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 m eas ure 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

3

/hr, m3/min, m3/sec, g/min, USg/hr, l/m in, l/sec

m
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 brack ets provided (see Figure
2 for m ounting pattern) . Drilling f urther f ixing holes
in the Housing rem ove the IP67 protection rating
and CE approval.

Mounting the housing into position does not
require the rem oval 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 f or mounting the
electronics, connecting all cables and checking

the power supply, the power can now be applied.
The Ultraflo 2000 is now ready for program ming.
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 pr ovided 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 c onnected 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.

ULTRAFLO 2000 INSTALLATION & OPERATING INSTRUCTIONS

Transducer Hardware

Transducer alignment guide rails, chains and
couplant are supplied with all units in order to
ensure that the transducers are accur ately aligned
with respect to the pipe axis.

A single guide rail assembly is supplied for
mounting the transduc ers in Reflex m ode and two
guide rails are provided for m ounting 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 determ ines the correct har dware to be
supplied with each instrument.

Reflex Mode

Reflex mode is a def ault setting on all applic ations
up to 215mm. Above this the instrument will
default to Diagonal mode. It is possible to change
these default settings if required (s ee page 11 Set
up sensors).

Before attempting to attach the transducers it is
imperative to ensure that the cor rect position has
been chosen to site the trans ducers 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 instr ument 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 separ ation distance and
repeat the procedure. The separation
distance is measured f rom 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 m oving the transducers into position
ensure that they are withdrawn into the guide rail
as far as possible. T his ensures that the couplant
will not be removed from the transducer face
before it is screwed down into position.

ULTRAFLO 2000 INSTALLATION & OPERATING INSTRUCTIONS

(D)

All transducers are m ounted 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 ar e mounted on opposite sides
of the pipe as shown in f igure 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 poss ible to repr ogr am 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.

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 mater ial 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 rem oving 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 c onnected to the electronics

via 50ohm coaxial cables and TNC connectors.
The total length of the cable be up to a m axim um
of 200 mteres.

Press ENTER to select this option.

MAIN MENU

Setup sensors

This gives the user the opportunity to change the
mode of operation from Reflex to Diagonal (see
figure 5, page 5).

When applic ation information is programmed into
the instrument it autom atically selects the mode of
operation from that data. It is poss ible 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 transduc ers 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 cor roded pipe
in Reflex mode, the instrument may be used in
Diagonal mode. T his has the effect of increasing
the signal strength and maximum flow velocity.

The display will read the following.

APPLICATION NOTES

The ULTRAFLO 2000 is a “Transit Time”
Ultrasonic flowmeter which has been designed to
work with “Clamp On” transducer s, thus enabling
liquid flowing within a closed pipe to be measured
accurately without the need for any mechanical
parts to be inserted either through the pipe wall or
protrude into the flow system.

The meter is controlled by a micro-processor
containing a wide range of data which enables the
instrument to measure flow in any pipe diameter
from 13mm bore up to 5000mm, made of any
material and over a wide range of operating
temperatures.

The system operates as follows:

When ultrasound is transmitted from transducer
“X” to transducer “Y” the speed at which the sound
travels through the liquid is accelerated slightly by
the velocity of the liquid. If sound is transm itted in
the opposite direction from “Y” to “X” it is
decelerated because it is travelling against the
flow of the liquid. The differ ence in time taken to
travel the same distance but in opposite directions
is directly proportional to the flow velocity of the
liquid.

Having measured the flow velocity and knowing
the pipe cross-sectional area, the volum etric flow
can be easily calculated. All of the calculations
required to first determine the c orrect siting of the
transducers and subsequently compute the actual
flow are carried out by the microprocessor.

To measure flow, it is first necessary to obtain
detailed information about eac h application, which
is then programmed into the processor via the
keypad. This information must be accurate
otherwise flow measurement errors will occur.

Further having calculated the precise position at
which the transducers m ust be clamped onto the
pipe wall, it is equally important to align and
separate the transducers accurately with respect
to one another, as failing to do so will again cause
errors in measurement.

“X”

FLOW

“Y”

Finally to ensure accurate flow measurem ent it is
imperative that the liquid is flowing uniformly within
the pipe and that the flow profile has not been
distorted by any upstream or downstream
obstructions.

