PRINCIPLE of OPERATION
The Range Master ultrasonic level
measurement system operates by
transmitting an ultrasonic signal from the
transducer towards the product being
monitored. The reflected signal or echo is
received by the transducer and processed by
the amplifier. The time between transmission
of the ultrasonic signal and reception of the
echo is measured, and using the speed of
sound through air, the distance from the
transducer to the product being monitored
is calculated. The Hawk Range Master system
uses sophisticated software to locate and
track the correct echo without being affected
by echos from fixed objects or changes in the
product surface. When the product level or
surface conditions change, the system adopts
pre-selected signal tracking parameters. In
the event of a total loss of signal, the system
adopts pre selected signal recovery routines
to relocate the correct product level. The
system employs automatic gain control to
compensate for changes in echo amplitude,
due to changes in environmental conditions.
The system has continuous current, voltage
and relay outputs. These outputs can be
programmed for failsafe conditions in the
event of a loss of signal or system malfunction.
The factory settings are based on years of
experience in acoustically difficult
applications. This typically means that the
system can be installed and made operational
in a minimum of time.
DIGITISING
Digitising is a software routine that creates
an acoustic map of the vessel being
monitored. The map is used to store
information about the system transmit pulse
and the amplitude and location of all echoes
within the mapped distance. The Mapped
data is used during signal processing, and
provides a high level of discrimination to
remove the effects unwanted echoes.
Refer figures 1, 2, and 3. Unwanted echoes
can be caused by imperfections in the
transducer mounting and by features within
the vessel i.e. ladders, struts, support beams.
Digitising, along with transducer mounting
and location are crucial steps in setting up
your RangeMaster and if done correctly, will
enhance system performance.

BLANKING DISTANCE
The blanking distance is the minimum
distance from the face of the transducer that
the product being monitored can be reliably
detected. When the transducer is energized,
it vibrates causing an ultrasonic signal to be
emitted, and continues to vibrate for a short
time after the energy source is removed. The
time taken for the transducer to energize and
then stop vibrating is measured and
converted into a distance equivalent and is
called the blanking distance. Refer to Figure 4.
0
decreased automatically when the return
echo is above a defined amplitude. This means
that when the monitored product comes
closer to the transducer and the echo
amplitude increases, the system gain is
reduced. The reduced gain means the
blanking distance is reduced. Refer to
Figures 5 and 6.

The blanking distance is influenced by a
number of factors. The main factors are
transducer frequency and system gain. Lower
frequencies and higher system gains mean
longer blanking distances. The Transducer
frequency is application and range dependent.
Applications where long distances, dust,
steam, foam, or condensations are expected
should use lower frequency transducers. The
Range Master system utilizes adaptive gain.
Adaptive gain means that the system gain is

TEMPERATURE COMPENSATION
The velocity of sound through air is affected
by changes in the ambient temperature, and
changes by 0.17% per degree Celsius (0.10%
per degree Fahrenheit). Therefore, if there
were a 10°C (17°F) change in the application
there would be a 1.7% change in the velocity
of sound. Since ultrasonic level measurement
systems rely on the velocity sound to
calculate distance, there would also be a 1.7%
error in the distance measured. The Hawk
ultrasonic level measurement system is
designed to compensate for changes in the
ambient temperature within the vessel being
monitored. This is done by one of two
methods.
2. Utilizing a temperature sensor to measure
the ambient temperature of the
application.
There are two types of temperature sensor
available.
1. Internal: Within the transducer assembly.
2. External: Mounted separate from the
transducer assembly.
An external sensor is recommended where
the transducer temperature does not
accurately reflect the application temperature.
The external temperature sensor can be
installed in an appropriate position within
the vessel to monitor the application
temperature.
1. Nominating a fixed temperature within the
software setup which best represents the
average temperature of the application.
VAPOUR COMPENSATION
The velocity of sound will vary depending on
the medium it is travelling in. For example,
the Velocity of sound at 0°C (32°F) is in dry
air 331 m/s (1086 ft/s) and in CO2 is 259 m/s
(850 ft/s), a difference of 21.73%. This can
introduce significant errors in the measured
Refer table 3, page 6.
distance when using ultrasonic measuring
systems. The Hawk Range Master has the
flexibility to adjust the velocity of sound used
in calculations, and therefore compensate for
a wide variety of environmental conditions
within the vessel being monitored.
TRANSDUCER FREQUENCY SELECTION
The transducer frequency should be selected
to best match the application. Generally, lower
frequencies should be used for long distances
and higher frequencies for short distances.
The frequency selection must also take into
account the application in which the
transducer is to be mounted. In high dust,
steam, foam, or condensation applications,
lower frequencies will work with greater
efficiency and reliability. The following' s will
give some guidelines.

the optimum frequency for your application.

