Installation 3-19
1 Gasket ring
2 Thread
3 Inner cone
4 Inner thread of spigot nut
5 O-ring inside of sensor screw connections
Using grease on the cutting ring screw joint
Prior to installation, grease the screw joint at all points shown in the image above.
Install the sensor according to DIN 3859-2.
Screw the screw joint into the welding nozzle, ball valve, or the nozzle of the tapping
saddle using a pipe wrench or an open-end wrench (width across flats: 2.2 inches (55
mm)).
Then, pull the spigot nut and gasket ring over the flow velocity sensor and insert the
sensor into the screw joint as deep as necessary (based on the application).
Next, place the gasket ring into the screw connection and tighten the spigot nut
manually. Then, to control the number of remaining turns, use a marker to mark the
spigot nut prior to tightening the nut an additional 0.5 turns.
The retaining element is an essential part of the pipe insertion sensors. It safely
secures the sensor in position and, when installed correctly, protects the sensor from
ejection.
Risk of accident!
Do not operate the sensor without the retaining element! The
gasket ring exists only for sealing purposes and does not include
any fastening capabilities.
