  • Precision measurement of gas velocity and volumetric flow rate
    Patent number: 7509854
    Abstract: Systems and methods are provided for precise measurement of volumetric flow within an emissions source. A general rotation element is rotatable by an operator relative to the emissions source about an axis. A precision rotation element is rotatable by an operator relative to the general rotation element from a first position ninety degrees about the axis to a second position. A conduit receives a probe. The conduit is rotatable with the precision rotation element about the axis.