INSTALLATION GUIDE
AMPLIFIER
TRANSDUCER
Select a suitable mounting position that is
not in direct sunlight. If necessary, utilize a
sunshade. Refer figure 13, page 10. Observe
the minimum and maximum temperature
limits (-20°C/-4°F to 60°C/140°F) Do not mount
near sources of high E.M.F. such as high
current cables, motor starters, or S.C.R.
variable speed drives. Avoid mounting in high
vibration areas such as handrails and rotating
plant. Use rubber absorption mounts if
mounting in light vibration areas. Remove
the P.C.B. assembly before drilling cable and
conduit entry holes.
Selecting a suitable position to mount the
transducer on the vessel is the single MOST
IMPORTANT step. Please read all of the
installation guide and contact your Hawk
representative if you have any doubts or
questions. The mounting position must allow
for the blanking distance. That is, the
transducer face MUST be at least the blanking
distance away from highest the product level
in the bin, tank, or silo at all times. Refer to
table 4 below.

Where possible use the conservative values
and increase this distance by 50% if there is
foam, dust, steam, or condensation in the
vessel being monitored. Refer "Blanking
Distance" page 3. If using a flange mounting,
use a rubber or neoprene gasket and washers.
If using a nipple mounting, ensure that the
mounting bracket is >6mm (0.24 in) from the
rear of the transducer. Do not over tighten
the lock nuts. When using a focaliser cone,
ensure that it protrudes at least 50mm (2 in)
into the vessel. If the transducer needs to be
mounted above the roofline, use an
appropriate standpipe or nozzle. Refer figures
7 page 8 and figure 16 page 12. Use common
sense when selecting the mounting position.
A clear line of sight from the transducer to
the product being monitored is preferred.
Monitoring Solids
In general, the transducer mounting position
can be determined by measuring the distance
from the infeed to the vessel wall, and
mounting the transducer l/3r this distance
from the wall. Refer figures 7 and 8, page 8.

Avoid mounting near ladders, baffles, agitators
etc. Refer to figures 9, 10 and 11, page 9.
The external temperature sensor is used
where the application temperature is
significantly different to the temperature at
the face of the transducer. The external
temperature sensor should be mounted in a
position which will best represent the
application temperature to ensure accurate
temperature compensation.

Is the product height at the required scaling

If yes, go to I, If no, go to II.
27
SCALING YOUR VESSEL cont'd
I. Use the formula:
Cone radius = total height x h% x r
cone height
1
Percentage of volume = total height x h% x 1/3πcr2 x 100
total volume
1
Refer example 1 below.
Where h% is the percentage of total height and cr is the cone radius at the scaling point being
calculated.
II. Use the formula:
Percentage of volume = (total height x h% - cone height) x πr2 + cone volume x 100
total volume
1
Refer
example 2
page 29.
Where h is the percentage height at the scaling point being calculated.
Note: You need to calculate the Percentage volume for each scaling point.
Calculation examples using data from figure 24 and table 12 on page 29.
Example 1. Product height LOWER than or EQUAL to cone height:
Calculate the following:
Cone Radius = total height x h% x r
cone height
1
Percentage of volume = total height x h% x 1/3πcr2 x 100
total volume
1
Where h% is the percentage of total height and cr is the cone radius at the scaling point being
calculated.
Cone Radius = 12m x 25% x 3m = 2m
4.5m
1
Percentage Volume = 12m x 25% x 1/3π2m2 x 100 = 4.94%
1
254.6m3
Therefore scaling point 6 would be entered
6: 25.0 > 4.9
28
Therefore, at 25% of vessel
height the scaling point is
4.94% of total volume.
Example 2.
Product height HIGHER than cone height:
Calculate the following:
Percentage of volume = (total height x h% - cone height) x πr2 + cone volume x 100
total volume
1
Where h is the percentage height at the scaling point being calculated.
Therefore, at
55% of vessel
height the
scaling point is
40.0% of total
volume.
Percentage of Volume = {(12m x 55% - 4.5m) x πr2} + 42.4m3 x 100 = 39.97%
1
254.6m3
Therefore scaling point 12 would be entered
12: 55.0 > 40.0
Entering your Scaling Points
You now need to enter the calculated scaling points.
The display should now show 1: 0.0 > 0.0

Go to step 16, page 21.
This table is based on 5% head increments. For
better accuracy the increments can be smaller
at the higher head values.
The 0% and 100% head should correspond
respectively to the low level and high level. This
is not essential, however the % values will
become more complicated and the 4 to 20mA
output will have to be reconfigured if it is
required to indicate flow.
The flume specifications are required to obtain
the exponent, and the 100% full scale value.

