3.3.3 Installation Orientation
The EF200 can be mounted in any direction in
the piping. An arrow on the meter body shows
the direction of flow.
For measuring liquids in vertical pipes, the
meter should be installed with an upwards flow
direction, position A, to make sure pipes are
completely flooded, avoiding partial filling (see
Fig. 5).
For horizontal pipelines, positions B, C and D
are possible (see Fig. 5). With hot piping (e.g.
steam), position C or D must be selected in
order to respect the maximum permissible
ambient temperature at the electronics.
Do not mount the flangeless model EF200W at
sizes of 100 mm or larger in position B for use
with fluids at temperatures equal to or greater
than 200 °C.
Refer to the Technical Data section for
ambient temperatures (see 6.1.6).
Caution!
For use with the Steam Dryness Fraction
Calculator option, ensure the flowmeter is
mounted in position C.

3.3.4 Pressure Measurement Points
If a pressure measuring point is installed
after the device, ensure that there is a
large enough distance between the
device and the measuring point so that
there are no negative effects on vortex
formation in the sensor.
