Piping Of Direct Mount : Absolute (Fkh) And Gauge Pressure Tranmitters (Fkp) - Fuji Electric FCX-AII-V5 series Instructions Manual And Service Instructions

3.2.3 Absolute pressure (FKH) and gauge pressure transmitters (FKP)
Remove the protective cap
protective cap. Before piping, be sure to remove the cap. When
removing the cap, carefully protect the threaded portion and seal-
ing face from damage.
Connect the transmitter to impulse pipes
The piping can be connected directly to the process connection of the transmitter or via an
objects from entering.
For an absolute pressure measurement, make sure that isolating valves or manifold can
be designed for vaccum service.
Position of process connection
The position of the process connection is determined by the relationship between condition,
Follow the process position according to the process :

Recommandation for process connection
(1) Liquid measurement
Place the transmitter below the the process
pipe.
Make piping so that gas in the impulse pipe is
not delivered to the transmitter, and incorporate
gas reservoirs as required.
(2) Steam measurement
A condensate chamber must be mounted between
transmitter and process connection.
Fill the pipe between the condensate chamber and the
transmimitter with water.
The installation of a drain is necessary.
