Flowserve TRG 5-11 - Manual (Page 11)


Installation
TRG 5-11
. Provide a bore for the sensor d = 6 mm on site.
. Insert the temperature sensor
C such that its measuring tip D reaches 0 mm into liquids or
5 mm into gases, Fig. 6.
3. To fix the sensor use either a mounting flange or a gas-tight screwed socket, Fig. 8, Fig. 9.
TRG 5-41
. Provide a bore for the protective tube d = 4 mm on site.
. Unscrew the cover of the temperature sensor
C from the protection tube G, Fig. 5, Fig. 10.
3. Insert the protective tube G such that the measuring tip H reaches 00 mm into liquids or
60 mm into gases. If a short installation length is required provide an angled piece for the sensor
and ensure that the tip points against the flow direction, Fig. 13, Fig. 14.
4. Weld the protection tube in place. Use only gas-welding process  and 4 to ISO 4063.
5. Place copper ring D 8 x  onto the protection tube
G and screw the cover of the temperature
sensor C onto the protection tube. Slightly fasten the cover of the temperature sensor with an
open-end spanner.
Attention
■
Only qualified welders certified according to EN 87- may weld protective sleeves
into pressurized lines.
Tools
■
Open-end spanner 4 mm A. F.
Heat treatment of welds
A subsequent heat treatment of the welds may be required if it is specified by the plant operator.
Note
■
When installing the equipment in pipes weld an elbow J onto the pipe, ensuring that
the measuring tip points against the flow direction of the fluid, Fig. 13, Fig. 14.
■
Install the temperature sensor such that its measuring tip D/H is permanently
immersed in the fluid, Fig. 11, Fig.12.
■
Do not completely insulate the temperature sensor. See Examples of Installation,
Fig. 11, Fig. 12.
