The current-carrying capacity of theinstrument is about twice that of the above mentionedtype. 6th» Since there are two exactly similarthermocouples in series a greater deflection is producedfor a given value of current through the heatingelements. 7th. Owing to characteristics 5 and 6, therange of velocities covered by this type of instrumentis necessarily broader and the measurements are moreconveniently made. 278 FIGURES i and THE ANEMOMETER GALIERATIHG ARM.
