sun protection.
Avoid installation sites susceptible to cavitation, such as immediately behind a control
valve.
Install flow meter far removed from motors, transformers or other transmitters.
If the plan calls for installing two sensors of the same kind back-to-back, use a
customized design. Contact the responsible Siemens sales organization.
Operate the flow meter below an elevation of 2000 m above sea level.
If possible, avoid installing the flow meter at the end of a downpipe.
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
prevent 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
sensor 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 account. For highest density accuracy it is recommended to avoid sensor
orientations different to horizontal or vertical 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
piping. 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.
