Earthing disks are supplied in two versions:

Metallic, disk in stainless steel EN 1.4404 (AISI 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.

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 wafer 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.

It is recommended to clean the electrodes in installations where build ups or appreciable

sedimentations can occur.

Cleaning can be done using liquid detergents and medium hard brushes.
