PRINCIPLE of OPERATION


The Range Master ultrasonic levelmeasurement system operates bytransmitting an ultrasonic signal from thetransducer towards the product beingmonitored. The reflected signal or echo isreceived by the transducer and processed bythe amplifier. The time between transmissionof the ultrasonic signal and reception of theecho is measured, and using the speed ofsound through air, the distance from thetransducer to the product being monitoredis calculated. The Hawk Range Master systemuses sophisticated software to locate andtrack the correct echo without being affectedby echos from fixed objects or changes in theproduct surface. When the product level orsurface conditions change, the system adopts

pre-selected signal tracking parameters. Inthe event of a total loss of signal, the systemadopts pre selected signal recovery routinesto relocate the correct product level. Thesystem employs automatic gain control tocompensate for changes in echo amplitude,due to changes in environmental conditions.The system has continuous current, voltageand relay outputs. These outputs can beprogrammed for failsafe conditions in theevent of a loss of signal or system malfunction.The factory settings are based on years ofexperience in acoustically difficultapplications. This typically means that thesystem can be installed and made operationalin a minimum of time.

DIGITISINGDigitising is a software routine that createsan acoustic map of the vessel beingmonitored. The map is used to storeinformation about the system transmit pulseand the amplitude and location of all echoeswithin the mapped distance. The Mappeddata is used during signal processing, andprovides a high level of discrimination toremove the effects unwanted echoes.

Refer figures 1, 2, and 3. Unwanted echoescan be caused by imperfections in thetransducer mounting and by features withinthe vessel i.e. ladders, struts, support beams.Digitising, along with transducer mountingand location are crucial steps in setting upyour RangeMaster and if done correctly, willenhance system performance.

BLANKING DISTANCE

The blanking distance is the minimumdistance from the face of the transducer thatthe product being monitored can be reliablydetected. When the transducer is energized,it vibrates causing an ultrasonic signal to beemitted, and continues to vibrate for a shorttime after the energy source is removed. Thetime taken for the transducer to energize andthen stop vibrating is measured andconverted into a distance equivalent and iscalled the blanking distance. Refer to Figure 4.

Speed of Sound = 5.8mS/m (Inc. Echo return time)

Blanking Zone = 1.7mS ÷ 5.8 = 0.3m

Valid Echo = 5.8mS ÷ 5.8 = 1.0m

The blanking distance is influenced by anumber of factors. The main factors aretransducer frequency and system gain. Lowerfrequencies and higher system gains meanlonger blanking distances. The Transducerfrequency is application and range dependent.Applications where long distances, dust,steam, foam, or condensations are expectedshould use lower frequency transducers. TheRange Master system utilizes adaptive gain.Adaptive gain means that the system gain is

decreased automatically when the returnecho is above a defined amplitude. This meansthat when the monitored product comescloser to the transducer and the echoamplitude increases, the system gain isreduced. The reduced gain means theblanking distance is reduced. Refer to Figures 5 and 6.

TEMPERATURE COMPENSATION

The velocity of sound through air is affectedby changes in the ambient temperature, andchanges by 0.17% per degree Celsius (0.10%per degree Fahrenheit). Therefore, if therewere a 10°C (17°F) change in the applicationthere would be a 1.7% change in the velocityof sound. Since ultrasonic level measurementsystems rely on the velocity sound tocalculate distance, there would also be a 1.7%error in the distance measured. The Hawkultrasonic level measurement system isdesigned to compensate for changes in theambient temperature within the vessel beingmonitored. This is done by one of twomethods.

1. Nominating a fixed temperature within thesoftware setup which best represents theaverage temperature of the application.

2. Utilizing a temperature sensor to measurethe ambient temperature of the application.

There are two types of temperature sensoravailable.

1. Internal: Within the transducer assembly.2. External: Mounted separate from the

transducer assembly.

An external sensor is recommended wherethe transducer temperature does notaccurately reflect the application temperature.The external temperature sensor can beinstalled in an appropriate position withinthe vessel to monitor the applicationtemperature.

VAPOUR COMPENSATION

The transducer frequency should be selectedto best match the application. Generally, lowerfrequencies should be used for long distancesand higher frequencies for short distances.The frequency selection must also take intoaccount the application in which thetransducer is to be mounted. In high dust,steam, foam, or condensation applications,lower frequencies will work with greaterefficiency and reliability. The following' s willgive some guidelines.

