FEP630, FEH630 ELECTROMAGNETIC FLOWMETER | OI/FEP630/FEH630-EN REV. D 17Electrode axis1 Electrode axisFigure 12: Orientation of the electrode axisThe flowmeter sensor should be mounted in the piping in such amanner that the electrode axis is oriented as horizontally aspossible.A maximum deviation of 45° from the horizontal position ispermissible.Mounting positionFigure 13: Mounting positionA Vertical installation for measuring abrasive materials,preferably with flow in upward direction.B For a horizontal installation, the meter tube must always becompletely filled with the measuring medium.Provide for a slight incline of the connection for degassing.NoteFor hygienic applications, the vertical mounting position ispreferred.For a horizontal mounting position, make sure that the sensor isinstalled to be self-draining.Minimum spacing of the devicesSpacing D: ≥ 1.0 m (3.3 ft) for Design Level ‘A’,≥ 0.7 m (2.3 ft) for Design Level ‘B’G12063HygienicMaster xxxFEHDSpacing D: ≥ 1.0 m (≥ 3.3 ft)Figure 14: Minimum spacing• In order to prevent the devices from interfering with eachother, a minimum distance as presented in Minimum spacingof the devices must be maintained between the devices.• The sensor must not be operated in the vicinity of powerfulelectromagnetic fields, e.g., motors, pumps, transformers,etc. A minimum spacing of approx. 1 m (3.28 ft) must bemaintained.• For installation on or to steel parts (e.g. steel brackets), aminimum spacing of 100 mm (3.94 in) must be maintained.These values have been calculated on the basis of IEC 801-2or IEC TC77B
