Portable Flow Metering at Its Best

The TransPort PT878 owmeter is a highly versatile,
self-contained, portable transit-time system with
options and accessories to meet all your liquid
owmeasurement needs. Its compact size; lightweight,
rechargeable internal battery pack; and universal
power supply charger make it the ideal go-anywhere
owmeter.

Accurate with Two-Phase and
Perfectly Clean Liquids

The TransPort PT878’s patented Correlation Transit­Time™ digital signal processing (DSP) technique
greatly increases its signal-to-noise ratio for accurate,
drift-free ow measurement in liquids that contain
a second phase of entrained solids or gas bubbles.
The TransPort owmeter operates in these and other
dicult applications where conventional transit-time
owmeters fail.

The TransPort PT878 owmeter also accurately
measures ow rate in perfectly clean liquids containing
no “scatterers,” where Doppler-type owmeters cannot
work. The TransPort owmeter is suited for all standard
transit-time applications, plus many that would prevent
other transit-time owmeters from working.

To hold clamp-on transducers in contact with the
pipe, a variety of clamping xtures are available to
accommodate dierent pipe and transducer sizes.
These xtures use a variety of attachment methods
including chain, metal strap, Velcro® strap and
magnetic clamps.

Quick and Easy to Use

It’s possible to make your rst ow measurement within
minutes of opening the box—the TransPort owmeter
is that easy to use. Simply input the site parameters,
clamp the transducers onto the pipe, adjust the spacing,
and you’re under way. No ancillary equipment is
needed, and there’s no need to break into the pipeline.
An experienced user can make scores of dierent
measurements in a single day. The TransPort PT878
owmeter is ideal for all kinds of ow survey work.

Flow Transducers and Clamping
Fixtures

Using clamp-on transducers, the TransPort PT878
owmeter measures ow rate through metal, plastic
or even concrete-lined pipes, without penetrating the
pipewall. From ultra-pure water to corrosive and toxic
liquids, the TransPort PT878 owmeter ensures non­contaminating, leak-free measurement with drift-free
accuracy. The TransPort PT878 owmeter has no
moving parts to wear or orices to clog. It can’t be
fouled, and it requires no routine maintenance.

A wide variety of transducers are available with
dierent operating frequencies, materials of
construction, operating temperatures and sizes to meet
the requirements of rugged industrial environments.

A large, multifunction LCD presents measured data
in both alphanumeric and graphic forms. In addition,
it helps make programming easy by presenting a
software menu that walks you through data entry and
function selection.

Standard alphanumeric functions include ow
velocity, volumetric or energy ow rates, and totalized
ow in either English (U.S.) or metric units.

In graphic mode, the LCD shows both real time and
logged data. The result is a chart recording right on
the display, which is very useful for reviewing data
and observing trends while on the site.

Submersible, Rugged Electronics
Housing

Your investment in this owmeter is protected
from the day-to-day rigors of industrial usage. The
TransPort PT878 is equipped with a rubber boot that
provides protection against vibration and shock.
The completely sealed housing and ports meet IP67
requirements, so the unit will withstand submersion
in up to 3 ft (1 m) of water for limited periods of time.
It will continue to function safely even if it is dropped
in water. The complete TransPort PT878 owmeter
system ts in a compact carrying case.

Optional Energy Measurement

Built to Be Economical and Stay

The TransPort PT878 owmeter combines proven
ultrasonic ow measurement with precise RTD
temperature measurement to determine the energy
ow rate in liquid heating and cooling systems. With
this option, the TransPort owmeter comes equipped
with a built-in power supply for loop-powered
RTD temperature sensors, as well as all necessary
circuitry and software to make energy ow rate
measurements. The energy kit option includes two
matched Pt1000 surface mount RTDs with 30 feet of
cable to plug into the PT878,

Optional Pipe Wall Thickness Gauge
Transducer

Pipe wall thickness is a critical parameter used
by the TransPort owmeter for clamp-on ow
measurements. The thickness-gauge option allows
accurate wall thickness measurement from outside
the pipe.

Infrared Port

The TransPort PT878 contains an infrared port
for communication with your PC. If your laptop or
desktop PC does not have infrared capability, an
adapter is available that can be plugged into your
PC’s serial port.

Optional Infrared Thermal Printer

Economical

To be of real value, a portable owmeter must be as
economical to own and operate as it is capable in the
eld. The TransPort PT878 owmeter is built to stay
in service for many years. Completely solid state, the
device rarely wears out or needs servicing, resulting in
little downtime and low maintenance costs.

The TransPort PT878 Flowmeter Uses
the Transit-Time Flow Measurement
Technique

In this method, two transducers serve as both
ultrasonic-signal generators and receivers.
When mounted on a pipe, they are in acoustic
communication with each other, meaning that the
second transducer can receive ultrasonic signals
transmitted by the rst transducer and vice versa.

In operation, each transducer functions as a
transmitter, generating a certain number of acoustic
pulses, and then as a receiver for an identical number
of pulses.

The time interval between transmission and reception
of the ultrasonic signals is measured in both
directions. When the liquid in the pipe is not owing,
the transit-time downstream equals the transit-time
upstream. When the liquid is owing, the transit-time
downstream is less than the transit-time upstream.

and Accessories

When you need a permanent record of your work,
live measurements, logged data and site parameters
can be sent to a variety of printers by beaming data
directly from the TransPort PT878’s infrared port. A
compact, lightweight, hand-held, infrared thermal
printer is available. This printer is powered by a
lithium ion battery.

The dierence between the downstream and
upstream transit times is proportional to the velocity
of the owing liquid, and its sign indicates the
direction of ow.
