MARK II WSI
The Dwyer MARK II Wind Speed Indicator indicates wind speed directly on its liquid filled scale reading in miles per hour (0-80) and Beaufort scale (1-12). Scale calibrations show the wind speed corresponding to various fluid levels. For wind direction, observe the weather vane position. It is 100% pneumatic.

The Dwyer Mark II Wind Speed Indicator (MPH) indicates wind speed directly on its liquid filled scale reading in both miles per hour (0-80) and Beaufort scale (1-12). The instrument is 100% pneumatic, operating on the time proven principle of aircraft speed indicators. The complete kit consists of a pick up vane connected by fifty feet of flexible double column tubing to the Mark II Indicator, plus all necessary mounting hardware, fluid and instructions.
In operation, wind aligns the Mark II weather vane pointing the pick up tube into the wind. Wind pressure enters and is transmitted through plastic connecting tubing to red fluid inside the indicator. Fluid level rises and falls in response to changing wind speed. Scale calibrations on the indicator show the wind speed corresponding to various fluid levels. For wind direction, observe the weather vane position.
