3.2.5  Relative pressure transmitters with separator (FKB)

Absolute pressure transmitters absolute with separator (FKM)

Flange seal mechanism.

A flat seal must be installed between the flange of the separator and the flange of the tank to be 

fitted. The seal must be selected based on the type of flange fitted to the separator. Its internal 

diameter must be greater than or equal to that of the measurement membrane, so that it does 

not press on the latter, which would give a false measurement.

The standard dimensions of the membranes are as follows:

DN of the flange 

 Diameter of membrane (mm)

DN80 / 3” 

 stainless steel: 73

Quality materials: 89

DN100 / 3” 

 stainless steel: 96

Quality materials: 89

For other types of flanges, consult Fuji Electric.

Seal

Screw tightening method of the mounting flange.

Tighten the screws diagonally and in three passes using the proper tightening torque for these 

screws, according to the standard of the flange used.
