2.5.3 Shut-off and equalizing
valves
As an alternative to the SAMSON valve
block, the two shut-of valves as well as the by-
pass valve/equalizing valve can also be in-
stalled as illustrated in Fig. 5.
2.5.4 Equalizing tanks
Equalizing tanks that establish a constant liq-
uid column are required when measuring
steam.
When measuring liquids, they are only
needed when the indicating unit is mounted
above the measuring point.
For gas measurements, they are required as
chambers for condensate separation when
the indicating unit is installed below the mea-
suring point.
2.5.5 Accessories for connection
The meters are delivered without screw fit-
tings (oxygen versions are protected against
contamination by four NBR blanking plugs).
Required screw fittings, sealing or vent screws
as well as screw joints with restrictions to
dampen medium-induced vibration (particu-
larly for measuring gases) must be ordered
separately.
Note!
The screw fittings and SAMSON valve blocks
with their associated order numbers are listed
in Data Sheet T 9555 EN.