S06 FILL RATE
Defines the fill rate in the chosen units per
hour, and should be set to approximately
120% of the expected maximum fill rate of the
vessel being monitored. For applications with
very fast fill rates (> 60m/h, 200ft/hr), EXPRESS
should be chosen. To select EXPRESS, press
and hold the button until EXPRESS is
displayed.
Table 15.
* ONLY available on dual channel amplifiers.
† Refer D Span below.
RESOLUTION
This sets the resolution of displayed distances
for both programming and level indication.
S06 EMPTY RATE
Defines the empty rate in the chosen units
per hour, and should be set to approximately
120% of the expected maximum empty rate
of the vessel being monitored. For
applications with very fast empty rates (>
60m/h, 200ft/hr), EXPRESS should be chosen.
To select EXPRESS, press and hold the
button until EXPRESS is displayed.
D SPAN
If DIFF SP (differential space) or DIFF MAT
(differential material) is selected as the output
mode for channel 1, D SPAN (differential span)
sets the span for the 4 - 20mA output for
channel 1 and operates according to the
DIFFERENCE in the measured distance of
Channel 1 and Channel 2. E.g.: If the D SPAN
is set to 1.00m, the analog output would be
4mA when the difference betweenCH1 and
CH2 is 0m, and would be 20mA when the
difference between CH1 and CH2 is equal to
or greater than 1.00m.
Note: the distance from the face of transducer
1 to the product must be less than or equal to
the distance from the face of transducer 2 to
the product for correct operation.
RST TRACKING
Automatically sets some parameters to
software defined values dependant on the fill
and empty rates. If the APPLICATION is
changed or the FILL/EMPTY rates are
significantly modified, you will be prompted
to reset tracking.
Options: YES or NO
S07 BLANKING
Defines the distance from the transducer face
where no echo can be detected.
S03 LOW LEVEL
Defines the bottom of the measurable span,

