1. Introduction
The WindSonic4 is a two-dimensional ultrasonic anemometer for measuring wind speed and
wind direction. It provides an alternative to traditional mechanical cup and vane or propeller and
vane anemometers. Unlike mechanical anemometers, the WindSonic4 has no moving parts that
need to be periodically replaced—minimizing routine maintenance costs.
The WindSonic4 outputs an SDI-12 signal.

2. Precautions
l
READ AND UNDERSTAND the
(p. iii) section at the front of this manual.
l
The WindSonic4 is not recommended for conditions where rime, ice, or horizontal snow
will occur. It is not heated.
l
The WindSonic4 is a precision instrument. Please handle it with care.
l
If the WindSonic4 is to be installed at heights over 2 m (6 ft), be familiar with tower safety
and follow safe tower climbing procedures.
l
DANGER—Use extreme care when working near overhead electrical wires. Check for
overhead wires before mounting the WindSonic4 or before raising a tower.
l
The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for
its resistance to temperature extremes, moisture, and UV degradation. However, this jacket
will support combustion in air. It is rated as slow burning when tested according to U.L. 94
H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
