Calibration Wind Tunnels

GDJ Inc. Calibration Flotek Wind tunnels are currently in use at many of the top
Calibration Companies.

The Flotek 360 and 1440 both have excellent Flow Qualities with a turbulence of
less that 0.01% in the test section.

A very tightly controlled motor speed and test Section Velocity are provided by
the use of State of the Art ABB ACS 355 & 550 VFD Motor Drives which are Torque
Sensing this allows for a very tightly controlled motor speed.
The MKS Pressure transducer provides a test section Velocity Reading with less
than 0.01% error.

The National Instruments LabVIEW Data Screen Allows for computer control of
the system and for graphing of the test in progress. Closed loop control of the test
section Velocity is provided.
