Selecting the Right Flow Sensor

The following pictures are guidelines for correct installation of air velocity trans-

mitters.

Reliable measure-

ments can be made

by positioning the

transmitter after fil-

ters (clean rooms),

air heaters or air

coolers, where the

turbulence is very

low.

The probe shall be

installed in the

middle of the duct.

Preferred location

after filters, recti-

fiers, coolers

(no turbulances)

The probe shall be

placed in front of dif-

fusers or confusers.

Filters and coolers

calm down the air

flow.
