Automatically test and calibrate wind vanes Automatically test and calibrate wind vanes


The Symmetron VeriVane system is designed for quick and easy testing and calibration of Wind Vanes.

VeriVane automatically rotates the wind vane in precise steps, measures vane output and records detailed results in an Excel workbook.
The user has only to mount the vane and start the test.

VeriVane includes all hardware, fixtures and software required to produce test reports.
For additional VeriVane information click here.


Monitor the inclination of your met masts Record Elevation and Azimuth for any angle


The Symmetron Tiltometer is a tilt sensor with polar coordinates outputs.

- Operates in any position (3D).
- Elevation and Azimuth voltage output.
- RS232 port.
- SMS message when angle is found off limit (optional).

- Monitor a met mast's inclination at one or more heights.
- Optionally, receive an SMS when the inclination becomes lower than a limit (eg 89 degrees).
- Compatible with most dataloggers, including Stylitis models.

20 years of wind energy evaluation 20 years of wind energy evaluation

After 20 years and over 3000 Stylitis dataloggers for wind energy measurements Symmetron, a leader in the field, offers the expertise and technologies for successful exploitation of renewable energy resources in the 21st century.
Approved by international consultants and organizations, thousands of Stylitis-based campaigns have been successfully completed and applied.

The result is that members of the demanding MEASNET network depend on Symmetron dataloggers for their campaigns.


Wind Energy assessment: the basics Wind Energy assessment: the basics

Wind energy assessment may look simple in concept but requires a careful balance between required results and system complexity and cost.

This presentation may help you to decide.


Communication methods with measuring stations Telemetry with remote stations

Installation monitoring is key to successful measurement station operation and maintenance. To cover all needs, a variety of communication methods between a user and the measurement station are available:

- Broadband ADSL connections.
- Traditional GSM phone calls (modem to modem).
- Online GPRS connections.
- Data emailing.
- SMS data messaging.
- SMS alarms.
- Radio modem connections.
