3.2 Operating pressure of the measured fluid
As electromagnetic flowmeters have been designed for the maximum permitted operating pressure
PS in excess of 0.5 bar, they are, in reference to the Directive of the European Parliament and
Council No 97/23/ES considered pressure equipment and as such assigned to pressure equipment
categories 0 (SEP*), I, II or III.
Comment: * Sound Established Procedure
To select the correct rated pressure of the sensor flanges, the following parameters should be
considered:
• Maximum operating pressure of the measured fluid, PS;
• Rated inner diameter (DN) of the connected piping;
• Maximum temperature of the measured fluid, TS.
Standard sensor design
Operating pressure of flanged sensors according to standard EN 1092-1; material: carbon steel
Comments: * applicable to flanges made of materials of class 3E0 according to EN1092-1, such as steel
P245GH or P265GH
** available on special request for sensor sizes in excess of DN300
