Flow switch installation
General installation instructions
•
Firstly, clean the pipe system in which the flow switch is to be installed and remove
any magnetic particles, e.g. welding residue.
•
The straight in- and outlet pipe (in front of and behind the flow switch) has to be at
least 5 x DN.
•
The nominal installation position of the flow switch is an “upright
standing position” in horizontal pipework.
•
The switches should only be installed in a vertical position, deviation
max. 45° (
Fig.).
•
Please contact the manufacturer if other installation positions are desired.
•
Please make sure that there are no external magnetic fields in
the immediate vicinity of the flow switch, since these can impair
device functioning (Fig.).
•
There is an arrow on the flow switch. Ensure that this arrow is
parallel with the pipe shaft and is facing in the direction of flow
during installation (Fig.).
•
Avoid to install the flow switch close to big ferromagnetic bod-
ies. Those bodies can influence the magnetic based switching
function of the VKX and can decrease the operating reliability.
•
Screw on the union nut G ¾ made of plastic with a maximum torque of 8 Nm.
Flow switches for direct installation
During flow switch installation, ensure that
the paddle does not touch the wall of the pipe
and can move freely
Ensure that the paddle rod does not bear
against the inside of the dome
