3. INSTALLATION
CAUTION
• In case of standard gasket (EPDM rubber),
tighten the adapter mounting screw according
to the torque values in Table 3.3.18.
• In case that optional code GH (Silicon rubber)
is selected, tighten the adapter mounting screw
according to the torque values in Table 3.3.19.
• Tighten the adapter mounting screw in diagonal
order step by step.
• After tightening of screw, confirm that gaskets
protrude inside adapter. Protruding of gasket is
necessary to keep the sanitary requirements.

4) Mounting flowmeter to piping
Connect the flowmeter to the piping in a manner
appropriate to the ferrule, the sleeve, or the
alternative that has been welded to the adapter.
5) Confirmation of adapter mounting screw
After installation of the magnetic flowmeter, be
sure to retighten the adapter mounting screw
according to Table 3.3.18 or Table 3.3.19.
Be sure to confirm that leakage from adapter
connection point does not occur by filling the
pipe of the flowtube with fluid.
