Sonar Principals of OperationThe Hawk "SA" Sonar Level Transmitter emits a sound pulse towards the interface blanket (bed level,
settling solids etc) which is at the bottom of the tank (sedimentation tank, primary clarifier, secondary
clarifier, humus tank, thickener DAF tank, tailings dam etc).
The pulse signal is reflected off the interface, back to the sonar transducer. The sonar transducer
interprets the signal, compensates for temperate and provides a distance reading and output,
proportional to the distance between the sonar transducer and interface level. The display can read
from the sonar transducer down to the interface, or from the bottom of the tank to the top of the
interface.
Selcting a Sonar Transducer Frequency
Performance of a Sonar interface transmitter is very dependent on the choice of the sonar transducer
operating frequency.
Example (1) Water Treatment Plant(measuring floculent blanket)
Floc is very light in density and can vary for different water types and the sources of the water.
To detect the actual interface, we must use a high frequency (short wavelength) sonar transducer to
detect the small impedance difference between the water and floc interfaces. This frequency range
could typically be between 300kHz and 700kHz. Floculant is added to encourage settling of solids
particles
Note:A lower frequency sonar transducer may not see the floc interface at all and measure the tankbottom only.
Example (2) Mining Process Thickener(measuring bed level)
There could be two interface levels that are of interest to metalurgists or process engineers, in a mining
thickener application.
Bed Level
The bed level density is generally high in comparison to other interfaces in the thickener tank.
To measure the "bed" only and not be affected by the lighter floc level or particles in suspension, we
must use a lower frequency sonar transducer to "diffract" around the particles and "See through" thelighter densities in suspension. These sonar frequencies can range from 70kHz down depending on the
size and density
To measure the "floc layer" interface that sits above the bed level which is lighter in density, we
use a higher frequency sonar transducer than for the bed level. These sonar frequencies range from
150kHz to 30 kHz.
By selecting the appropriate sonar frequency, we optimize the amplitude of the return signal from
the chosen interface to minimize commissioning time.

The advantages in using sonar interface transmitters on thickener tanks are:
(1) By controlling the underflow pump rate, the density of the bed can be optimised for
downstream process requirements.
(2) The sonar transmitter can measure to the bottom of the tank and is not affected by
the scraper passing underneath. Other interface technologies eg. displacement float,
electrical mechanical dipping infra-red can only measure above the scraper.
(3) When the sonar transmitter is used in conjunction with an underflow density gauge
there can be a determination if the tank is being over flocced, which can result in a lower
bed density.
(a) The underflow density gauge reads a lower density. The sonar interfacemonitors a bed level that is at an "acceptable level".
Possible cause: over floccing the tank.
(b) The underflow density gauge reads a lower density, the scraper torque
amperes are high, the sonar interface monitors a bed level that is low, reduce the underflow
pump rate and build the bed higher.
Cause: overpumping rate on the underflow pump.
(4) When the sonar interface transmitter is used it can provide feedback to the "Floc
dosing control loop" when there is an increase in suspended solids between the sonarsensor and bed level.
This could be attributed to,
(a) Stratified layers at varying densities appearing at different levels.
(b) Pinfloccing in suspension or other particles in suspension not settling.
Both problems require further consideration to floc dosing control, where (a) could be
improved perhaps with an increase floc dose rate, (b) pinfloc in suspension could indicate
a problem with the bed and other suspended solids in suspension at a high level could
require higher floc dosing.
(5) Using scraper torque amperes for controlling underflow pump rates can be a major
problem.
(a) Scraper amperes are affected by density changes and do not relate only to
bed level
(b) Mechanical wear and tear will affect scraper amperes
(c) Thickener infeed rate will affect scraper amperes.

