PCE Instruments WV A Air Flow Meter / Wind Direction Station

Model # WV A

Robust Air Flow Meter for fixed installation / 4 to 20 mA output for wind warning systems, building services and building automation
The Air Flow Meter was developed to measure the wind direction in the industrial environment and can be connected to data loggers, process control systems, displays.
A 4 to 20 mA signal is available as an output signal on the Air Flow Meter. It has no dead center in the north and measures the wind direction from 0 to 360 °.
In order to protect the air flow meter from external weather influences, it is protected according to IP65.
