • Increasing operational efficiency: Real-time data optimises fuel consumption and cargo management.
  • Environmental protection: Precise measurements from wastewater level sensors prevent accidental spills.
  • Cost control: Accurate readings from fuel level sensors optimise inventory management.
  • Regulatory compliance: Tank level sensors comply with international maritime regulations.

Vessels operating without precise level monitoring face a higher risk of environmental violations, operational inefficiencies and safety incidents. With our experience in marine applications, operators can trust our systems to provide continuous, reliable data for key decisions.

How to accurately measure liquid levels in deep tanks on ships? The client's challenge

Our collaboration with this marine client began when they approached us with a challenging problem of measuring liquid levels in tanks. After more than two decades of experience in level measurement on ships, they needed a solution that would revolutionise their level and draft measurement system.

The main objectives were to find a level sensor that could reliably operate in harsh marine environments. Key requirements included:

  • Ability to measure depths from 0 to 25m.
  • Compatibility with existing air purification techniques.
  • Resistance to harsh marine conditions.
  • Meeting stringent marine certification standards.
  • Integration with shipboard automation systems.

The project proved particularly challenging as it required specialist approvals and certification for marine applications. Initially, we did not have the product or certification to meet these requirements. Working with ship owners and shipyards, we developed a measurement system that integrates seamlessly with shipboard automation, withstands the corrosive marine environment and provides accurate measurements continuously. As a result, we developed a specialised sea level sensor to meet these requirements.

How does precise hydrostatic level measurement improve tank management on ships? Our solution

We have developed a specialised titanium tank level sensor that meets the stringent requirements of this and our other industry customers. Our solution combines proven piezoresistive sensor technology with marine grade materials to ensure reliability in demanding shipboard conditions.

The JUMO MAERA S29 SW hydrostatic level sensor is a key component of our solution that offers:

  • Advanced protection: Removable protective cover for the sensor diaphragm.
  • Wide measuring range
  • Unparalleled durability: Titanium or stainless steel versions for maximum durability.
  • Certification and approval: Full ATEX explosion protection and DNV approval.
  • Complete integration: Wide range of installation accessories.

Our solution provides accurate, continuous measurements in harsh marine environments, while enhancing traditional air purification technology to reduce air consumption. Thanks to 20 years of working with marine customers, our systems integrate seamlessly with existing onboard automation, providing real-time data for better tank management.
