Easy-Laser E910

Easy-Laser® E910 Flange is a system used to measure flange flatness of windmill towers, wings and hubs, tower bases, etc. It can also be used for parallelism measurement.


Measure windmill tower flanges of any size

See the result as a true 3D image in the display unit directly after measuring. Then evaluate the result easily with different calculation settings, for example, three-point reference, best fit, or all positive. This can also be done directly on-site without having to stop to go to a PC with separate analysis programs, which was the case previously. This makes production much more efficient.

The system includes laser transmitter D22 with manual rotatable head, and with the option of deflecting the laser beam 90°. With a few more accessories, the system can also be used to check the parallelism of the two tower flanges. In the measurement system’s display unit it is possible to generate a PDF report containing graphs and measurement data. All information about the measurement object is documented.

For all types of flanges

Easy-Laser® Flange systems can be used on all sizes of flanges, regardless of diameter. You can measure 1 to 5 circles of measurement points, for example inner, middle, and outer circles, in order to see the taper of the flange. Each circle can have 6–180 measurement points. The program guides you graphically step-by-step through the entire measurement, which quickens the measurement process. Three methods are available: Full circle measurement, Sectional measurement, and Partial measurement.

Parallelism of tower flanges

Easy-Laser® enables you to measure and check the parallelism of the flanges. This can be done in several ways, as shown to the right with system E910 for example. In addition to the standard equipment, two tripods and an angular prism are required.

Measurement of flange with Easy-Laser® E910 system

Evaluate directly on site

When the measurement of the flange is complete, the digits must then be interpreted. Easy-Laser® Flange systems make this extremely easy to do. And you can even do it on-site, without having to go to a PC with separate analysis programs. You can evaluate the result with different calculation settings, for example, “three-point reference”, “best fit” or “all positive”. The result is shown via graphics in true 3D.
