INOX Fluid Level Indicator: Precision Monitoring for Industrial Liquid Levels

In various industrial settings, the precise monitoring of liquid levels is crucial for maintaining operational efficiency and safety standards. One of the revolutionary tools contributing to this aspect is the INOX Fluid Level Indicator. Liquid level gauges facilitate quick and easily readable visual inspections. These gauges offer convenient viewing across various industrial settings, proving particularly suitable for bearings, transformers, and numerous other non-pressure applications. Constructed with Stainless Steel and glass tubes, they ensure prolonged durability and service life.

Understanding the INOX Fluid Level Indicator

The INOX Level Indicator is a precision technology crafted to accurately measure liquid levels in tanks or vessels. Constructed using top-tier stainless steel and durable materials, it is specifically engineered to endure severe environmental conditions and a wide range of chemical compositions. Its versatility extends its applicability to a broad spectrum of industries, encompassing the medical and food sectors, chemical and petrochemical industries (both onshore and offshore), mining, water treatment (including desalination), and numerous other fields.

INOX - Where Accuracy Meets Reliability.

The Modular System: A Fusion of Versatility and Cost Efficiency

Liquid level gauges are constructed based on a modular system, combining a diverse array of options and cost-efficiency. These gauges excel in meeting the most stringent demands for corrosion resistance and stability due to the use of stainless steel (316L) as the base material.

INOX equipment boasts remarkable resistance to acids and caustics, proving itself seawater-resistant and widely embraced across a vast spectrum of industrial applications. 

In contrast, non-ferrous metals such as Al, Zn, Sn, Cu, and their alloys lack these exceptional characteristics.

INOX devices are engineered to meet the highest standards in functionality and safety. They can be safeguarded in accordance with ATEX directives. Additionally, special sealings made of Kalrez®, capable of enduring temperatures up to +360°C, are available upon request.

Banjo bolt for liquid level gauges

The INOX liquid level gauges are affixed to your equipment using a banjo bolt, offered in two distinct versions. One variant features a banjo bolt with a straightforward hole, facilitating the connection of the indicator to the fluid system, allowing observation of the liquid level.

The device does not need to be rotated for assembly. It is simply placed onto the pre-mounted adaptor and secured with the hollow screw. 

Conversely, the opposite side remains closed. An alternative banjo bolt boasts a through bore, strategically designed to grant convenient access to your system, facilitating the installation of sensor technology, such as our optical sensor for low-level detection.

This additional port not only allows for easy installation of a sampling port to assess oil cleanliness but also offers the option to install a thermometer for added functionality.