Sewage Treament Plants: Sludge Interface Applications
(A) Primary sedimentation tank
Primary Clarifier
The main application of the sonar interface transmitter for these tanks is to,
(1) Maintain a bed level in the tank by controlling the settled solids sludge pump.
The advantages are:
(A) To optimise the density of the sludge being pumped to the thickener or to the
DAF tanks (dissolved air floatation tanks).
(B) To reduce wear of the sludge pump.(C) To reduce running costs eg electricity, maintenance etc.
(D) Reduce the run time of filter presses.
(E) Provide alarm status on tanks on continous barsts.
(B) Secondary Clarifier / Final clarification
The main applications for the sonar interface transmitter for these tanks are
(1) Maintain a bed level in the tank, by controlling the RAS pump (return activatedsludge.
(2) Provide alarms or monitor fluff/pinfloc levels rising in the tank. (Fluff/Pinfloc is
caused by an out of balance biological affect and results in an increase of suspended
solids in the clarifier)
The advantages are:
(A) To optimise the density of the sludge being pumped back to the aeration tanks
(RAS) and to optimise the sludge being pumped to the thickener, "DAF" tanks (wasteactivated sludge
(B) To reduce wear of the sludge pump.
(C) To reduce "loading" of the aeration and thickener "DAF" tank areas.
(D) To reduce electricity and running costs.
(E) To reduce manpower requirements by autmation.
(F) To provide alarms over a GSM/page system, especially at unmanned treatment
plants, if the clarifier becomes unsettled and high levels of solids flow into the clarifier
launder.

Application Note Controlling Sludge level in PrimarySedimentation Tanks
Instrument: Hawk SAR-D-BS Transmitter ST002 sonar transducer
Client: Melbourne WaterSite: Eastern Treatment PlantApplication Primary sedimentation-Sludge interface control
Eastern treatment plant, is one of Australias largest sewerage treatment plants processing over450ML perday. There are 8 primary clarifers, all of which run 24 hours a day. Melbourne Waterrequired automaticcontrol of the primary sludge pump catering for peak and off peak loads, tooptimize the density of the sludgepumped to the DAF tanks. As well as reducing the load imposedon the sludge scraper blades to reduce wearand maintenance downtime. To do this they requireaccurate measurement of the interface blanket with asonar interface transmitter that had anautomatic cleaning mechanism. The interface transmitter neededto operate without operatorassistance, especially after hours.The system had many advantages over timedrelated solutions. Melbourne Water uses this systemin a controlled loop configuration, rather than just monitoringpurposes
The unit is mounted to the side
of the clarifier.The transducer
is mounted just under the
surface of the water. The
transmitter is locatedin the control
cabinet aprox 10 metres away.
The actuator strokes the transducer
in and out ofthe water with a
definite action causing any
buildup to be removed. This unit has
been in thesewerage for over 2
years without requiringmanualcleaning.
The profile of the tank shows a very defined interface. This
means that there is excellent settling of the solids with minimal
light interface. You can see from the above screen save that the
echo off the interface is over 2.5 volts. Melbourne Water have
used the analogue signal from this instrument to control the
speed of the pump which sends the sludge to the DAF area. Our
unit can monitor the level so they can ensure that they optomise
the sludge density while at the same time not let the level get tohigh which will put more wear on the mechanical scrapers

FUNCTION
The portable (PIA) weatherproof analyzer, allows for an early
determination of where the interface is. When the interface is
detected, an audible signal, as well as either a Bar Graph indicating
percentage or a 0 - 100% digital display, provides the operator
with all the necessary information to accurately gauge the interface
depth.
Because the analyzer uses sonar technology, it is not affected
by colour change, (eg. use of ferric chloride). A single sensor
works on all density levels, including applications with heavy
solids, such as the Daf area in a sewage treatment plant.
TYPICAL APPLICATIONS
s WASTE WATER TREATMENT PLANT: Primary andSecondary Clarifier Interface or bed level. Daf Plant.
s MINING: Clarifiers, thickeners, settlers, settling ponds.
s FOOD: Carbon columns.
s WATER: Clarifiers, potable and raw water plants.
KEY FEATURES
s Single sonar transducer, handles all density ranges.
s Rugged stainless (316SS) sonar transducer plus
metal carrying case and battery charger.s Audible alarm when interface detected, as well as digital
display.
s Not affected by colour change.

