▶
When installing in a hazardous area, the separate Explosion Proof Type Manual must
be considered.
▶
Install flow meter away from magnetic compasses as it contains no precaution to pre-
vent it from causing compass deviations.
▶
Density indication of the Coriolis flow meter depends on installation orientation and
has to be corrected. For vertical and horizontal orientation (maximum deviation ± 5°)
of the sensor this can be done by the transmitter automatically if the appropriate sen-
sor orientation is selected. For other orientations (inclinations to vertical or horizontal
orientation ≥ 5°) this can not be automatically corrected and has to be taken into ac-
count. For highest density accuracy it is recommended to avoid sensor orientations
different to horizontal or vertical installation.
6.1.3 Instructions
Observe the following general installation instructions during installation:
▶
Install the flow meter avoiding shock and vibration as much as possible.
▶
Use closing valves and bypass line to facilitate zero point setting.

▶
For application involving fluids, avoid installation at highest point of piping. Formation
of gas bubbles and accumulation of gas in measuring tube may result in increased
measurement uncertainties.
▶
In case of gas measurements, avoid installation directly in front of lowest point in pip-
ing. Accumulation of fluids, such as condensate, may result in lower accuracy.
▶
Do not install immediately in front of a free pipe outlet in a downpipe.
▶
Avoid letting the sensor run idle while taking the measurement, e.g. when installed in
front of an air gap to containers in case of filling applications. Doing so may result in
incorrect measurements. To avoid this, install a restriction in the open downpipe or
use an orifice gauge with a diameter smaller than the nominal pipe width.
▶
Each device is tested for pressure prior to delivery.
