Orientation
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
Recommended orientation with direction of flow upwards. 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 means that no gas bubbles
or solids deposits can form in the bent measuring tube (single-tube system).
The sensor cannot be installed suspended (i.e. without support or holder) in the pipe. This prevents excessive
material load in the area of the process connection. The base plate of the sensor housing allows bench, wall or
post mounting.
Vertical and horizontal orientation
The baseplate of the sensor housing allows for a table, wall or post mounting.
Dimensions of holes on the baseplate → ä 24.
