Loosen the two nuts at the ends of the metering tube. Press the tube slightly to the top into the headpiece.

Safety flow meters S-SM
This procedure has to be carried out very carefully. You should only do it yourself, if you are sure,
you are able to cope with it. We recommend sending the flow meter back to the manufacturer.
Screw one of the end pieces out of the flow meter while holding the flow meter in a direction preventing the
metering tube from slipping out. The metering tube can now be taken out.
When mounting the new metering tube the metering and the protection glass have to fit correctly into the
O-rings and end pieces!