Principal of Operation
The PIA Series Sonar Interface/Density Analyzer
consists of a Hand Calibrater and the appropriateSSA-1-2-10 sonar transducer.
The transducer may be used on a wide range of
densities. The Interface/Density Analyzer, detects
a density change and provides an autible alarm as
well as a Bar Graph Display.
Example:
High density sludge with suspended solids can use
the same sensor as used for lower density
sludge/interfaces.
The PIA Sonar Interface/Density Analyzer transmits
a sound pulse towards the reflector plate. The pulse
signal is reflected off the plate, back to the sonar
transducer, then the PIA Analyzer interprets the
signal, compensates for temperature and provides,
an audible output and display of the sludge/interface.
Echo processing software monitors the operating
efficiency of the sonar transducer. When the density
of the monitored liquid increases or decreases thischange is displayed on the PIA Hand Calibrator in
% terms or simple bar graph representation. The
auto zero can be set in clean water or an area in
the tank where a lower density is known to be. This
will become the zero point and will show a
corresponding change on the Display (0%) of the
Hand Analyzer.
Using the Portable Interface Analyzer
As the PIA can be used in very light densities eg:
(water clarifier, measuring floculent) to heavy
densities (thickeners), an auto-calibrate is required
to set the zero (0%). The transducer (SSA-1) is
immersed below the surface of the liquid. A simple
push button function, will auto calibrate the
instrument to zero. Lowering the transducer into
the vessel, will see the display change in percentage,
as the density changes. An audible alarm, can be
set for a desired density level. Changing liquid
colours has no effect on the interface reading.
Features
s Full range of Echo processing software to cover
the heavy and light density interfaces.
s Audjble buzzer for blanket level detection,programmable to operate at a required density.
s NEMA 4X (IP67) enclosure for PIA Analyzer.
s NEMA 4X (IP68) enclosure for Sonar Transducer.
s Full operational diagnosics display on theoperation of the PIA Analyzer.
s Simple Auto Calibrate function.
s Re-chargable batteries, with battery charger.
s 4 hours continuous operation.
s One Sonar Sensor does all Densities.

PRINCIPAL OF OPERATION
The SA Series Sonar Level System consists of an SAtransmitter and the appropriate ST001, ST002, ST003,
ST004, ST005, ST006, ST007, ST008, ST009, ST010,
sonar transducer.
The transducer selection will vary dependent upon
the density of the interface to be detected. Performance
is very frequency (sonar transducer) dependent.
Example:
High density sludge with suspended solids
will use a lower frequency transmitter, to defract
the signal around the particles in suspension.
Lower density sludge/interfaces require higher
frequency transducers in order to maximize the return
signal.
The SA Sonar level transmitter emits a sound pulse
towards the interface/sludge which is at the bottom
of the clarifier/tank, etc. The pulse signal is reflected
off the interface, back to the sonar transducer, then
the level transmitter interprets the signal, compensates
for temperature and provides a distance reading, and
an analog output proportional to the sludge/interface
height. Modbus Communications is also available.
Echo processing software monitors the operating
efficiency of the sonar transducer. As the efficiency
of the transducer drops off due to build-up on the
sensing face (generally caused by fats settling out, or
suspended solids attaching to the transducer), the
sonar transmitter will increase the level of ultrasonic
cleaning of the face or where fitted will activate the
automatic Scum Cleaner which will remove all heavy
build-up on the sonar transducer.
As a rule, the lower the frequency, the greater the
pressure wave with each pulse, the greater the
cleaning.
Application Example:
Mining Thickener. (Dense mud layer)
For this application we must use a low
frequency sonar transducer to measure the
bed level and not see the floc interface level.
We select the ST009 (15kHz) sonar transducer
and appropriate housing material for chemical
compatibility. Also select the auto-scum
cleaner because of suspended solids that will
attach to the sensor, as well as minimizing
scale build-up. High temperature service to
150C (302F).
FEATURES
Full range of sonar transducers to optimisedetection of heavy and light density interfaces.
The SA Sonar transmitter handles all Hawksonar transducers.
Standard range to 15 metres. Option: 30 metres.
Ultrasonic cleaning (light build-up) of the sonartransducer face and automatic control of theheavy build-up Scum Cleaner (option).
4-20mA (Isolated) analog output for blanket/bedlevel or distance to blanket/bed (interface).
200m sonar transducer/sonar transmitterseparation distance.
NEMA 4X (IP67) enclosure for SA transmitter. 4 relays, field programmable for control purposes.
Modbus Communications, RS485.
Windows based Sonar Hawk diagnostic andcommunication software.
Full operational diagnostics display on the SAtransmitter.

