4 Material specifications of components
Prior to installation, ensure whether the wetted components are suitable for the medium to be measured!
Components Materials Mediums contacting
Electrodes Stainless steel 316 SS Yes
Process connections Stainless steel 316 SS Yes
Pipe PEEK Victrex 450GL30 Yes
Gasket EPDM Yes
Housing Aluminium pressure diecasted No
5 Suitable liquids (medium)
Liquids with a minimum conductivity of 50 μS/cm are suitable as the medium. Always ensure whether the
material of the flow sensor is suitable for the medium to be measured.
6 Installation of the flow sensor
6.1 Mechanical installation
• Protect the flow sensor against external magnetic fields in the immediate vicinity, as these can impair device
functioning (see Fig. 2).
Fig. 2:
No external magnetic fields in the
immediate vicinity of the MFS
• The sensor can be installed at any position in the pipe system. Straight pipe sections are recommended
because the flow velocity may vary in bends (see Fig. 3).
