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

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.

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.

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.

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.
