2.3.2 FREE STREAM INSTALLATION - FLANGED FITTING
Conditions:
Flow: 0.3 to 0.5m/s (at the transducer)
Viscosity limit: Up to 20 000cP
Temperature: -50°C to 200°C
Note that the thermal mass of the flanges may affect the response time of the transducer
to temperature changes.
The view shown below is schematic to show the dimensions of the side pocket, which is
fabricated by the end user.
The pocket can be fabricated with 2” schedule 40, 80 or 160 tube without affecting the
calibration.
Counter bore the pocket to a minimum depth of 13mm and diameter 52.6 ±0.1mm to
locate the 7828 centrally.
Weld neck or slip-on flanges may be used, according to the flange rating selected.
However, for higher rated flanges, only slip-on flanges may give the necessary
clearances.
