Apex Instruments, Inc.

- Model SK-3D52 - 3D Flow Measurement System



The Apex Instruments MC-3D52 3-D Flow Measurement Console and System is used in conjunction with the 3-D Pitot 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 2F (the determination of stack gas velocity and volumetric flow rate with three-dimensional probes). This console features stable and reliable differential pressure transducers for the most demanding of stack testing conditions. A convenient blowback pump, quick connects, temperature display and all voltage outputs are available for easy connection to your data acquisition system.
