Mounting example
■
The temperature sensor instal-
lation point which is optionally
integrated in the ow sensor must
be secured.
■
Secure the sensor aer instal-
lation against unauthorised
removal with appropriate sealing
(included in accessories kit)!
■
At the versions with temperature
sensor type TS-45-5 (see type
plate at the sensor cable) both
sensors must be always immersed
directly in contact with the heat
conducting uid. The installation
in sensor pockets is not allowed.
Installation with existing immersion
sleeves
In Germany the C5 can be put into
use in connection with existing im-
mersion sleeves in accordance with
the article “Putting into use of MID
homologated temperature sensors”
released in the PTB notications 119
(2009), Edition 4. Based on current
information, the regulation has a pe-
riod of validity until 30.10.2026. For
the identication and marking of the
usable existing immersion sleeves
in connection with the C5 meter, an
identication and marking set can be
delivered from our company (order
number 137382).
■
The connecting cables may not be
buckled, extended or shortened!
■
The seal at the sensor installation
point on the ow sensor may not
be damaged.
■
Remove locking screw and seal
at the ball valve completely, if
existing.

motion.
■
Using the other end of the instal-
