Standard installation types: short-stem metersTable 1-1:
Installation type: Free stream T-Piece
Flow-through
chamber
Meter placement Meter tines are
inserted directly into
the main fluid flow.
The meter must always
be installed
horizontally and with
the tines oriented to
allow flow through or
between the gap of
the tines.
Meter tines are
contained in a side
pocket off the main
flow. The meter must
always be installed
horizontally and with
the tines oriented to
allow flow through or
between the gap of
the tines.
Meter tines are
contained in a flow-
through chamber in
which fluid is
circulated from the
main flow.
Flow rate 0.3 to 0.5 m/s (at the
meter)
0.5 to 3 m/s (at main
pipe wall)
10 to 30 l/min
Viscosity Up to 500 cP Up to 100 cP (250 cP in
some cases)
Up to 500 cP
