Tips for correct sensor location

•
Turbulence generally occurs after pipe bends, branches,
dampers and fans and at cross-sections. This turbulence only
settles down after a lengthy distance. Only conduct
measurements in areas of low turbulence.
•
Always carry out measurement in the centre of the duct.
•
The optimum placement for the sensor is after filters and
rectifiers (no turbulence).
•
Place sensors before diffusers and pipe contractions.
•
Select the direction of flow onto the instrument from the straight
handle side when calibrating.
