Probe Calibration Services:
Wind tunnel calibrations are performed on a variety of probes at various
flow conditions. ESC's onsite wind tunnel is audited and certified by the EPA to
perform 3-D probe calibration. Typical calibrations are performed at 60
& 90 fps velocities while moving the probe through simulated pitch angles.
Optional third velocity calibration will improve the calibration data for
lower test velocities.
All probe calibrations are performed using electronic
pressure transducers and computer data acquisition to obtain the best
representation of probe pressures.
One
Method 2F and two Method 2H calculation spreadsheets are included with each Environmental
Supply Company Three Dimensional wind tunnel probe calibration.
Method 2G: Determination of stack gas
velocity and volumetric flow rate (Wind Tunnel Calibrated S-Type Pitot with
Scribe Line)
Method 2G is a variation of
Method 2 that uses a wind tunnel calibrated Type S Pitot to determine the yaw
(side-to-side) angle of flow. Method 2G requires qualified wind tunnel
calibration of the Type S Pitot to determine the calibration coefficient of the
pitot and the yaw-null rotational offset angle of the reference scribe line. All
ESC Method 2G Type S Pitots come with a 1" oversheath, a calibrated pitot
coefficient and reference scribe line.

ESC Type S Pitots are available in several
styles and are made from 316 stainless steel or corrosion-resistant
Inconel alloy 600 for temperatures exceeding 1200°F. Sealed oversheaths
and packing glands are available. ESC is
experienced in fabricating Type S Pitots for unique applications.
