10.2 Gaskets
Some device designs are shipped with special gaskets. These gaskets must be used and
installed properly to prevent leakage and ensure 3A and EHEDG conformity.
For all other device designs, use commercially available gaskets made from a compatible
material for the fluid and prevailing temperature (rubber, PDFE, lt, EPDM, silicon, Viton, etc.) or
use 3A-compliant gasket material for HygienicMaster devices.
Important
A wafer type sensor is installed without gaskets directly in the pipeline.
10.3 Replacing the transmitter or sensor
Important (Notice)
When replacing the transmitter or flowmeter sensor make sure that they are assigned
correctly. It is not possible to operate a flowmeter sensor of the 300 series with a transmitter of
the 500 series.
The series (e.g., ProcessMaster 300 or ProcessMaster 500) is shown on the name plate of the
transmitter or flowmeter sensor.
