many fluids with entrained solids
and gas bubbles. To extend the
benefits of the transit-time

The TransPort 2PT868

two-channel model for flow
applications requiring two simultaneous flow measurements with
one meter. The two measurement points can be on different
pipes, or at two locations on the
same pipe. Either clamp-on or
wetted transducers can be
used at either location. The dualchannel TransPort flowmeter
can also be set-up for two-path

No matter how it’s used, this

With over 20
years experience in ultrasonic
flow measurement, Panametrics
has what you need for virtually
any flow measurement application. The TransPort flowmeter
can be used with all Panametrics
ultrasonic liquid flow transducers,
clamping fixtures and flowcells.
A wide variety of clampon and wetted transducers are
available with different operating frequencies, materials of
construction, operating temperatures, sizes, area classifications
(standard or hazardous), and
operating principles (e.g., shear
wave and longitudinal wave) to
meet your requirements.
To hold clamp-on transducers in contact with the pipe,
a variety of clamping fixtures are
available to accommodate
different pipe and transducer
sizes, and the desired fixture
attachment method (e.g.,
chain; metal strap; VELCRO
®
straps; and magnetic, bolt-on,
or weldable steel yoke with
metal banding). Our universal
clamping fixture includes ruled
slide-tracks to simplify transducer
spacing for accurate flow measurements. There’s even a special
small-pipe clamping fixture with
miniaturized transducers to
simplify the flow measurements
on
1
/2- to 2-inch lines.
The TransPort PT868 flowmeter can also be used with
flowcells or spool-pieces—
precision-machined pipe sections with wetted transducers
already in place—for improved
accuracy or special situations
such as flow measurement in
very small tubing (e.g.,
1

For wetted transducer accuracy
with portability, Pan-Adapta

precision-machined pipe plugs
can be threaded into pipe
couplings or tees, letting you
install and remove wetted transducers without interrupting the
process or emptying the pipe.

Panametrics for use with other
liquid systems.
Every TransPort flowmeter
comes equipped with a built-in
16-V supply for loop-powered
RTD temperature sensors, as well
as all necessary circuitry and
software to make energy flow

offers a variety of optional components. These include clampon and wetted RTD temperature
sensors and a dual RTD transmitter that directs loop power
from the TransPort flowmeter to
the RTDs. This transmitter accepts
raw RTD inputs and provides
4- to 20-mA temperature inputs
back to the TransPort flowmeter.
These components can be

Pipe-wall thickness is a critical parameter
used by the TransPort flowmeter
for clamp-on flow measurements. The more accurately the
pipe-wall thickness is known, the
more accurate the flow measurements can be. Panametrics
offers a thickness gage option
that allows accurate wall thickness measurement from outside
the pipe. The thickness gage
option includes an ultrasonic
thickness transducer, transducer
cable, metric or nonmetric
calibration block, and a bottle
of transducer couplant.
Just plug the thickness
transducer cable into the flow
transducer inputs and you are
ready to make wall thickness
measurements. Enter a pipe
material into the TransPort flowmeter, spread a small amount
of couplant onto the pipe, place
the tip of the transducer on the
pipe surface, and the TransPort
flowmeter automatically displays
the wall thickness. It’s that easy!

The TransPort Flowmeter
Offers Two Modes To Ensure
Accurate Measurements.
The TransPort Flowmeter is the
only ultrasonic flowmeter
available with two measurement technologies built-in
so you can measure flow in
fluids from ultraclean water
to aerated liquids, oil-watersand mixtures, and even
raw sewage.
The transit-time technique uses a pair of transducers with each transducer sending and receiving
coded ultrasonic signals
through the fluid. When the
fluid is flowing, signal transit
time in the downstream
direction is shorter than in
the upstream direction; the
difference between these
transit times is proportional
to the flow velocity. The TransPort flowmeter measures
this time difference and uses
programmed pipe param-
TransFlection flow
measurement technique.
eters to determine flow
rate and direction.
The TransFlection technique also uses two ultrasonic transducers, but that’s
where the similarity to the
transit-time technique ends.
TransFlection mode uses one
transducer to shoot thousands of grouped ultrasonic
pulses in very rapid succession. The pulses bounce off
scatterers in the fluid (bubbles, solids, or liquid droplets)
and are received by the
other transducer. Each received pulse group represents a “snapshot” of the flow.
By comparing all snapshots,
objects that do not “appear”
to move with the flow are
averaged out of the measurement of the TransPort
flowmeter then determines
flow rate and direction by
analyzing the movement
of the remaining objects in
successive snapshots.
