1 Sealing point to secure
the calibration switch.
2 Sealing points to secure
the circuit board cover
3 Sealing points to secure
the sensor covers for the
pressure and temperature
sensors.
4 Sealing points to secure
the terminal covers of the
inputs, outputs and inter-
faces if necessary.
These sealing points
Fig. 21/4 to secure the pulse inputs and pulse outputs are sub-
ject to national regulations (cf. WELMEC 11.1, chapter 2.7.1).
Depending on the legal situation in the respective country of
use, seals produced by legally authorized manufacturers or the
metering point operators, should be used.
If the devices are supplied with connected input and/or output
cables, seals will be provided with the manufacturing symbol as
standard. If necessary, these can be replaced in the area of ap-
plication as described above.
5.3.2.3 Sensors
Examples of how to seal the connected temperature and
pressure sensors are presented in chapters 5.2.3 and 5.2.4.
