Tecfluid MX4 For FLOMID Series - Manual (Page 14)

14
Earthing disks are supplied in two versions:
METALLIC, disk in stainless steel EN 1.4404 (SS 316L), for liquids compatible with this
material.
PLASTIC, with an electrode to make the contact with the liquid. The materials (plastic and
metal) depend on the working liquid.
5.4 Tightening torque
The tightening torque for the flange bolts should not exceed 32 Nm for working pressures
of 16 bar maximum.
This tightening torque should be applied to sandwich mounting (Flomid-0FX) and also to
flange mounting sensors (FLOMID-2FX) for the same working pressure of 16 bar.
The maximum tightening torque varies in function of the nominal pressure (PN) of the
sensor.
The tightening of the bolts should be uniform, following the sequence shown in the
drawings and depending on the number of flange bolts.
6 MAINTENANCE
It is recommended to clean the electrodes in installations where incrustations or
appreciable sedimentations can occur.
Cleaning can be done using liquid detergents and medium hard brushes.
