GENERAL RECOMMENDATIONS
1. Storage for a long period:
Store the transmitter in a dry room with normal temperature and humidity.
Keep protective caps in place at electrical conduits and process connections.
2. Select the appropriate place for installation:
The location of the on-site installation should provide a minimum level of vibrations
and limitation of exposure to dust and corrosive atmospheres.
The location should also allow an easy access for setup and maintenance of the transmitter.
3. Monting position:
4. Beware of overpressure:
Please carrefully check the Maximum Working Pressure (MWP) of the transmitter.

2.5 Piping
For optimal operation and measurment, the connection to the process piping
must respect the following rules:
1. For liquid or steam monitoring, the transmitter must be installed below the process piping.
2. For gas monitoring, the transmitter must be installed above the process piping.
2.5.1 Dierential pressure and ow transmitters (model FKC)
Check the high and low pressure sise on the transmitter:
Remove the protective cap:
sure to remove the caps. When removing the caps, carefully protect the threaded portion and
sealing face from damage.
Connection of the transmitter to the impulse pipes:
1.
7/16-20UNF bolts, and then the impulse pipes must be connected to the manifold valve.
Tightening torque of the 7/16-20UNF bolts should be 30 to 40 Nm (3 to 4 kgf m).
2. If a manifold is not used, the impulse pipes can be directly screwed into the transmitter process
should be 30 to 40 Nm (3 to 4 kgf m).
All parts, including transmitters, valves and manifolds, to be
connected to the process line must be selected to comply with
the piping class and maximum working pressure (MWP). If the

Typical examples of process piping connections:
• Gas ow measurement
Standard process cover type.
Place the transmitter above the process piping.
If the process temperature is high,
please use condensers.
• Liquid ow measurement
Place the transmitter below the process piping.
Make piping so that gas bubbles that might be
present in the impulse pipes cannot reach the
transmitter.
• Steam ow measurement
Install two condensers at the same height near
the piping connexion. Fill the pipes between
the condensers and the transmitter with water.