To obtain the best r esults from the Ultraflo 2000 it
is absolutely necessary that the following rules for
positioning the transducers are adhered to and
that the condition of the liquid and the pipe wall
are suitable to allow transmission of the sound
along its predetermined path.

Selecting A Meter Position

As the transducers with the Ultraflo 2000 are
clamped to the outside surface of the pipe, the
meter has no way of determining exactly what is
happening to the liquid. The assum ption therefore
has to be m ade that the liquid is flowing uniform ly
along the pipe, either under fully turbulent
conditions or under laminar flow conditions.

It is further assumed that the flow velocity profile is
uniform f or 360° around the pipe ax is. T he Ultraf lo
2000 is normally supplied calibrated for use on
turbulent flows but by adjustment of the CAL
FACTOR the instrument can be used for lam inar
flow applications.

Figure 11

Figure 11 shows a unifor m prof ile as com par ed to
a distorted profile.

The difference between (a) and (b) is that the
“Mean Velocity” of the flow across the pipe is
different and the Ultraflo 2000 expects a uniform
flow as in (a). The distorted flow in (b) will give
measurement er rors which cannot be predicted or
compensated for.

Flow profile distortions result from upstream
disturbances such as bends, tees , valves, pumps
and other similar obstructions. To ensure a
uniform prof ile the transducers must be mounted
far enough away from any cause of distortion such
that it no longer has an effect.

The minimum length of upstream straight pipe is
20 diameters and 10 diameters downstream which
ensures that accurate results will be achieved.
Flow measurements can be made on shorter
lengths of straight pipe down to 10 diameters
upstream and 5 diameter s downstream, but when
the transducers are sited this close to any
obstruction errors can be considerable.

It is not possible to predict the amount of error as
this depends entirely upon the type of obstruction
and the configuration of the pipework. The
message therefore is clear. Do not expect to
obtain accurate results if the transducers are
positioned closer than allowed to any obstruction
that distorts the uniformity of the flow profile.

Examples of the effects of two different pipe
configurations are shown in Figure 13.

Figure

Mounting The Transducers

It will be impossible to achieve the accuracy of
measurement s pecified for the Ultraflo 2000 if the
transducers are not clam ped to the pipe correctly
and if the data - I.D., O.D., Temperature, Pipe
Material are not accurate.

The transducers are supplied with a guide rail, the
purpose of which is to ensure that the transducers
are aligned accurately with the pipe axis and that
the face of the sensor is tangential to the axis.

Apart from the correct positioning and alignment
of the transducers, of equal importance is the
condition of the pipe surface in the area under
each of the transducers.

An uneven surface that prevents the transducers
from sitting flat on the surface of the pipe can
cause Signal Level and Zero Offs et pr oblems. The
following procedure is offered as a guide to good
practice with respect to positioning and mounting
the transducers.

1. Select the site following the rules laid down on
page 17.

2. Inspect the surf ace of the pipe to ensure it is
free from rust and unevenness. Transducers
can be mounted directly on painted surfaces
as long as the surface is smooth and that the
underlying metal surface is free from rust
particles. On bitumen or rubber coated pipes
the coating must be removed in the area
under the transducers as it is pref erable that
the transducers are mounted directly on to
base metal.

3.

Transducers can be m ounted on both Vertical

Horizontal pipe runs.

4. Apply interface couplant to the face of the
transducers.

The amount of couplant used is extremely
important particularly on pipes of less than 100mm
bore. Use the syringe supplied with the instrument
and apply couplant as shown.
On small pipes below 90mm the bead of grease
used must be approxim ately 20mm long and 2mm
maximum diam eter. Using m ore greas e will cause

18

ULTRAFLO 2000 INSTALLATION & OPERATING INSTRUCTIONS

(

wall signals to be generated which cause err ors in
measurement.

Figure 15

On Stainless Steel pipes the amount of couplant
applied should never exceed the amount indicated
in the examples above. For large plastic and steel
pipes the amount of couplant applied is less
critical however do not use more than is absolutely
necessary.

5. Attach the guide rail assembly to the pipe so
that it is perfectly parallel to the pipe axis.

6. When sc rewing the transducer s on to the pipe
surface use only enough force to ensure that
the transducer is flat against the pipe sur face
and then lock in position.

