5. OMNI meters can be installed vertically or rotated on the bolt pattern in any
orientation. Contact Sensus with any questions.
6. No mechanical stresses should be exerted on the meter when installed in the
pipeline. The pipeline flanges must align with the meter flanges, the distance
between the flanges must match the meter body length, and the weight of the
meter must be supported evenly. Misalignment stresses can cause the meter body
or flanges to crack; thus, when the pipeline is under pressure, flooding can occur.
7. The meter must not be subjected to pressures higher than the pressure rating
printed on the data sheet. Pressures higher than the pressure rating can cause leaks
or burst the meter body.
8. Gaskets must not protrude into the pipeline or be misaligned.
9. The pipeline must be thoroughly flushed before installing the meter to prevent
damage from debris.
10. The flow direction of the meter (indicated by the arrow on the meter body) must
correspond with the flow direction in the pipeline.
11. After installation of the meter, the pipeline, strainer, and meter must be purged of
air and filled with water very slowly to prevent the meter from being damaged by
surges. Filling the pipe too rapidly can cause air and water surges, which can destroy
the meter insert.
12. The installation site should be chosen to prevent air bubbles from collecting in the
meter, and the pipeline must always be completely filled with water. Installation of a
meter at the highest point in a pipeline must be avoided.
13. The manufacturer's normal flow must not be exceeded for extended periods.
Applications with questionable water quality should be addressed with Sensus
Engineering before meter installations.
14. The meter should be protected from stones, sand, and fibrous material.
15. The meter must be protected from pressure surges.
