INTRODUCTION
The Ultraflo 2000 is a “Clamp-on” liquid flow
meter that uses the Transit Time method of
measurement to read flow. Using two PT100
temperature probes to measure temperature it
can also be used as a Heat/Energy meter.
The Ultraflo is able to measure the flow of liquid in
any pipe from 13mm to 5000mm, providing the
pipe is flooded and the correct transducers are
used. Units are supplied according to application
data provided by the customer.
The instrument displays volumetric flow rate in
m3/hr, m3/min, m3/sec, g/min, USg/hr, l/min, l/sec
and linear velocity in metres and feet per second.
The total volume of flow will be displayed, up to a
maximum 12-digit number. When supplied as a
Heatmeter, kW, kCal/hr, MJ/hr, MJ/min and
MJ/sec can be displayed, as well as the
temperature differential.
The flowmeter is supplied with electronics,
sensors and all mounting hardware. The
Heatmeter version will also be supplied with
PT100 temperature probes.
HARDWARE
Electronics Housing
An ABS housing with an opaque door contains
the master PCB. The housing is designed for wall
mounting using the brackets provided (see Figure
2 for mounting pattern). Drilling further fixing holes
in the Housing remove the IP67 protection rating
and CE approval.
Mounting the housing into position does not
require the removal of the electronics or the front
display panel.
Figure 2
DO NOT PROVIDE POWER to the instrument
until the service compartment cover has been
replaced.
The electronics are factory set for a particular
supply voltage. Should it be necessary to change
the settings for the power supply see page 7,
Power up.
Having completed the procedure for mounting the
electronics, connecting all cables and checking
the power supply, the power can now be applied.
The Ultraflo 2000 is now ready for programming.
A full programming procedure is described on
page 7.
Before programming the instrument, it is
necessary to attach the transducers to the pipe
wall such that they can be finally locked in the
correct position based on exact data provided by
the instrument.
TRANSDUCERS
Each instrument uses two identical transducers,
which transmit and receive the ultrasonic waves.
They are clamped to the pipe surface using the
mounting hardware supplied, as described on
pages 5, 6.
The standard transducers are made from a Peek
material with an aluminium plate supporting the
stud, used to lock the sensor in position. A flying
armoured lead is attached between the sensor
block and the tuning circuit.
Figure 3 – 1MHz Sensors with TNC Coaxial
Connector
Transducers are supplied according to the pipe
size and flow velocity, and are available to meet
an operating temperature range from –20°C up to
+200°C.
Transducer Connections
Transducers are connected to the electronics
from the tuning circuit by TNC connectors. All
other output and input connections are made
through metal glands to the clearly marked
terminals.

Only one current output can be used with the flow
meter. The heatmeter option is supplied with a
separate heat integrator, please see page 29.
PT100 temperature probes should be connected
to the supplied integrator, please see page 29.
Transducer Hardware
Transducer alignment guide rails, chains and
couplant are supplied with all units in order to
ensure that the transducers are accurately aligned
with respect to the pipe axis.
A single guide rail assembly is supplied for
mounting the transducers in Reflex mode and two
guide rails are provided for mounting in Diagonal
mode.
Figure 4 – 1MHz Reflex Mounting Assembly
Figure 5 - Diagonal Beam Mounting Hardware
Transducer Mounting
The two different methods of mounting the
transducers are shown on pages 5 & 6. When
ordering the Ultraflo 2000 specific application
information should have been given. This
information determines the correct hardware to be
supplied with each instrument.
Reflex Mode
Reflex mode is a default setting on all applications
up to 215mm. Above this the instrument will
default to Diagonal mode. It is possible to change
these default settings if required (see page 11 Set
up sensors).
Before attempting to attach the transducers it is
imperative to ensure that the correct position has
been chosen to site the transducers and that the
pipe surface conditions are suitable. Go to page
17 and carefully follow all instructions for the
selecting and preparing the transducer mounting
site.
At this point program the instrument to determine
the separation distance. When you have this
information from the instrument follow the set up
procedure below.
Procedure
a) Insert the transducers into the guide rail
so the tails come out of either end.
b) By turning the locking nut centre
clockwise, withdraw the transducers up
into the guide rail.
c) Apply a bead of coupling grease to each
transducer. See page 19, figure 15.
d) Attach both lengths of chain to the quick
links provided and offer the guide rail up
to the pipe wall at 45°.
e) Wrap the chain around the pipe and
connect to the ‘J’ bolt. Complete the same
for both ends of the guide rail then tighten
the locking nuts on the ‘J’ bolt. This will
secure the complete assembly to the
pipe.
f) By turning the centre of the locking
assembly anti-clockwise lower one block
onto the pipe. Now adjust the second
block to required separation distance and
repeat the procedure. The separation
distance is measured from the front edge
of each block and not the centre of the
locking nut.
g) If the instrument now reads a negative
flow swapping the TNC connectors on the
instrument can change this.
h) Now lock the transducers in position by
tightening the nut on locking assembly.
“DO NOT USE EXCESS PRESSURE”.
Note: When moving the transducers into position
ensure that they are withdrawn into the guide rail
as far as possible. This ensures that the couplant
will not be removed from the transducer face
before it is screwed down into position.

