Functions

Instant Wind Speed Alarm

WL-21 displays real-time wind speed value in selectable measurement units (m/s, knots, MPH, km/h). Users can set a wind speed alert limit based on local operational safety regulations. An audible and visual alarm will be triggered when the limit has been reached. Each sensor has a unique wireless address that can connect to multiple displays to notify more stakeholders on-site.

Data Logging

WL-21 captures and stores wind speed, wind direction, temperature, and air pressure measurements.

The built-in 64MB memory and exceptional battery life support up to 1 year of continuous data logging. (based on 10s logging interval, adjustable: 2s, 5s, 10s, 1min, 5 min, 10 min, 60 min)

Logged data can be easily exported to Excel format for further analysis.

Graphical Display

The large backlit LCD with a user-friendly interface clearly indicates real-time weather data in various measurement units.

Users can view hourly wind records and historical bar charts of the last 12 hours on different pages.
