5. MAINTENANCE

CAUTION

• The lining of sanitary type uses fluorocarbon

PFA. For the property of fluorocarbon PFA, it is
possible that the adapter mounting screws may
loosen as time passes, so retighten them
regularly.

• Be sure to retighten the adapter mounting

screws according to the prescribed torque
values in Table 5.3.1 or Table 5.3.2. Retighten
them diagonally with the same torque values,
step by step up to the prescribed torque value.

• In case of leakage from adapter connection

point, retighten the adapter mounting screws. If
leakage doesn’t stop even if they are retight-
ened, replace the gasket between mini-flange
of flowmeter and adapter.

• It is recommended to replace the gasket

periodically,

• It is necessary to decide the period between

changes with consideration for the frequency of
cleaning cycles, the cleaning temperature and
the fluid temperature.

• Use the gasket specified by Yokogawa in Table

5.3.3