SETUP ~ Description cont'd
S08 DAMPING
Defines the rate of change of the displayed
information AND the analog outputs during
filling and emptying of the vessel. A lower
number will give a faster response and a
higher number will give a slower response.
There are two numbers displayed on the LCD,
the first number is the damping value for
filling, and the second number is the damping
value for emptying.
S09 RELAYS
There are programmable relays in the Range
Master. Each of them can be independently
programmed switch on and off at user
selectable set points.
If you have a dual channel Range Master, you
first need to assign the relay function. The
functions are XDUCER1, XDUCER2, DIFF, and
AVERAGE.
DEN TEMP: Relay is NORMALLY DE
ENERGIZED and will energize
when the monitored
temperature rises above T1 and
de energize when the
temperature falls below T1.
EN GAIN: Relay is NORMALLY ENERGIZED
and will de energize when the
system gain rises above G1 and
re energize when the system gain
falls below G1.
DEN GAIN: Relay is NORMALLY DE
when the system gain rises
above G1 and de energize when
the system gain falls below G1.
RELAY CYCLING/ALTERNATE
Set Alternate to "ON" to enable relay cycling.
Relay cycling allows the user to program relay
1 and relay 2 to alternate their set points
sequentially. This means that during the first
fill/empty cycle relay 1 and 2 will switch at
their programmed set points. During the
second fill/empty cycle relay 1 will switch at
the set points for relay 2, and relay 2 will
switch at the set points for relay 1. At each
subsequent fill/empty cycle, the set points
for relays 1 and 2 will alternate. This is
typically used for pump cycling operations.
XDUCER 1 or 2
Assigns the relay to a transducer. Relays will
switch depending on the measured level from
the assigned transducer.
DIFF
Relays will switch depending on the
differential of channel 1 and channel 2.
AVERAGE
Relays will switch depending on the average
of channel 1 and channel 2.
The operating modes for the relays are OFF,
EN LEV, DEN LEV, EN TEMP, DEN TEMP, EN
GAIN, and DEN GAIN.
OFF:
Relay is de energized at all times.
EN LEV:
Relay is NORMALLY ENERGIZED
product level in the vessel rises
above L1 and re energize when
the level falls below L2. L2 must
be ≥ to L1. Distances L1 and L2
are distances from the face of
the transducer.
DEN LEV:
EN TEMP:
S10 LOW OUTPUT
Defines the analog output that corresponds
to the LOW LEVEL. The default is 4mA and
can be adjusted between 0 and 20mA.
S11 HIGH OUTPUT
Defines the analog output that corresponds
to the HIGH LEVEL. The default is 20mA and
can be adjusted between 0 and 20mA.
S12 SIMULATE
Simulate allows the user to test the analog
output and relay set points by simulating
changes in the measured distance. The display
will show the simulated distance from the
transducer on the left-hand side, and the
corresponding product quantity on the righthand side. The analog output will change
proportionally and the relays will energize
and de energize at their respective set points.
Relay is NORMALLY DE
when the product level in the
vessel rises above L1 and de
energize when the product falls
below L2. L2 must be ≥ to L1.
Distances L1 and L2 are
distances from the face of the
transducer.
S13 TEMPERATURE
The Range Master can be setup to compensate
for changes in the temperature within the
vessel. The temperature source (S12M) is
selectable. The options are FIXED °C, FIXED
°F, SENSED °C, and SENSED °F. The ambient
Relay is NORMALLY ENERGIZED
monitored temperature rises
above T1 and re energize when
the temperature falls below T1.
33
SETUP ~ Description cont'd
temperature (S12A) is adjustable. If FIXED is
selected, S12A should be set to the normal
operating temperature within the vessel, and
if SENSED is selected, S12A should be set to
the actual temperature within the vessel at
time of selection.
FIXED
Assumes that the selected
temperature is the ambient
temperature at all times, and the
measured distance is not
compensated for changes in
temperature.
SENSED
The Range Master measures the
temperature and compensates
the measured distances for
changes in temperature. The
selected temperature is assumed
to be the ambient temperature
at the time of selection and is
used as a 1-point calibration.
S14 FAILSAFE
Assigns default analog output in case of a loss
of echo or system fault, and a time delay
before entering FAILSAFE condition. The
analog output (S13M) is selectable, and the
time delay (S13T) is adjustable from 0:00:10
to 7:59:59.
The options are:
LAST KNOWN The last know analog value
before entering failsafe
condition.
MIN LEVEL
The analog output will ramp
down to 4mA.
MAX LEVEL
up to 20mA.
<MIN LEVEL
down to BELOW 4mA.
>MAX LEVEL
up to ABOVE 20mA .
S15 CAL CODE
Changes the default code for entry to setup
from 0 to any number between 0 and 999.
This allows the user to restrict access to the
setup parameters of the Range Master. If
changed, the assigned number MUST be
entered to gain access to all setup parameters.
IF you change the CAL CODE, make sure you
record it.

TROUBLESHOOTING
False High Level Indication:
If the RangeMaster displays a false high level,
particularly at a low liquid level the most
likely cause is excessive transducer ring
down.
Transducer Ring Down Explained:
After the RangeMaster sends a pulse to the
transducer, there is a definite period of time
before the transducer stops vibrating. This
is termed transducer ring down. When the
RangeMaster is turned on for the first time,
the transducer is pulsed several times, and
the ring down characteristics are stored in
memory. This stored information is used
during normal operation to reduce the effect
of ring down on valid echo detection.
RING DOWN
ECHO
Figure 27.
The trace diagrams show typical traces
measured using the test pins on the
RangeMaster circuit board . As can be seen,
the ring down is significantly different for
each trace. The large ring down shown in
Figure 27 above, could be interpreted as a
potential valid echo and cause a false high
level to be detected. This is because the gain
of the RangeMaster is raised at low levels to
detect the lower amplitude echo from the
product surface. (Echo amplitude is generally
inversely proportional to the distance from
the transducer), causing the ring down to
appear large.
RING DOWN
ECHO
Resolution:
1. Perform a "DIGITISING" procedure to
measure and save a new transducer profile.
Refer Digitising pages 2 and 20.
"DIGITISING" is designed to remove the
effects of excessive ring down as shown
in Figure 27 above.
2. Check that there is no build-up of product
on cone.
3. Check that cone is not missing or damaged.
4. Check that transducer is installed correctly.
Refer Pages 7 to 9.

The top trace is the 'window' trace. The
'window' indicates the position the
RangeMaster considers the correct echo, and
therefore level to be. For an echo to be
considered it must larger than a software
defined threshold. If an echo is greater than
the threshold a register is placed on the
'window' trace.
