Piping; (Fkc) - Fuji Electric FCX-AII-V5 series Instructions Manual And Service Instructions

3.2 Process piping
The piping connection must respect some rules to have an accurate measurement :
General recognitions are :
1) Transmitter must be mounted below the process piping for liquid and steam measurement.
2) Transmitter must be mounted above the process piping for gaz measurement.
CAUTION
Check of "High" and "Low" pressure sides of transmitter
The "High" Pressure side is indicated by "H" and the "Low" pres-
sure side by "L" on the cell neck
Removal the protective cap
The process connection ports of the transmitter and manifold
remove the caps. When removing the caps, carefully protect the
threaded portion and sealing face from damage.
Connect the transmitter to impulse pipes
the manifold valve. Tightening torque of 7/16-20UNF mounting bolt should be 30 to 40
Nm (3 to 4 kgf m).
(2) If a manifold is not used, the impulse pipes can directly be screwed into the transmitter.
should be used.
Position of process connection
The position of the process connection is determined by the relationship between the condi-

Main valve or manifold used for piping should be selected with the maxi-
mum pressure of the process taken into account (piping parts such as
main valve, etc. should be furnished by user). If the main valve and other
parts do not meet the rating, it may result in leakage of gas or liquid which
could lead to a hazard.
