A. Ajuiɛɛr:
YG-JTDL15 type tunnel ultrasonic wind speed wind direction detector is specially designed and manufactured for tunnel online monitoring wind speed and wind direction, using ultrasonic time difference method, putting two ultrasonic probes separately on the tunnel's two sides wall, when the tunnel's air flow passes between two ultrasonic probes, the ultrasonic through the sending beam and return time difference thus obtaining the tunnel's wind speed and wind direction value, because the sampling area across the whole tunnel, so the wind speed detected has a true representation.

Aluminium body, surface solar treatment, adapt to the harsh environment in the tunnel. Aluminium body, surface solar treatment, adapt to the harsh environment in the tunnel. Aluminium body, surface solar treatment, adapt to the harsh environment in the tunnel.
Sampling zone across tunnel inner lane, more real reaction to the tunnel gas flow speed. Sampling zone across tunnel inner lane, more real reaction to the tunnel gas flow speed. Sampling zone across tunnel inner lane, more real reaction to the tunnel gas flow speed.
