Operating conditions: installation

Mounting location
Correct flow measurement is possible only if the pipe is full. It is preferable to install the sensors in a riser.
Note!
Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors.
For this reason, avoid the following mounting locations:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream of a free pipe outlet in a vertical pipe. Risk of partial pipe filling.
Orientation
Vertical
Recommended orientation with upward direction of flow (View A). With this orientation, entrained solids will
sink and gases will rise away from the sensor when the fluid is stagnant. The piping can be completely drained
and protected against solids buildup.
Horizontal
In the recommended installation range in a horizontal installation position (View B), gas and air collections at
the pipe cover and problematic deposits at the bottom of the pipe have a smaller influence on measurement.
