Velocity & Flow Calibration Rigs

Velocity & Flow Calibration Rig


The Sensing Precision Velocity & Flow Calibration Rig (VFCR) is designed for the calibration of Anemometers (both thermal and vane), Pitot tubes, Capture Hood, Yaw Probes and a variety of other small-scale aerodynamic experiments where the expense and complexity of an enclosed section of VFCR would not be justified We offer multiple solutions of our VFCRs, allowing the customer to taylor the design of the solution to their specific requirements.
