Determination Of The Installation Point - Beko FS109 Instructions D'installation Et De Fonctionnement

Determination of the installation point

6 Determination of the installation point
In order to keep the accuracies indicated in the data sheets the sensor has to be positioned centrally into a
straight piece of pipe at a place with undisturbed flow course.
A welded nozzle with ball valve is required for a mounting under pressure.

The mounting procedure is explained by means of the indicated pipe model.
The following connection is required for mounting:
Ball valve
G½" for the connection of FS109
DN 15
Passage ball valve minimum [15mm
An undisturbed flow course is granted if there is a sufficiently long section in
front of the sensor (inlet section L1) and behind the sensor (outlet section
L2) which is absolutely straight, without any edges, seams, bends and so
on.
The design of the outlet section has also to be observed carefully since
disturbance points cause turbulences which not only are effective towards
the air flow but also contrary to the flow direction. Details can be taken from
the table in chapter 7
BEKO supplies measuring sections for FS109 Flowsensors on request (see
page 15)
The sensor has to be inserted centrally into a straight piece of pipe.
