3.5 Mounting
3.5.1 Mounting position of the flow sensor
Installation of the flow sensor is allowed in horizontal, slightly ascending and vertical pipe
sections with up going flow direction (see next section). If installed in a horizontal or slightly
ascending pipeline, the connection box of the flow sensor has to be up or down.
3.5.2 Mounting location of the flow sensor
Observe the following precautions to avoid measuring errors or malfunctioning of the flow meter
due to gas or air inclusions or an empty pipe.
Since gas will collect at the highest point of a pipe, installation of the flowmeter at that location
should always be avoided. In long horizontal pipes the flow meter has to be installed in a slightly
ascending pipe section. If not possible, ensure adequate velocity to prevent air, gas or vapour
from collecting in the upper part of the flow tube.

WARNING!
Do not unscrew the flanged transducer construction. This will cause direct contact with the high
temperature liquid running through the flow sensor.
INFORMATION!
For proper flow measurement the measuring tube must be completely filled at all times. When
the sensors become non-wetted, a loss of signal message will be displayed. There is no damage
when this occurs.
