1)
Exceptions:
→  18,  41
C Horizontal orientation, transmitter at
bottom
A0015590
2)
Exceptions:
→  18,  41
D Horizontal orientation, transmitter at
side

→  41
3)
1) Applications with low process temperatures may decrease the ambient temperature. To maintain the
minimum ambient temperature for the transmitter, this orientation is recommended.
2) Applications with high process temperatures may increase the ambient temperature. To maintain the
maximum ambient temperature for the transmitter, this orientation is recommended.
3) Not recommended for inhomogeneous media.

 18 Orientation of sensor with curved measuring tube
1 Avoid this orientation for fluids with entrained solids: Risk of solids accumulating.
2 Avoid this orientation for outgassing fluids: Risk of gas accumulating.
Inlet and outlet runs No special precautions need to be taken for fittings which create turbulence, such as valves, elbows
or T-pieces, as long as no cavitation occurs →  47.
Special mounting
instructions
Drainability
The measuring tubes can be completely drained and protected against solids build-up in vertical
orientation.
Rupture disk
The position of the rupture disk is indicated on a sticker beside it.
The transportation guard must be removed.
The existing connecting nozzles are not intended for the purpose of rinsing or pressure monitoring,
but instead serve as the mounting location for the rupture disk.
In the event of a failure of the rupture disk, a discharge device can be screwed onto the internal
thread of the rupture disk in order to drain off any escaping medium.