The velocity of sound will vary depending onthe medium it is travelling in. For example,the Velocity of sound at 0°C (32°F) is in dryair 331 m/s (1086 ft/s) and in CO2 is 259 m/s(850 ft/s), a difference of 21.73%. This canintroduce significant errors in the measured

distance when using ultrasonic measuringsystems. The Hawk Range Master has theflexibility to adjust the velocity of sound usedin calculations, and therefore compensate fora wide variety of environmental conditionswithin the vessel being monitored.

TRANSDUCER FREQUENCY SELECTION

It is crucial to system performance to matchthe transducer frequency to the size andenvironmental conditions of the vessel beingmonitored. Always seek advice from yourHawk representative if you are unsure aboutthe optimum frequency for your application.

AMPLIFIERSelect a suitable mounting position that isnot in direct sunlight. If necessary, utilize asunshade. Refer figure 13, page 10. Observethe minimum and maximum temperaturelimits (-20°C/-4°F to 60°C/140°F) Do not mountnear sources of high E.M.F. such as highcurrent cables, motor starters, or S.C.R.variable speed drives. Avoid mounting in highvibration areas such as handrails and rotatingplant. Use rubber absorption mounts ifmounting in light vibration areas. Removethe P.C.B. assembly before drilling cable andconduit entry holes.

TRANSDUCERSelecting a suitable position to mount thetransducer on the vessel is the single MOSTIMPORTANT step. Please read all of theinstallation guide and contact your Hawkrepresentative if you have any doubts orquestions. The mounting position must allowfor the blanking distance. That is, thetransducer face MUST be at least the blankingdistance away from highest the product levelin the bin, tank, or silo at all times. Refer totable 4 below.

Where possible use the conservative valuesand increase this distance by 50% if there isfoam, dust, steam, or condensation in thevessel being monitored. Refer "BlankingDistance" page 3. If using a flange mounting,use a rubber or neoprene gasket and washers.If using a nipple mounting, ensure that themounting bracket is >6mm (0.24 in) from therear of the transducer. Do not over tightenthe lock nuts. When using a focaliser cone,ensure that it protrudes at least 50mm (2 in)into the vessel. If the transducer needs to bemounted above the roofline, use anappropriate standpipe or nozzle. Refer figures7 page 8 and figure 16 page 12. Use commonsense when selecting the mounting position.A clear line of sight from the transducer tothe product being monitored is preferred.

Cone radius = total height x h% x rcone height 1

Percentage of volume = total height x h% x 1/3πcr2 x 100 Refer example 1 below.total volume 1

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

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 rcone height 1

Percentage of volume = total height x h% x 1/3πcr2 x 100total volume 1

Where h% is the percentage of total height and cr is the cone radius at the scaling point beingcalculated.

Cone Radius = 12m x 25% x 3m = 2m4.5m 1

Percentage Volume = 12m x 25% x 1/3π2m2 x 100 = 4.94%254.6m3 1

Therefore scaling point 6 would be entered

Referexample 2page 29.

Therefore, at 25% of vesselheight the scaling point is4.94% of total volume.

6: 25.0 > 4.9

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 100total volume 1

Where h is the percentage height at the scaling point being calculated.

Percentage of Volume = (12m x 55% - 4.5m) x πr2 + 42.4m3 x 100 = 39.97%254.6m3 1

Therefore scaling point 12 would be entered

Flow - Parshall Flume

Use the following table for calibration of RMAfor flow measurement in Parshall flume.

The basic formula is Q = KHα, where H isabsolute head (i.e., not differential head), k isa flume constant and K is a flume constantapprox 1.5.

Following table of % flow vs % head forexponents 1.5, 1.52 and 1.54.

The exponents for Parshall flumes vary between1.50 and 1.58 but are typically close to 1.50.Note that the effect of exponent accuracy isgreater at the low flow end.

This table is based on 5% head increments. Forbetter accuracy the increments can be smallerat the higher head values.

The 0% and 100% head should correspondrespectively to the low level and high level. Thisis not essential, however the % values willbecome more complicated and the 4 to 20mAoutput will have to be reconfigured if it isrequired to indicate flow.

The flume specifications are required to obtainthe exponent, and the 100% full scale value.

Note: some flume manufacturers do not providethe exponent value, but provide a table of flowvs head instead.

S01 UNITSDefines the units of measure for display andparameters.Options: metres, centimetres, feet, and inches.

S02 OUTPUT MODEDefines how vessel contents information isdisplayed.

* ONLY available on dual channel amplifiers.† Refer D Span below.

RESOLUTIONThis sets the resolution of displayed distancesfor both programming and level indication.

