A Recommended orientation with upward flow direction
B Non-recommended installation range with horizontal orientation (60°)
C Recommended installation range max. 120°
Vertical
Recommended orientation with upward flow direction (view A) With this orientation,
entrained solids sink and gases rise away from the sensor area when the medium is not
flowing. In addition, the pipe can be completely drained and protected against the buildup
of deposits.
Horizontal
In the recommended installation range with a horizontal orientation (View B), gas and air
accumulations at the top of the pipe and inteference from deposit buildup at the bottom of
the pipe can influence the measurement to a lesser degree.
Inlet and outlet runs
If possible, install the sensors upstream of assemblies such as valves, T-pieces, elbows, and
pumps. If this is not possible, the specified measurement accuracy of the measuring device
is achieved by observing the specified minimum inlet and outlet runs with optimum sensor
configuration. If there are several flow obstructions, the longest specified inlet run must be
taken into account.
Inlet and outlet runs with FlowDC
Shorter inlet and outlet runs are possible with the following device versions:
Two-path measurement with 2 sensor sets (order code for "Mounting type", option A2
"Clamp-on, 2-channel, 2-sensor sets") and FlowDC
