Overview
The
KGD-LL-502
Single-Ended
Ultrasonic
Flow
Velocity
Meter
utilizes
laser
Raman
scattering
technology
to
enhance,
collect,
process,
and
identify
characteristic
Raman
scattering
spectra
of
measured
gases.
This
enables
simultaneous
qualitative
and
quantitative
analysis
of
multiple
gas
types
with
second-level
response
times.
