ZAS Doppler Sodar Wind Profiler
ZAS
The ZAS is a Doppler sodar wind profiler that measures wind speed and direction at up to 20 vertical levels between 10 m and 200 m using a piezoelectric acoustic transducer. It is supplied in the UK by MetSensor UK.

- ✓ Measurement height range 10-200 m, vertical resolution ≥10 m
- ✓ Horizontal wind range 0-30 m/s, vertical wind range -7 to +7 m/s
- ✓ Piezoelectric acoustic transducer operating principle
- ✓ Modbus RTU protocol over RS485/RS232
- ✓ Under 15 kg weight, compact radome under 50 x 50 x 27 cm

Frequently asked questions
How does a sodar wind profiler work?+
It uses acoustic (sound) pulses from a piezoelectric transducer and measures the Doppler shift of the returned echo to derive wind speed and direction at multiple heights.
How many height levels does the ZAS measure?+
Up to 20 levels between 10 m and 200 m, at a vertical resolution of 10 m or better.
What is the weight of the ZAS unit?+
Under 15 kg, with a radome under 50 x 50 x 27 cm.
What communication protocol does the ZAS use?+
Modbus RTU over RS485 or RS232, with WiFi, Bluetooth and LTE available.
