The Apex Instruments 3-D Console (MC-3D52)

The 3-D Console is used in conjunction with the 3-D Probe to determine velocity pressure and the yaw and pitch angles of the flow velocity vector in a stack or duct according to the new USEPA Method 2F. The 3-D Directional Probe is capable of measuring yaw and pitch of non-uniform flows. The yaw angle is determined directly by rotating the probe to null the pressure across a pair of symmetrically placed ports on the probe head. The yaw angle is measured with a remote inclinometer attached to the probe extension and digitally displayed on the console. The pitch angle is calculated using probe specific calibration curves. The average gas volumetric flow rate in the stack or duct is then determined from the average axial velocity.

The MC-3D52 Console features differential pressure Transducers that are exceptionally stable and reliable. The Transducers are NIST certified to ± 0.5% accuracy. The pressure transducers can withstand extreme overpressure for the most demanding stack testing conditions. There is also a convenient purge pump, quick connects, temperature display, and all voltage outputs are available for easy connection to your Data Acquisition System.