D SPANIf DIFF SP (differential space) or DIFF MAT(differential material) is selected as the outputmode for channel 1, D SPAN (differential span)sets the span for the 4 - 20mA output forchannel 1 and operates according to theDIFFERENCE in the measured distance ofChannel 1 and Channel 2. E.g.: If the D SPANis set to 1.00m, the analog output would be4mA when the difference betweenCH1 andCH2 is 0m, and would be 20mA when thedifference between CH1 and CH2 is equal toor greater than 1.00m. Note: the distance from the face of transducer1 to the product must be less than or equal tothe distance from the face of transducer 2 tothe product for correct operation.

S03 LOW LEVELDefines the bottom of the measurable span,and is relative to the face of the transducer.Refer figure 23, page 19.

S06 FILL RATEDefines the fill rate in the chosen units perhour, and should be set to approximately120% of the expected maximum fill rate of thevessel being monitored. For applications withvery fast fill rates (> 60m/h, 200ft/hr), EXPRESSshould be chosen. To select EXPRESS, pressand hold the button until EXPRESS isdisplayed.

S06 EMPTY RATEDefines the empty rate in the chosen unitsper hour, and should be set to approximately120% of the expected maximum empty rateof the vessel being monitored. Forapplications 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.

RST TRACKINGAutomatically sets some parameters tosoftware defined values dependant on the filland empty rates. If the APPLICATION ischanged or the FILL/EMPTY rates aresignificantly modified, you will be promptedto reset tracking.Options: YES or NO

S07 BLANKINGDefines the distance from the transducer facewhere no echo can be detected.

S06M APPLICATIONDefines the type of product in the vessel beingmonitored.

S08 DAMPINGDefines the rate of change of the displayedinformation AND the analog outputs duringfilling and emptying of the vessel. A lowernumber will give a faster response and ahigher number will give a slower response.There are two numbers displayed on the LCD,the first number is the damping value forfilling, and the second number is the dampingvalue for emptying.S09 RELAYSThere are programmable relays in the RangeMaster. Each of them can be independentlyprogrammed switch on and off at userselectable set points.If you have a dual channel Range Master, youfirst need to assign the relay function. Thefunctions are XDUCER1, XDUCER2, DIFF, andAVERAGE.

XDUCER 1 or 2Assigns the relay to a transducer. Relays willswitch depending on the measured level fromthe assigned transducer.

DIFFRelays will switch depending on thedifferential of channel 1 and channel 2.

AVERAGERelays will switch depending on the averageof channel 1 and channel 2.The operating modes for the relays are OFF,EN LEV, DEN LEV, EN TEMP, DEN TEMP, ENGAIN, and DEN GAIN.

OFF: Relay is de energized at all times.

EN LEV: Relay is NORMALLY ENERGIZEDand will de energize when the product level in the vessel risesabove L1 and re energize whenthe level falls below L2. L2 mustbe ≥ to L1. Distances L1 and L2 are distances from the face of the transducer.

DEN LEV: Relay is NORMALLY DE ENERGIZED and will energize when the product level in the vessel rises above L1 and de energize when the product fallsbelow L2. L2 must be ≥ to L1. Distances L1 and L2 are distances from the face of the transducer.

EN TEMP: Relay is NORMALLY ENERGIZEDand will de energize when themonitored temperature rises above T1 and re energize whenthe temperature falls below T1.

DEN TEMP: Relay is NORMALLY DE ENERGIZED and will energize when the monitored temperature rises above T1 andde energize when the temperature falls below T1.

EN GAIN: Relay is NORMALLY ENERGIZEDand will de energize when the system gain rises above G1 andre energize when the system gainfalls below G1.

DEN GAIN: Relay is NORMALLY DE ENERGIZED and will energize when the system gain rises above G1 and de energize whenthe system gain falls below G1.

RELAY CYCLING/ALTERNATESet Alternate to "ON" to enable relay cycling.Relay cycling allows the user to program relay1 and relay 2 to alternate their set pointssequentially. This means that during the firstfill/empty cycle relay 1 and 2 will switch attheir programmed set points. During thesecond fill/empty cycle relay 1 will switch atthe set points for relay 2, and relay 2 willswitch at the set points for relay 1. At eachsubsequent fill/empty cycle, the set pointsfor relays 1 and 2 will alternate. This istypically used for pump cycling operations.

S10 LOW OUTPUTDefines the analog output that correspondsto the LOW LEVEL. The default is 4mA andcan be adjusted between 0 and 20mA.

