Accurate measurementThe triangular design in the WMT50 solves the mechanical shading of transducers on measurement paths. This ensures accurate wind measurement from all wind directions, without blind angles or corrupted readings.The WMT50 is free from problems the conventional mechanical sensors often have such as inertia, friction, time-constant, over-speeding, and starting threshold.
Flexible output optionsThe WMT50 communicates with the host via a bi-directional serial line. It offers a choice of four configurable serial interfaces: SDI-12, RS-232, RS-485, and RS-422. The screw terminals inside the lower part of the transmitter are easy to access.
