8. Identify the upstream and downstream transducer assemblies.
For Standard Velocity Range applications, the upstream and downstream nozzle designations are interchangeable.
The system is bi-directional.
For
Extended Velocity Range applications, the system is not bi-directional. Note which valve is designated upstream
and downstream on the pipe. Identify the upstream and downstream insertion mechanism assemblies. The
downstream assembly is labeled with an alignment mark on the Barrel flange , and an associated scribe line on the
transducer tube near the connector end (see the figure below).
The downstream transducer head is angled 6° and must face into the flow.
9. Proceed with either the upstream or downstream assembly.
