Brazilian Oil Tankers Install Radar Level Gauges
In Brazil, oil transportation is a vital lifeline for the national economy. Numerous oil tankers ply the oceans day and night, carrying the heavy responsibility of long-distance oil transportation. Accurately measuring the liquid level within tankers is crucial for ensuring safe transportation and efficient management of oil. In September 2025, Jujea successfully helped a Brazilian oil transportation company solve its level measurement challenges with its advanced radar level gauges and comprehensive solutions.
I. Level Measurement Challenges for Brazilian Oil Tankers
This Brazilian oil transportation company owns a large fleet of tankers that frequently travel between major oil production and consumption areas around the world. Previously, the traditional level measurement equipment they used had numerous issues and was unable to meet the measurement requirements of the complex operating conditions of oil tankers.
From a measurement perspective, cargo ships navigate the ocean, facing severe pitch and roll, placing extremely high demands on the stability of level measurement equipment. Furthermore, the humid, salty, and corrosive marine environment makes measurement equipment made of standard materials susceptible to corrosion, resulting in reduced measurement accuracy and equipment damage. Furthermore, the wide range of temperature and pressure fluctuations within oil tankers further complicates level measurement.
As for the measurement equipment itself, the company's previously used level gauges suffered from low accuracy and large errors, making them unable to provide accurate level data for oil loading, unloading, and transportation. This often led to under- or over-loading during loading and unloading, resulting in not only financial losses but also safety hazards. Furthermore, the traditional level gauges' single signal output made them difficult to effectively integrate with the vessel's automated management system, preventing real-time monitoring and remote management, significantly hindering the company's operations and management.
II. Jujea Radar Level Gauge Solution
After deeply understanding the needs and pain points of a Brazilian customer, Jujea, leveraging its R&D and production capabilities as a professional
manufacturer, tailored a radar level gauge solution based on advanced technology.
(I) Complex Operating Conditions of Radar Level Gauges
The Jujea radar level gauge offers a range of exceptional specifications, perfectly suited to the complex measurement environments of oil tankers. With a measurement range of 0 to 20 meters, it meets the level measurement requirements of oil tankers. With an accuracy of up to ±1mm, the radar level gauge provides extremely precise level data for oil loading, unloading, and transportation, effectively preventing under- or over-loading, saving costs and reducing safety risks for businesses.
The RS485 signal output interface facilitates connection to the vessel's automated management system, enabling real-time transmission and remote monitoring of level data, facilitating centralized management and dispatch of oil levels on board.
The housing and junction box are constructed of stainless steel, which offers excellent corrosion resistance and withstands the high salinity and humid air of the marine environment. The antenna lens, facing the cargo, is constructed of PTFE/PEEK. These high-quality materials ensure the radar level gauge's long-term stable operation in harsh environments.
The IP68 protection rating effectively prevents dust intrusion and, to a certain extent, water intrusion, ensuring proper operation even when the vessel is exposed to inclement weather or waves, and facilitating installation and maintenance.

(II) Installation and Commissioning Service
After deciding to use the Jujea radar level gauge, technicians developed a detailed installation plan based on the specific structure and layout of the cargo ship's oil tanks, ensuring the radar level gauge's installation location would achieve optimal measurement results.
During the installation process, technicians strictly outlined every installation standard required of the installer, inspecting key aspects such as cable connections and flange installation to ensure a secure installation and stable signal transmission. After installation, technicians remotely commissioned and calibrated the radar level gauge via video. By simulating different liquid levels and operating conditions, they tested and optimized the device's measurement accuracy, signal output, and other performance characteristics to ensure accurate and stable operation.
(III) Service & After-Sales Support
To ensure that the customer's operators are proficient in the use and maintenance of the Jujea radar level gauge, the Jujea technical team provided product training videos. The training covers the equipment's operating principles, operation methods, routine maintenance, and common troubleshooting, enabling operators to quickly master relevant knowledge and skills.
Jujea has also established a comprehensive after-sales support system, providing customers with 24-hour response service. Customers can contact Jujea's after-sales team at any time if they encounter any issues during use. The team will provide prompt remote technical support to resolve the issue and ensure the normal operation of the equipment.
III. The Value of Radar Level Gauges
Since the Jujea radar level gauges were officially put into use on Brazilian oil tankers at the end of October 2025, they have achieved remarkable results.
In terms of measurement accuracy, the radar level gauges maintain a high precision of ±1 mm, providing accurate data for oil loading and unloading, effectively avoiding under- or over-loading caused by inaccurate level measurement.
In terms of data transmission and management, via RS485 signal output, level data can be transmitted in real time to the vessel's automated management system and the company's monitoring center, enabling real-time monitoring and management of the vessel's oil tank levels. In terms of equipment stability and reliability, the Jujea radar level meter, thanks to its superior material quality, protection level, and anti-interference capabilities, has consistently maintained stable operation despite the severe weather and complex operating conditions experienced by the cargo ship, without any measurement errors or equipment failures caused by environmental factors. This has earned high recognition and praise from customers.
The head of a Brazilian oil transportation company stated, "Jujea's radar level meter has solved our long-standing level measurement challenges. Its precise measurement, stable performance, and comprehensive service have enabled us to manage oil transportation more efficiently and safely. We will continue to collaborate with Jujea and incorporate their
products and solutions on more cargo ships."
This successful collaboration with a Brazilian customer not only demonstrates the superior performance and advantages of Jujea's radar level meter in the oil transportation sector, but also further underscores
Jujea's ability as a professional manufacturer to provide high-quality flow measurement solutions to customers worldwide. Going forward, Jujea will continue to uphold the principles of innovation and service, continuously improving product quality and technical capabilities, solving measurement challenges for customers in more industries and promoting the development and application of flow measurement technology.