All transducers are mounted in Reflex or Diagonal
mode as described on page 5 and 6. The guide
rail assemblies are held in position using chains.
Diagonal Beam Mode
Diagonal beam mounting means the two
transducer blocks are mounted on opposite sides
of the pipe as shown in figure 7. This is the default
setting for all applications above 215mm.
If you encounter a difficult application or the
maximum flow velocity is outside of the default
operating range, when working in the Reflex
mode, it is possible to reprogram the instrument to
operate in Diagonal mode (see page 11, Set up
Sensors)
Diagonal Set up Procedure
a) Using whatever means available mark a
reference line around the circumference
of the pipe (reference line D). As shown
in figure 7.
b) Locate and mark two positions exactly
180° apart around this reference line.
c) On both of these positions draw a
reference line (E) perpendicular to line
(D), parallel to the pipe axis and
approximately 1 metre long. See figure 7.
d) Take each of the guide rails and load the
transducers as described previously on
page 5. Only one transducer goes in each
guide rail.
d) Attach the one guide rail to the pipe using
the chain provided, such that it is parallel
to the reference line (E) and position so
that the transducer face can be aligned
with reference line (D).
e) Program the flow meter and obtain the
separation distance.
f) From the intersection of the
circumference reference line (D) and the
second reference line (E) measure and
mark the separation distance XXX. Now
mount the second guide rail such that the
transducer face can be positioned on this
intersection ensuring that the guide rail is
parallel to the reference line (E). See
figure 7.
g) Screw down both of the transducers and
lock in position as previously described.
h) RG223 Coaxial Cable (50ohm), Different
lengths up to 200 metres available on
request.
Figure 7
HINT: DRAWING A TRUE CIRCUMFERENCE
AROUND A PIPE
An easy way to draw a perpendicular
circumference around a large pipe is to wrap a
length of material such as chart paper around the
pipe, aligning the edges of the paper precisely at
the overlap. With the edge of the chart paper
being parallel, then either edge describes a
circumference around the pipe that is
perpendicular to the pipe axis.
BISECTING THE CIRCUMFERENCE
Mark the chart paper exactly where it overlaps.
Then after removing the paper from the pipe, fold
the measured length in half keeping the edges
parallel. The fold line now marks a distance
exactly half way around the pipe. Put the paper
back on the pipe and use the fold line to mark the
opposite side of the pipe.
Transducer Cables
The transducers are connected to the electronics
via 50ohm coaxial cables and TNC connectors.
The total length of the cable be up to a maximum
of 200 mteres.
Keypad
All data is entered for set up and calibration via
the front panel keypad. Figure 9 shows the

Setup sensors
This gives the user the opportunity to change the
mode of operation from Reflex to Diagonal (see
figure 5, page 5).
When application information is programmed into
the instrument it automatically selects the mode of
operation from that data. It is possible however to
use the same sensors in different modes.
The Setup sensors option is available for two
main reasons. Firstly, if from the data that has
been entered the instruction comes back that the
sensors should be mounted in Diagonal mode, it
may be that this is not possible in the case of a
partially buried pipe. Under these circumstances,
provided that the velocity is low enough it may be
possible to use the transducers provided in Reflex
mode (see figure 4, page 5).
The second reason for this option is that in the
case of applications where the signal strength is
not strong enough to get through a corroded pipe
in Reflex mode, the instrument may be used in
Diagonal mode. This has the effect of increasing
the signal strength and maximum flow velocity.
The display will read the following.

although this option allows the user to adjust it if
necessary to match a specific requirement. The
DAC value is a number between 0 and 40,000,
which is a number internal to the Ultraflo.
The first stage is to adjust the output current to
