Simple Calibration System

Accurate Flow measurement of Clean Fluids

from Outside Plastic or Metal Pipes

Recommended for clean fluids like water, glycol, oil and most
chemicals. Portaflow ultrasonic sensors strap-on the outside of pipes
from 1/2 to 78 (13 to 2000 mm) diameter. The ultrasonic signal
penetrates all common metal and plastic pipe materials. Sensors can
be mounted without shutting down flow and there is no obstruction or
pressure drop.

Calibration is easy with the onscreen menu system. Enter the pipe
diameter, wall thickness and pipe material, and the Portaflow indicates
the optimum mounting method and separation distance for the
sensors. Calibration parameters can be stored for up to twenty
different sites so that operators can recall calibration setups from the
Portaflow memory.

""

The Portaflow is powered by an internal, rechargeable NiMH battery or
can be operated continuously with AC power input. Use it for spot
checks or for extended operation as a 4-20mA flow transmitter. Each
Portaflow includes a carrying case, transducer set, mounting track,
cables and accessories.

Sensor Mounting

Portaflow transducers can be mounted on vertical or horizontal pipe. The pipe must
be full.

Choice of “Reflex” or “Diagonal” operating modes depends on the application and
pipe diameter. Through the calibration menu you are prompted to enter: pipe OD,
pipe wall thickness and lining thickness, pipe material, fluid type and temperature.
Once these values are entered into the calibration menu, the Portaflow indicates
the transducer mounting mode and correct sensor separation distance.

Diagonal Mode

Large Display with User-friendly Calibration Menu

Flow rate and total flow are displayed continuously along with battery status,
signal strength, plus any error messages. Press one key to instantly change the
units of flow measurement (eg. from gallons to litres). Real time flow can be
displayed in large numeric values or as a graph.

Calibration is easy with the Portaflow menu system. Use the “Quick Start” menu to enter pipe OD, wall thickness, pipe
material, fluid type and temperature. The flowmeter will prompt with the correct mounting method and sensor separation
distance and begin reading flow as soon as the sensors are mounted.

Measures, Totalizes and Transmits Flow in Directions

Forward flow is displayed on the Portaflow as a positive value and reverse flow is shown as a negative value. Separate 12­digit totals for both forward and reverse flow are also displayed. The 4-20mA output can be configured with 4mA as zero
flow, or with 4mA as a negative value and 20mA as a positive value.

In most applications Reflex mode mounting will be used for pipes 10 (250 mm)
diameter or less, and Diagonal mounting will be used for pipes greater than 10
(250 mm) diameter.

Each Portaflow includes stainless steel clamps and a guiderail for easy mounting.
Sensor separation distance can be adjusted, and sensors can be extracted and
remounted without removing the guiderail or clamps. An acoustic gel (supplied) is
used between the sensors and the outside of the pipe to ensure that sound is
conducted from the sensors through the pipe wall.

Stores Calibration Set-up for Multiple sites

Calibration data can be stored for up to 20 different sites or applications. If you regularly return to the same pipe location for
flow readings, this is a real time-saver. You can enter a site name and all your calibration parameters are automatically
saved. When you return to that pipe location, simply recall the site name/number from the set-up menu, mount the sensors
and start reading flow.

Built-in Data Logger (PT500 only)

Stores up to 98,000 data points at programmable intervals from 5 seconds to 1
hour. Scroll through stored data or view log files as a graph on the PT500
display. Use the USB or RS232 output to download log files to your PC for
analysis and printing. Log files can be saved as text files and imported into
database or spreadsheet programs like Microsoft Excel.

4-20mA Output

Connect the Portaflow to external displays, recorders, data loggers or controllers. Install sensors without cutting pipe so
you can use the Portaflow as a spare or emergency transmitter when in-line flow meters fail. The analog output can be
configured for 4-20mA or 0-20mA signal output.

Portaflow PT500

with Data Logger and Sensors

for a Wide Range of Pipe Sizes

With two pairs of Transducers, the PT500 works on a
wide range of pipe sizes from 0.51 to 78” (13 to 2000
mm) pipe diameters. It includes a 98,000 point data
logger with USB and RS232 outputs.

The simple, quick-start calibration system calculates
sensor separation distance based on pipe diameter and
pipe wall material. Flow is displayed in your choice of
engineering units. Data can be stored in selectable

mm) outside diameter pipes, or ‘B’ size for 2 to 39.4”
(50 to 1000 mm) pipes. Use it on any solid metal or
plastic pipe material.

The PT400 displays, totalizes and transmits with
isolated 4-20mA and programmable pulse outputs.
The rechargeable NiMH batteries will power the unit
for 16 hours continuous operation and charges
overnight.

It takes just a few minutes to install the Transducers and measure flow from outside the
pipe. Measure flow in volumetric units (gallons or liters) or switch to velocity units (ft/sec or
m/sec) with a single key press. Forward and reverse flow is displayed and totalized on the
large, backlit display.

Operate the PT400 or PT500 from internal NiMH batteries or continuously with the 110­240VAC charger supplied. Signal strength and battery state is displayed. Select from 9

Portaflow PT400-500 are
ideal to measure flow
rate of clean, non-aerated
fluids in full pipes. Works
best on fluids that have
less than 2% particulate
or gas bubbles.

How it Works

The PORTAFLOW is a Transit Time ultrasonic
flow meter. It measures flow by injecting sound
from a transmitting sensor, through the pipe wall
into the flowing liquid and then to a receiving
sensor. The elapsed time between transmitted
and received signals is very precisely calculated
by the flow meter.

Then the sensors trade functions. The original
receiving sensor now becomes the transmitting
sensor and the ultrasonic signal is transmitted in
the opposite direction. Again the elapsed time
between transmitted and received signals is
calculated.

The transit time in the direction of flow is faster than the transit time against the flow.
By comparing these time differences the PORTAFLOW is able to accurately calculate
the flow rate. Because the ultrasonic signal is forced to cross the pipe, an average of
the flow profile is calculated. So compensation for laminar or turbulent flow is
automatic.

The Portaflow Transit Time flow meter is designed for clean, non-aerated liquids (<2%
by volume). High concentrations of solids or gas bubbles will attenuate the ultrasonic
signal and sound will not be able to cross the pipe. A Greyline Doppler-type flow meter
is recommended for applications with solids or bubbles (eg. wastewater or slurries).
