Windmeter - Digital Anemometer

Last update 20 SEP 2021

WindMeter is a high performance digital anemometer (wind gauge), suitable for monitoring wind plants and wind speed in ski lifts, motorways, airports and ridge ways.

Easy mounting anemometer - measure windspeed

WindMeter has been designed to give reliable readings. The sensor has a mechanical plug-and-play. The use RS485 digital output simplifies the wiring especially in stations with multiple instruments and gauges, so that it’s possible to create a unique chain (bus) at the confluence of the different sensor data. WindMeter is available with a M8-4 pole connector that allows a faster and superior installation and maintenance, as well as the possibility of installing a multi-probe plug&play for easier maintenance controls. It is compatible with the Ammonit Meteo-40 data-logger (on bus RS485). Also available in the MEASNET centre’s calibrated version.

Key features

Standard Modbus RTU RS485 port to assure correct reading even at 500m distance.
Average and maximum wind speed measurement
Temperature measurement
Extreme weather resistance
Ease of installation to the structures
Calibrated one by one, for maximum accuracy
Anti-icing option

Accessories

Vanemeter
Support rod
USB/RS485 interface cable
USB/MICRO-USB smartphone adapter
Sm configuration for Android smartphone and tablet
SMCONFIG allows you to configure Windmeter in the field from your Android smartphone. It is no longer necessary to bring sensor back to the laboratory for configuration. The software allows you to:
- configure Windmeter.
- make a diagnosis of the basic functions.
- log irradiance, temperature and wind (Sunmeter Wind only) readings.
The software is available for free on this page in the downloads area. In addition to the software it is necessary to have a USB / RS485 converter, an adapter cable between microUSB/USB and a female connector M8 4 pin. In the Download area you can find a wiring diagram of our cable that connects Smartphone/Tablet or PC with windmeter, it takes and transforms the voltage present on the USB (Price on request). Alternatively, it is possible to use other cables with external power supply (9V battery).