Typically, the most difficult task when wanting to determine the level
of an interface, lies in the correct selection of the transducer frequency.
There are many other variables to consider. They include particle size,
flow, velocity, material, air bubble retention . . .
IN GENERAL, THE FOLLOWINGSHOULD BE UNDERTAKEN:
(1) Identify a position away from direct inflow, where turbulence is
minimised.
(2) If air bubbles are present within heavy suspended solids, use the
scum cleaner option.
(3) The transducer selection should be:

PRINCIPALE OF OPERATION
The SA Series Sonar Level System consists ofan SA transmitter and the appropriate ST001,ST002, ST003, ST004 or ST005 sonartransducer.
The transducer selection will vary dependentupon the density of the interface to bedetected.
Example:High density sludge with suspendedsolids will use a lower frequencytransmitter - ST001 or ST002.
Lower density sludge/interfaces require higherfrequency transducers in order to maximisethe return signal - ST003, ST004 or ST005.
Note:
See guideline selection chart for sonartransducers.
The SA Sonar level transmitter emits a soundpulse towards the interface/sludge which isat the bottom of the clarifier/tank, etc. Thepulse signal is reflected off the interface, backto the sonar transducer, then the leveltransmitter interprets the signal,compensates for temperature and providesa distance reading, and an analog outputproportional to the sludge/interface height.
Echo processing software monitors theoperating efficiency of the sonar transducer.As the efficiency of the transducer drops offdue to build-up on the sensing face (generallycaused by fats settling out, or suspended
solids attaching to the transducer), the sonartransmitter will increase the level ofultrasonic cleaning of the face or where fittedwill activate the automatic Scum Cleanerwhich will remove all heavy build-up on thesonar transducer.

PARAMETER and FLOW CHARTS
SetupTo gain access to the parameter menu, press
and hold the CAL button until "Unlock 0" is
displayed on the LCD. Then use the buttons
to select the access code. The factory default
is 0.
Units
Allows the user to select the units for display
of measured distances and relay set point
programming. The choices are metres or feet.
Display
Allows the user to select the prefered displayon the LCD, options Space, Material, % Material.
Application Type
Allows the user to select the type ofapplication Liquids, Slurries, Solids. Theresponse of the system is automaticallychanged to allow for application requirments.
Speed
Allows the user to select the approximatespeed of the level change. This automaticallysets various parameters to allow a faster or
slower response.Damping
Allows the user to define how quickly the switch
responds to changes in the measured level
within the vessel being monitored. A low
damping value gives a fast response and a high
damping gives a slow response. The damping
limits are from 0 to 239. Eg. If you set the
damping to a value of 60, the displayed distance
will be the average of the last 60 pulses.
Low Level - HA Series Only
Sets the distance from the face of the transducer
that corresponds to the low level in the vesselbeing monitored - 4mA analog output level.
High level - HA Series Only
Sets the distance from the face of the transducer
that corresponds to the High level in the vessel
being monitored - 20mA analog output level.
Note:When setting the High and Low levels aminimum span of 100mm MUST be maintained.
Blanking
Allows the user to blank out unwanted nearthe senor echoes. Any echoes within thisentered distance will be ignored.
Fail OptAllows the user to select their preferredFailsafe condition. There are 5 possible mAoutput failure values. They are: 20mA, 4mA,Last Known, 20.00mA.
Failsafe TimeAllows the user to enter the number of pulseswhen a last echo condition occurs prior tofailing. It is recommended to enter a minimumof 50 pulses.
RelaysAllows the user to set the relays for switching.The relays are programmed in a distance
from the transducer face to the position whereswitching is required.
Relays work in the following manner:
OFF The relays will remain de-energisedregardless of the measured distanceor vessel contents.
The relays can be programmed to energiseor de-energise depending on the product levelin the vessel being monitored.
FS If FS is selected, the relay will operateas a failsafe relay. The relay will beenergised at all times and willde-energise if the ultrasonic switchgoes in to failsafe condition.
EN The relay is normally energised andwill de -energise when the product risesabove the level determined by L1 andremain de -energised until the productfalls below the level determined by L2.
DEN The relay is normally de -energised andwill energise when the product risesabove the level determined by L1 andremain energised until the product fallsbelow the level determined by L2.
L1 L1 determines the first switch pointfor relay switching.
L2 L2 determines the second switch pointfor relay switching.
Note:L1 and L2 are set in the chosen displayunits relative to the face of the transducer.
BlankingAllows the user to set the blanking distancebeyond the minimum specified distance toignore unwanted echoes between the targetproduct and the transducer. Use thebuttons to set required blanking.
CodeAllows the user to set an access code otherthan 0 to avoid unauthorised changes to theprogramming. Use the buttons to select
the desired access code.
