NOTE
For steam service, do not blow down impulse piping through the transmitter. 
Flush the lines with the blocking valves closed and refill the lines with water 
before resuming measurement.
NOTE
When the transmitter is mounted on its side, position the Coplanar process 
flange to ensure proper venting or draining. Keep drain/vent connections on 
the bottom for gas service and on the top for liquid service.
NOTE
The Rosemount 3051N transmitter incorporates two independent seals 
between the process connection and the conduit connection.
