The Walker 5002 system combines a modern ultrasonic wind speed and

direction vane with weather reporting sensors.

The ultrasonic wind vane gives high accuracy with no moving parts to

wear out. Combined in a robust package to report air temperature,

humidity and barometric pressure. This can be enhanced with the

optional water temperature sensor.

The sensor connects directly to the standard Walker DIN 144 wind

speed & direction indicator (P1249) and weather indicator (P1255).
