Sensor Location in piping system
The optimum location in the system depends on the application
● For liquid applications the presence of excessive gas or air bubbles in the fluid may result
in erroneous measurements. Therefore, it is preferred not to install the sensor at the
highest point in the system, where gas / air bubbles will be trapped. For liquids it is
advantageous to install the sensor in low pipeline sections, at the bottom of a U-section in
the pipeline.
4.3 Use according to specifications
"Use according to specifications" covers:
● Use within technical limits.
● Consideration of liquid specifications and references.
● Consideration of specifications as to installation, commissioning and maintenance.
Do NOT:
● Use the sensors as a footboard for installation purposes.
● Change the flow meter in any way. For e.g. decomposition of material in connection with
processing, welding and use of accessories and spare parts not approved by Siemens.
Note
If the flowmeter is not used according to the specifications, the manufacturer cannot be
held responsible for any resulting damage.
4.4 Application Guidelines
Basic Requirements
● Determine pipe material and dimensions.
● Avoid vertical pipes flowing in a downward direction.
● Avoid installation of sensors on the top and bottom of horizontal pipes, if possible.
● Select a location with the longest straight run of pipe.
● Identify upstream piping configuration (elbow, reducer, etc.).
● Pipe surface should be smooth and, if necessary, free of paint.
● Avoid pressure reduction components upstream.