7. Clamping the transducers in exactly the
correct position is extremely important. The
Ultraflo 2000 calculates the separation
distance and the transducers must be
positioned and clamped exactly at the
distance specified.

8. Always use the couplant provided.

Liquid Conditions

Transit Time ultrasonic meters perform best on
liquids that are totally free from entr ained air and
solids. With sufficient air in the system the
Ultrasound beam can be attenuated totally and
therefore prevent the instrument from working.
Often it is possible to tell whether there is air in the
system or not.

If a flow signal cannot be obtained a simple test to
determine whether the flow is aerated involves
cutting off the flow for a per iod of 10 - 15 m inutes.
During this time the air bubbles will rise to the top
of the pipe and the flow signal should return.

When the flow signal has retur ned “Switch on” the
flow and if sufficient entrained air is locked in the
system it will very quickly disperse and kill the
signal.

Propagation Velocity

To make a flow measurement using the Ultraflo
2000 on any liquid other than water it is necessary
to know the propagation velocity in

metres/second, of the particular liquid. Micronics
can supply this information.

Maximum Flow

The Ultraflo 2000 is normally supplied with
hardware suitable for the specific application for
which the instrument has been purchased. It is
possible to use the instrument on a wide range of
applications as long as the transducers will cope
with the maximum velocity and temperature
required.

Application Temperature

On any application with an operating temperature
above or below ambient tem perature, ensure that
the transducers reach and are maintained at the
application temperature before undertaking
calibration.

When applying the transducers to low temperature
pipes, do not allow the pipe surface to ice up
between the transducer and the pipe wall.

Wherever possible insulate the transducers such
that variations in ambient air temperature do not
effect the relationship between the trans ducer and
the liquid temperature.

The instrument automatically compensates for
changes in application temperature over a range
of approximately +/- 20°C.

ULTRAFLO 2000 INSTALLATION & OPERATING INSTRUCTIONS

1. Installation

Connect the flow transducers to the instrument as described in the HARDWARE section of this
manual. Note that the Ultraflo must read positive flow otherwise the energy displayed will read zero.

Attach the temperature probes to the outside of the flow and return pipes. Use the stainless steel
banding to attach the temperature probe. Heat sink compound should be applied between the probe
and pipe for better heat transfer. Lagging should then be wrapped over the temperature probe itself
to stabilise the temperature.

One temperature probe should be attached to the feed pipe as the HOT SENSOR and the other is
attached to the return pipe as the COLD SENSOR.

Figure 17

Remove the terminal lid and connect the temperature probes’ making sure the power is turned off.
Connect the HOT sensor to the terminal marked HOT (Pins 5,6,7) and the COLD sensor to the
terminal marked COLD (Pins 8,9,10). A reversed temperature connection will make the

measured energy zero.

MA1 MA2 HOT COLD RELAY 24VDC AC IN
IN

The WHITE core from each temperature probe must always be connected to the negative (Pins 6
and 9). The other two cores on each temperature probe connect to either of the positive terminals
(Pins 5, 7and Pins 8,10). Always remember to earth the PT100 probes using the screen core.

The PT100 are subject to interference from power sources such as, pumps and invertors and
any electrical equipment. The interference will cause an error in the measurement of
temperature.

2. Operation

Connect power to the instrument and wait for a few seconds.

1. Follow the Quick Start menu on page 8 to read flow. Note that if the fluid selected is not water,
the user will be prompted for the SHC (specific heat capacity) and the density relative to water
(specific gravity). For water @ 20°C the SHC is 4.2 kj/m
calculate the SHC figure to enter into the unit find the SHC of the liquid being measured in kJ/kg
K and divide by 4.2 kJ/kg K. Now enter this figure into the unit.

2. To calculate the relative density, find the density in kg/m
20°C (996 kg/m
available from your supplier.

3. Select the Energy units required when setting up the display or outputs from the FUNCTION
menu on page 13. Scroll through the options and press ENTER to select.

4. It is now possible to set either of the two 4-20mA outputs for Flow/Energy or Temperature
differential as described in FUNCTIONS on page 13.
