Orientation

Vertical:
Recommended orientation with upward direction of flow (View 1). When fluid is not flow-
ing, 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.
Fig. 6: Orientation Promass E
Horizontal:
The measuring tubes of Promass E must be horizontal and beside each other. When
installation is correct the transmitter housing is above or below the pipe (Views 2, 3).
Always avoid having the transmitter housing in the same horizontal plane as the pipe.
Caution:
The measuring tubes of Promass E are slightly curved. The position of the sensor, there-
fore, has to be matched to the fluid properties when the sensor is installed horizontally
(Fig. 7).
