Portable Flow Metering at Its Best
The TransPort PT878 flowmeter is a highly versatile,
self-contained, portable transit-time system with
options and accessories to meet all your liquid
flowmeasurement needs. Its compact size; lightweight,
rechargeable internal battery pack; and universal
power supply charger make it the ideal go-anywhere
flowmeter.
Accurate with Two-Phase and
Perfectly Clean Liquids
The TransPort PT878’s patented Correlation Transit-
Time™ digital signal processing (DSP) technique
greatly increases its signal-to-noise ratio for accurate,
drift-free flow measurement in liquids that contain
a second phase of entrained solids or gas bubbles.
The TransPort flowmeter operates in these and other
difficult applications where conventional transit-time
flowmeters fail.
The TransPort PT878 flowmeter also accurately
measures flow rate in perfectly clean liquids containing
no “scatterers,” where Doppler-type flowmeters cannot
work. The TransPort flowmeter is suited for all standard
transit-time applications, plus many that would prevent
other transit-time flowmeters from working.
Quick and Easy to Use
It’s possible to make your first flow measurement within
minutes of opening the box—the TransPort flowmeter
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 different
measurements in a single day. The TransPort PT878
flowmeter is ideal for all kinds of flow survey work.
Flow Transducers and Clamping
Fixtures
Using clamp-on transducers, the TransPort PT878
flowmeter measures flow 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 flowmeter ensures non-
contaminating, leak-free measurement with drift-free
accuracy. The TransPort PT878 flowmeter has no
moving parts to wear or orifices to clog. It can’t be
fouled, and it requires no routine maintenance.
A wide variety of transducers are available with
different operating frequencies, materials of
construction, operating temperatures and sizes to meet
the requirements of rugged industrial environments.
To hold clamp-on transducers in contact with the
pipe, a variety of clamping fixtures are available to
accommodate different pipe and transducer sizes.
These fixtures use a variety of attachment methods
including chain, metal strap, Velcro® strap and
magnetic clamps.
Alphanumeric and Graphic Liquid
Crystal Display Completes the
Picture
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 flow
velocity, volumetric or energy flow rates, and totalized
flow 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 flowmeter 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 flowmeter
system fits in a compact carrying case.
