In operation the instrument is inverted so that the distilled water is in contact with the filter paper. The amount of [[evaporation]] that occurs during an interval of time is determined by noting the change in level of the [[meniscus]] of the water. <br/>''See'' [[Dines anemometer]], [[Pitot-tube anemometer]]; <br/>''compare'' [[Venturi tube]].</div><br/> </div>
