XC-3D55 Flow Measurement Console

XC-3D55 Flow Measurement Console

The Apex Instruments XC-3D55 Flow Measurement Console is used in conjunction with various pitots to determine velocity pressure, and the yaw and pitch angles of the flow velocity vector in a stack or duct according to U.S. EPA Method 2, 2F or 2G (the determination of stack gas velocity and volumetric flow rate with three-dimensional probes).

The XC-3D55 console easily interfaces with the UINC-3D-__ Umbilical/Inclinometer Assembly through a series of 1/4-inch quick connects, a 4-pin circular connector and a type-K thermocouple jack. Readings for stack temperature, velocity pressure, pitch pressure, and yaw angle are displayed respectively through a display, process meters and a totalizer.  The null angle is displayed through a magnehelic.
