2. INTENDED USE
2.1. Operational restrictions
2.1.1. The flow meter should be operated under the conditions of influencing
factors and parameters of the controlled medium, which do not exceed
the permissible values specified in the operating documentation.
2.1.2. The flow meter can be installed in vertical, horizontal or inclined piping.
2.1.3. Precise and reliable operation of the flow meter is ensured if the following
conditions are met at the CP installation site:
- Fluid pressure in the pipeline and its operation modes exclude gas for-
mation and/or accumulation of gas (air)
- The internal volume of PS must be filled with liquid during operation
- Sections of the pipeline up to the flow meter should not contain devices
or structural elements that cause changes in the structure of the fluid flow.
2.1.4. Type and composition of the controlled liquid (presence and concentra-
tion of suspended solids, foreign liquids, etc.), operation mode and con-
dition of the pipeline should not lead to corrosion and/or deposits that
affect the performance and metrological characteristics of the flow meter.
2.1.5. Flow meter should be installed on the site in accordance with the section
"Installation of the flow meter" of this manual.
2.1.6. Lightning protection of the device site protects the device from failure in
the presence of lightning discharges.
2.1.7. The requirements for the operating conditions and the selection of the
installation site given in these operating instructions take into account the
most typical factors affecting the operation of the flow meter.
Factors that cannot be predicted, evaluated or checked and which
the manufacturer could not consider in the development of the flow meter
may exist or occur during its operation.
If such factors occur, they must be eliminated or a different place of
operation must be found where these factors do not exist or do not affect
the operation of the product.
