6.2  Impulse Piping Connection 
Examples
Figure 6.5 shows examples of typical impulse 
piping connections. Before connecting the 
transmitter to the process, study the transmitter 
installation location, the process piping layout, 
and the characteristics of the process uid 
(corrosiveness, toxicity, ammability, etc.), in order 
to make appropriate changes and additions to the 
connection congurations.
Note the following points when referring to these 
piping examples.
•  The high pressure connecting port on the 
transmitter is shown on the right (as viewed 
from the front).
•  The transmitter impulse piping connection is 
shown for a vertical impulse piping connection 
conguration in which the direction of 
connection is either upwards or downwards.
•  If the impulse line is long, bracing or supports 
should be provided to prevent vibration.
•  The impulse piping material used must 
be compatible with the process pressure, 
temperature, and other conditions.
•  A variety of process pressure tap valves (main 
valves) are available according to the type 
of connection (anged, screwed, welded), 
construction (globe, gate, or ball valve), 
temperature and pressure. Select the type of 
valve most appropriate for the application.
