OMEGA’s state-of-the-art wind tunnel is designed to give a highly uniform flow rate over a 152 mm (6") test section. A powerful 12 amp motor with variable speed from 0 to 10,000 RPM is adjustable to give a particular flowrate by a precise motor control unit. Each wind tunnel is supplied with an NIST traceable certificate.
The uniform flowrate is determined by monitoring a highly repeatable differential pressure sensor which has
been calibrated to each individual wind tunnel as a system. Each wind tunnel is supplied with two restrictive plates for achieving optimum low flowrates. The established differential pressure measurements versus flowrates are listed from 25 to 9000 FPM. Calibration sheets are included, which makes calibrating different flow sensors simple.
The differential pressure measurement used to establish known flowrates will be affected by barometric pressure and temperature conditions during testing. Depending on the probe being calibrated, humidity may also be a factor.
OMEGA’s deluxe wind tunnel package is an environmental monitoring system that measures barometric pressure, room temperature, humidity and differential pressure. By monitoring room conditions, standard differential pressures can be converted to actual differential pressure readings to ensure accurate flowrates.
For testing different probes, a ¹⁄ NPT connection is available. An assortment of compression fittings is provided to help mount the probe under calibration.
