Windmeter - Digital Anemometer

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.

• 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
