• Before installing the IAS™ Sampler, unpack and carefully inspect to ensure that it was not damaged during
transit.
• The IAS™ Sampler is normally shipped with a PRV spring per the pressure range of the application. Ensure the
PRV is set to 50 to 100 psi above the maximum operating pressure as per instructions on page 11. Refer to
Table 3-1 to ensure provided spring matches line pressure.
• The IAS™ Sampler should be installed per KAM recommendations, including the mixing requirement calculated
per customer provided flow conditions.
• At the time of installation, the pipeline pressure needs to be reduced to under 100 psi or use a KAM
®
IT™
Insertion Tool where line pressure exceeds 100 psi in order to be able to install the IAS™ Sampler.
• The IAS™ Sampler Probe should be inserted so that the middle of the sampling window is approximately in the
center half area of the pipe per API MPMS Chapter 8.2 guidelines. FIG. 3-1.
• For insertable/retractable models, before mounting the IAS™ Sampler on the Full-Opening Ball Valve, determine
the insertion length required per procedure on page 7. The Full-Opening Ball Valve is used to isolate the IAS™
Sampler from the pipeline during installation or removal. The Seal Housing of the IAS™ Sampler allows the
Sampler Probe to be inserted in and out of the pipe under pressure and flow conditions up to 100 psi. It is the
user's responsibility to ensure that the IAS™ Sampler is placed in the most representative point in the flow
profile.
