Orientation

Endress+Hauser
Make sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow
(direction of fluid flow through the pipe).
Vertical (Fig. V)
Recommended orientation with upward direction of flow. When fluid is not flowing, entrained solids
will sink down and gases will rise away from the measuring tube. Thus the measuring tubes can be
completely drained and protected against solids buildup.
Horizontal (Fig. H1 / H2)
The measuring tubes must be horizontal and beside each other. When installation is correct the
transmitter housing is above or below the pipe (Fig. H1/H2). Always avoid having the transmitter
housing in the same horizontal plane as the pipe.

= To ensure that the maximum permitted ambient temperature for the transmitter is not exceeded
we recommend the following orientation:
For fluids with low temperatures, we recommend the horizontal orientation with the transmitter head
pointing upwards (Fig. H1) or the vertical orientation (Fig. V).
When using a bent measuring tube and horizontal installation, the position of the sensor has to be
matched to the fluid properties!

Horizontal installation for sensors with a bent measuring tube
1 Not suitable for fluids with entrained solids. Risk of solids accumulating.
2 Not suitable for outgassing fluids. Risk of air accumulating.
