Connection instructions
1- Measurement of gas pressure
The transmitter must be installed above the piping. If
the gas temperature is high, a condensate vessel must
be used, in the same way as for the steam.

3.2.2 Effective (FKG) and absolute (FKA) pressure transmitters
Remove the protective plug.
The connection mechanism is protected by a plastic plug. Do not forget to remove it before the
connecting the piping. Be careful not to damage the threads or the support of the seal.
Connecting the transmitter to the pipes.
The standard connection mechanism allows a connection to the piping.
For the measurement of absolute pressure, ensure that the shut-off valves or manifolds used
can work under vacuum.
Position of the fitting mechanism.
The pressure intake must be located as shown on the following figures for the pressure to be
transmitted correctly to the transmitter.
The position of the pressure intake is determined according to the conditions of service (measuring
point, characteristics of the process).
