Orientation

Make sure that the direction of the arrow on the nameplate of the sensor matches the
direction of flow (direction in which the fluid flows through the pipe).
Orientation Promass A
Vertical:
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.
The measuring tubes can be completely drained and protected against solids build-up.
Horizontal:
When installation is correct the transmitter housing is above or below the pipe. This
arrangement means that no gas or solid deposits can accumulate in the curved
measuring tube (single-tube system).
Do not install the sensor in such a way that it is suspended in the pipe, in other words
without support or attachment. This is to avoid excessive strain at the process
connection. The base plate of the sensor housing is designed for mounting on a
tabletop, wall or post.
