Installation
4.4.4 Sample tubes installation
• Sample inlet connections - 6 mm (or ¼'') in polyethylene or PTFE or FEP. If particulate
matter is present in the sample, pre-filtration is necessary. A filter should be inserted in the
sample line. One is available as an option. Use new pipes for all connections during
installation.
• Flow rate - 6 to 9 L/hour
• Pressure - 0.2 to 6 bars (8 to 100 psig)
• Sample acidity - Sample acidity should not be more than 300 ppm CaCO
3
• Temperature - Temperature must be between 5 to 45 °C
Note: For continuous monitoring of sample with a temperature between 5-10°C it is recommended that the
installation should include a static heat-exchanger system (see Accessories - Options - Maintenance kits on
page 107 for a list of part numbers).
At this stage of the installation, make sure that the flow valve is closed.
Connect the pipes by inserting them into the quick release connections found under the
sampling block.
Be sure that the sample line is correctly flushed before any connection to avoid particle injection
into the 9245 hydraulic system.
