  • Portable apparatus for testing or calibration of a particulate emission monitor
    Patent number: 10539494
    Abstract: A particulate matter emission monitor for monitoring concentration of particulate matter concentration in a fluent stream passing through an industrial stack is tested and/or calibrated using apparatus which is scaled down in size from the much larger industrial stack.

  • Automated system and method for probe measurement of stack gas flow properties
    Patent number: 7624654
    Abstract: A system and method for the automated measurement of properties related to a stack gas stream, flow velocity for example. A probe assembly (24) is introduced into a stack through a test port and operated by an automated mechanism mounted on the test port to position a sensing tip (28) at various locations within the gas stream at proper yaw angle. A framework (30, 32, 34, 36) of the automated mechanism provides bearing support for the probe assembly while allowing the probe assembly to translate on the framework along an axis but constraining the probe assembly from turning on the framework about the axis. With a gripper assembly (44) gripping the probe assembly and another gripper assembly (56) released, a linear actuator (40) can move the gripper assembly (44) along the axis to translate the probe assembly on the framework.
