The FD613 Series flowmeter
employs advanced trans-phase
measuring technology, providing
accurate and reliable flow velocity
assessments in closed piping
systems. The series uses a
non-invasive clamp-on transducer
that is placed on the outside of a
pipe. Within seconds, the large
18 mm (0.7") LCD provides
stable flow-rate readings in feet per
second or meters per second. This
product operates on metal or plastic
pipes containing liquids with more
than 100 ppm of 100 micron
or larger suspended solids or
entrained gases.

Principle of Operation

The FD613 Series flowmeter utilizes
an advanced trans-phase measuring
technique, providing accurate,
non-invasive fluid velocity
assessment without opening the
pipe. The series uses two
piezoelectric crystals contained
within one transducer to transmit
ultrasonic energy into the fluid
stream and receive back energy
reflected off discontinuities
(suspended particles or entrained
gases) within the moving liquid.
Transformations that result from the
energy reflections are processed
and converted to a measurement

of fluid velocity by the sophisticated
software algorithm. The processor
also controls all operations of the
instrument from its ultra-efficient
battery management circuitry to
a proprietary FIR (finite impulse
response) filtration program.
