With the rising demand for high-performance lubricants, manufacturers are under mounting pressure to enhance efficiency and lower costs. Technological and process innovations are crucial to address these challenges while ensuring product integrity and adherence to industry standards. The global lubricant sector is poised for significant growth. Equipped with cutting-edge technology, this comprehensive solution enables to capitalise on the increasing worldwide demand and establish a strong foothold in this lucrative market.
What is driving the increase in demand for Lubricant Oil Worldwide?
Lubricant oil is essential in the machinery industry as it significantly reduces friction between moving parts. Lubrication forms a thin layer between these components, effectively decreasing friction. Lubricating oil addresses problems such as overheating, scuffing, rubbing, and corrosion, aids in preventing wear and tear, thereby extending the equipment's lifespan, and provides protection against corrosion. This not only enhances the longevity of the equipment but also improves its performance.

The Need for Bulk Storage Tanks is crucial for businesses operating in sectors such as energy and oil manufacturing. Given the rising demand in the lubricant oil industry, companies need bulk storage tanks to successfully manage large volumes of diverse oils, which aids in price discounts, minimises waste, and provides better protection and operational productivity. The capability to hold multiple types of oils in bulk enables businesses to efficiently mix and manufacture various formulations, thereby fulfilling the diverse demands of their customers.
In today's rapidly evolving industrial landscape, where downtime can incur significant financial repercussions, having a reliable bulk oil storage system is imperative, not optional.
Safety Guidelines
The oil and gas field is required to comply with a range of regulations that call for redundant measurements in the processing operations. These strict regulations are designed to minimise the risk of tank leaks and the related environmental hazards, as well as to ensure the health and safety of workers and surrounding communities.
Why Measuring Sensors?
During the scorching summer heat, lubricants tend to release vapour. Lubricant oil is a low-reflective and fairly costly product: customers need a technology that can accurately and reliably monitor the exact content of each tank for optimised processes and inventory control. Furthermore, some tanks require contactless measurement due to the presence of agitators. Given the significant number of tanks, the need for automated data transmission to a control room is evident.

Types of Measuring Indicator Sensors:
The standard types of measuring indicator sensors for oil tanks include float level indicators, ultrasonic sensors, radar sensors, capacitance sensors, and hydrostatic (pressure) sensors. These sensors leverage various technologies to detect and convey liquid level information to a display or control system.
What Are Radar Sensors?
Radar Liquid Level Sensors provide a dependable approach for assessing material levels in tanks and vessels without requiring physical contact. These sophisticated devices send microwave pulses downward toward the liquid or solid surface, and the sensor determines the distance by timing how long it takes for the reflected signal to return, thus accurately indicating the level.
Their operational mechanism renders them resistant primarily to difficult process conditions such as high temperatures, pressure fluctuations, vacuum, or the presence of vapours and dust, ensuring reliable accuracy where other technologies might struggle. As a result, radar sensors are extensively used in various industrial sectors, including petrochemical and chemical processing, for essential level monitoring and control tasks. This robust, non-invasive technology delivers reliable and precise level data that is crucial for efficient operations and safety. Without a radar level meter in the plant, utilising manual measurement may result in increased labour costs and lead to safety-related incidents.
Radar level transmitters operate similarly to ultrasonic sensors, but they generate electromagnetic radio microwaves instead of sound waves.
Types Of Radar Level Sensors:
TDR Radar (Time Domain Reflectometry)
FMCW (Frequency Modulated Continuous Wave) Radar
The Frequency Modulated Continuous Wave (FMCW) Radar Sensor is more sophisticated than other sensors; it can continually and accurately detect the level in process tanks, even when the tanks are being filled. Its transmitters are unaffected by high temperatures, internal tank movement, and agitators.
Benefits Of Radar Level Sensors:
Continuous Remote Monitoring with SCADA or PLC systems: Radar sensors, contactless and remote monitoring, continue unaffected by pressure variations, foam, heat, vapour, dust, internal agitators, or during the tank filling process. Radar Sensors deliver constant level readings and are compatible with SCADA or PLC systems, enabling distant monitoring of lubricant oil levels in the tanks.
Enhanced Security Preventing Overfilling & Pipeline Leaks: Radar Sensor technology supports remote monitoring, enabling quick responses to changes in levels and helping to avert potential issues such as overfilling, pipeline leakage, and contamination. It also helps prevent pressure-related problems or accidents that could lead to environmental harm or personal injury.
Stock Inventory Management: Effective record-keeping using radar sensors helps reduce surplus stock. Radar sensors deliver precise information on lubricant oil levels in storage tanks, enabling continuous monitoring. Radar sensors ensure precise level information, which in turn prevents downtime and losses.
Protection from Theft: The company allocates a significant portion of its resources towards security measures. Lubricant oil is a valuable product that requires consistent and continuous monitoring of product levels to enable operators to detect discrepancies and potential theft.
Live Update to Stakeholders: Improving inventory management, safety, and operational efficiency. This technology facilitates remote monitoring. Stakeholders can access real-time information on lubricant levels, enabling them to make proactive decisions.
