Using the same diameter measurement techniques also allows ovality measurements.
The combination of multiple diameter measuring instruments, in biaxial, triaxial or quadriaxial configuration, allows you to obtain the ovality measurement. Systems with dynamic laser scanning are also available for determining the multi-section ovality profile.
Ovality measurement is one of the key metrological tasks in industry. Ovality refers to the deviation from an object's ideal circular shape and can significantly impact the functionality and quality of products. Ovality measurement is performed using precision instruments such as laser calipers, comparators, and laser distance meters.
Laser calipers are a highly precise and reliable tool used to measure the ovality of pipes, shafts, round objects, and other mechanical components. The precision of laser calipers allows them to detect even small deviations in the object's shape, enabling them to identify any manufacturing defects . Furthermore, laser calipers allow for quick and accurate measurements, reducing production time and costs.

Some applications of ovality measurement products
Technical insight
Ovality measurements are very important measurements in various industrial sectors, such as aeronautics, automotive and precision mechanics. To measure ovality, there are different technologies available, each with its own characteristics and advantages. In this article, we will explore six of these technologies: ovality measurements with vernier calipers, ovality measurements with industrial LASER distance meters, ovality measurements with contact micrometers, ovality measurements with digital comparators, ovality measurements with laser micrometers, and ovality measurements with ovality with bore gauges.
Ovality measurements with vernier calipers
Vernier calipers are very common measuring tools and offer a quick and precise measurement of ovality. It is possible to measure the ovality of external and internal surfaces with this instrument, thanks to their circular shape. The vernier caliper consists of a fixed part and a mobile part equipped with measuring tips, which can be replaced according to measurement needs. With vernier calipers, an accuracy of ±0,01 mm can be achieved.
Ovality measurements with industrial LASER distance meters
Industrial LASER distance meters are measurement technologies that use a LASER light beam to measure the distance between two points. These instruments can be used to measure ovality using an optical technique. The laser distance meter projects a laser spot onto a surface and measures the distance. By repeating this operation in multiple points of the surface, it is possible to obtain a three-dimensional map of the oval, allowing the most critical points to be identified. The accuracy of an industrial LASER distance meter can reach ± 0,1 mm.
Ovality measurements with contact micrometers
The contact micrometer is a mechanical measuring instrument that allows you to measure the dimensions of metal surfaces with great precision. It can be used to measure the ovality of an object, with an accuracy of ±0,001mm. The contact micrometer works by placing the contact surface between the object and the micrometer probe, which is then locked and the measurement is read on the built-in display.
Ovality measurements with digital comparators
The digital comparator is an electronic measuring instrument that allows you to compare the variations in size of an object compared to a reference value. It can be used to measure the ovality of an object by placing the comparator on the internal or external surface of the object. The digital comparator is a very precise instrument, with an accuracy that can reach ± 0,001 mm.
Ovality measurements with laser micrometers
The laser micrometer is a measuring instrument that uses a laser beam to measure the distance between two points. The laser emits a beam of light which is made to interfere with the object, causing a shadow to be cast. This measurement system allows to obtain a very high precision, which can reach ± 0,001 mm. The laser micrometer can be used to measure the ovality of an object by taking several scans of the surface.
