Alicat Scientific now offers its mass
flow meters and mass flow controllers
with turndown ratio of 200:1 as
standard. This wide sensitivity range
enables OEMs and systems integrators
to achieve cost and space savings
without sacrificing performance.

Alicat meters and controllers
quickly and accurately measure mass
flow using differential pressure and a
patented laminar flow technology,
resulting in fast response with a
rugged design. The turndown ratio
of a flow instrument refers to the
ratio of minimum flow to full scale
flow that the unit can accurately
measure. The company says that
while the industry standard for this
performance parameter is 100:1 or
less, Alicat’s 200:1 ratio covers a wider
flow range with fewer pieces of
instrumentation.
