Monitor location
Procedure
To achieve best sensitivity, the Rosemount SAM42 should be installed
downstream from and as close as possible to a 90° bend and not
further away than 75 cm. Care should be taken to avoid installation
near known sources of unwanted noise such as choke valves or
cyclonic de-sanding equipment. Excessive levels of unwanted noise
may compromise the measurement principle. See Figure 3-3.
