Metrology, in its simplest form, is the science of measurement and plays a crucial part in the manufacturing and inspection process. This is how the manufacturer ensures that there are no dimension errors and that all parts are fitted to their proper measurements.

Manufacturing processes are costly, and manufacturers can’t risk even minor errors in the final products, which they might have to recall afterwards. Manufacturers evaluate the cost of a project and its reliability and accuracy to ensure no waste. The place of measurement in the process is determined by the type of industry that uses it. The science behind manufacturing quality assurance methods is used in our everyday lives. For example, Metrology keeps cars running well and computer processors running properly. A kilogram of rice you bought has to be a kilogram; speed measurements need to be accurate, GPS needs to tell you the right distance and more. Simply put, the modern industrialized world can’t exist without Metrology.

The Significance Of Metrology

As expectations for quality have increased, one of the problems has been that the human eye can’t measure with the precision necessary to make the best parts. There are several industries where accuracy is extremely important, which include the automotive, aerospace, and technology industries. Such industries rely heavily on metrology techniques such as coordinate measuring machines to ensure that the accuracy of components is as precise as 0.001 mm.

Let’s talk about the significance of metrology in the following 4 industries.

Aerospace and Automotive

The aerospace and automotive industries are based on the 3 main aspects that include-

  • Constant developments in design and innovation
  • Better products than their rivals to ensure competitiveness
  • Safety of their products since these companies move cargo and people. 

Both airplanes and automobiles rely on instrumentation to keep their systems within specific quality standards. Companies ensure the reliability of their products to the customers and ensure that the final product is safe for public use.

Metrology equipment facilitates the continuous evolution of efficient new systems and processes, from analyzing mass parts to calibrating the machinery and inspecting turbine blades, correcting inaccuracies in shape and ensuring proper vehicle assembly.


The world’s economy relies heavily on petrochemicals. The global oil and gas market size is increasing rapidly every year, and so is the importance of measurement technology in the petrochemical field. Many materials are derived from petrochemicals such as tires, fertilizers, plastics, industrial oils, etc. Metrology is used in the petrochemical industries to keep machines running. Power plants use the laser alignment technique as preventive maintenance routines. The stack flow and airflow monitoring strategy can be used for peak load management and energy saving. Data on dimensional changes, concentricity, equipment, and other critical areas that need to be investigated on turbines or rotating equipment can be obtained using 3D metrology techniques. 

Manufacturing And Automation

Most processes in today’s production plants are automated and need minimal human oversight. Many manufacturing processes rely on tools that can wear over time, leading to problematic dimensional errors. These devices are calibrated to specifications. Accuracy and precision of measurement are very important to meet safety and quality standards for public use or consumption of the products. For example, drug administration in pharmaceutical facilities, food safety in processing facilities, parts in aerospace and more.

Marine Environment

Measurement technology can obtain measurements of ships, tankers, and maritime domain vessels. The latest laser technology can replace or refurbish boat parts with precise measurements. Another recent metrology development in the shipping sector has been the ballast water treatment (BWT) transformation. BWT plans to improve the ship’s residual water process by installing a complete system to purify this water before it is discharged into the ocean and reduce the impact on the ecosystem.

In a nutshell, metrology is a key requirement in industrial environments. It creates accuracy in processes, fosters innovation and regulates safety standards.
