With a 50:1 turndown, the
TVA steam flow meter from
Spirax Sarco is a springloaded
inline variable area
meter that provides accurate
measurements down to
1/50th of its maximum flow
rate, ensuring all steam
energy consumption can be
accounted for.

The TVA is said to bring
advantages, particularly when
used in monitoring and
targeting schemes that can
create significant energy
savings, but which depend on
accurate measurement across
all flow rates.

Just six pipe diameters of
straight pipe upstream and
three downstream are
required for a smooth steam
flow into the meter to ensure
measurement accuracy.

Consequently, the meter can
be installed without the need
for costly pipe modifications.

Installation is quick and
easy. The meter is a standalone
unit that integrates
flow sensing device,
temperature sensor,
connection accessories and
flow computer into a
compact unit, eliminating the
need for additional external
equipment. Spirax Sarco says
that it can be installed in
about half the time taken to
install a meter with separate
components.

The TVA uses a profiled
stainless steel cone with a
large, smooth surface area
plated in hard chromium to
resist erosion from wet
steam, for a long and reliable
operational life with
recalibration rarely needed.

The meter is available with
a choice of 4-20mA and
pulse outputs for easy
integration with energy
management
or control
systems.