S11 HIGH OUTPUTDefines the analog output that correspondsto the HIGH LEVEL. The default is 20mA andcan be adjusted between 0 and 20mA.

S12 SIMULATESimulate allows the user to test the analogoutput and relay set points by simulatingchanges in the measured distance. The displaywill show the simulated distance from thetransducer on the left-hand side, and thecorresponding product quantity on the right-hand side. The analog output will changeproportionally and the relays will energizeand de energize at their respective set points.

S13 TEMPERATUREThe Range Master can be setup to compensatefor changes in the temperature within thevessel. The temperature source (S12M) isselectable. The options are FIXED °C, FIXED°F, SENSED °C, and SENSED °F. The ambient

temperature (S12A) is adjustable. If FIXED isselected, S12A should be set to the normaloperating temperature within the vessel, andif SENSED is selected, S12A should be set tothe actual temperature within the vessel attime of selection.

FIXED Assumes that the selected temperature is the ambient temperature at all times, and themeasured distance is not compensated for changes in temperature.

SENSED The Range Master measures thetemperature and compensates the measured distances for changes in temperature. The selected temperature is assumedto be the ambient temperature at the time of selection and is used as a 1-point calibration.

S14 FAILSAFEAssigns default analog output in case of a lossof echo or system fault, and a time delaybefore entering FAILSAFE condition. Theanalog output (S13M) is selectable, and thetime delay (S13T) is adjustable from 0:00:10to 7:59:59.The options are:

LAST KNOWN The last know analog value before entering failsafe condition.

MIN LEVEL The analog output will rampdown to 4mA.

MAX LEVEL The analog output will rampup to 20mA.

<MIN LEVEL The analog output will rampdown to BELOW 4mA.

>MAX LEVEL The analog output will rampup to ABOVE 20mA .

S15 CAL CODEChanges the default code for entry to setupfrom 0 to any number between 0 and 999.This allows the user to restrict access to thesetup parameters of the Range Master. Ifchanged, the assigned number MUST beentered to gain access to all setup parameters.IF you change the CAL CODE, make sure yourecord it.

TROUBLESHOOTING

False High Level Indication:

If the RangeMaster displays a false high level,particularly at a low liquid level the mostlikely cause is excessive transducer ringdown.

Transducer Ring Down Explained:After the RangeMaster sends a pulse to thetransducer, there is a definite period of timebefore the transducer stops vibrating. Thisis termed transducer ring down. When theRangeMaster is turned on for the first time,the transducer is pulsed several times, andthe ring down characteristics are stored inmemory. This stored information is usedduring normal operation to reduce the effectof ring down on valid echo detection.

The trace diagrams show typical tracesmeasured using the test pins on theRangeMaster circuit board . As can be seen,the ring down is significantly different foreach trace. The large ring down shown inFigure 27 above, could be interpreted as apotential valid echo and cause a false highlevel to be detected. This is because the gainof the RangeMaster is raised at low levels todetect the lower amplitude echo from theproduct surface. (Echo amplitude is generallyinversely proportional to the distance fromthe transducer), causing the ring down toappear large.

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 producton cone.

3. Check that cone is not missing or damaged.4. Check that transducer is installed correctly.

CONNECTING an OSCILLOSCOPE

Top Trace (Ch 1)Amplitude 2V per division.Sweep time 5mS per divisionNote: Depends on maximum distance betweenTransducer and the Low level being measured.Typically 5-10mS per division.

Bottom Trace (Ch 2)Amplitude 0.2V per division

TEST POINT LOCATIONS

The operation of the RangeMaster can beobserved with the aid of an oscilloscope. Onthe lower right corner of the circuit boardare pins to connect an oscilloscope.

The two traces of the oscilloscope areconnected to the WINDOW pin and the ECHOpin. The ground is connected to the GND pin.The trigger is connected to the TRIGGER pin.Note: On Dual channel amplifiers, theoscilloscope will display the waveforms forCH1 or CH2 alternately using the "TRIGGER"pin. If you want to display only CH1 or CH2,use the T1 pin to trigger for CH1 only, or T2 totrigger for CH2 only.

A dual trace storage oscilloscope isrecommended but not essential. A nonstorage oscilloscope can be used. Figure 29shows the two traces produced on theoscilloscope.

The top trace is the 'window' trace. The'window' indicates the position theRangeMaster considers the correct echo, andtherefore level to be. For an echo to beconsidered it must larger than a softwaredefined threshold. If an echo is greater thanthe threshold a register is placed on the'window' trace.
