6.2.2 Piping of pressure transmitter type : FKP
Removal of protective cap
The process connection port of the transmitter is fitted with a protective cap. Before piping,
remove the cap carefully. When removing the cap, carefully protect the threaded portion and
sealing face from damage.
Connection of transmitter and impulse pipe
• Impulse pipe should directly be screwed into the transmitter.
• After connection, close the stop valve of transmitter in order to prevent foreign materials
from entering the inside.
Position of process taps (Horizontal main process piping)
The position of the process tap is determined by the relationship between condition, charac-
teristics and measurement point of process fluid. Note the following figures when planning
and installing the piping.
