• The measuring point should be behind the regulator at a distance of at least 10x the regulator nominal size
DN or 5x the pipe nominal size DN.
• The maximum flow rate at the measuring point must not exceed 20 m/s, depending on the system conditions.
• In certain system circuits, such as gas control systems for gas motors and in gas burners, higher flow rates
than 20 m/s are also possible. Please contact us.
• The measuring line must be connected to the pipeline or to the measuring point separately, laterally or at the
top for each device (1 actuator (item 7.03); 1 gas pressure regulator (item 7.33); 1 integrated SSV (item 7.06)).
• The SSV measuring line (item 7.08) must always be connected upstream of the first shut-off valve (item 7.13)
on the outlet side in such a way
that it cannot be shut off.
