Performing flow velocity measurement with vane
wheel/anemometer (Option)
This option allows the flow velocity to be measured with an vane
wheel/anemometer, which is connected to the AUX input of the analyz-
er via a Smart-plus adapter.
When plugging in, the red marking on the plug must match the red
marking on the socket. The connecting plug of the impeller is plugged
into the corresponding socket of the Smart-plus-Adapter. It is necessary
to remove the cover cap of the vane wheel before measuring
There are two possibilities to measure the volume flow:
1.
The user enters the cross-section of the flow channel by entering the
cross-section shape (circle, rectangle or square) and its dimensions in
Settings.
2.
A volume flow hood is used. For this purpose, the user selects in Set-
tings ("Settings" button) as cross-sectional shape neither a circle, rec-
tangle or square, but a "funnel" - there is no need to enter dimensions.
The vane wheel/anemometer is attached to the hood (note the flow di-
rection) and the hood is placed on the inlet or outlet of the flow chan-
nel.
