• This session is designed to provide a working method from the moment the 3DLevelScanner is installed and wired to the point it is configured and providing correct measurements

• At this point the Installer or person who configures the 3DLevelScanner has all the information needed:• Correct vessel drawings and dimensions• Location of the 3DLevelScanner• Complete IPF with all relevant data• Wiring and Power connections to the 3DLevelScanner• And a customer’s computer to be used for the daily

operations

Work Procedure


• Step 1:• Use the actual drawing and measurements of the vessel to

confirm all numbers• Use the locator to find the best location for the

3DLevelScanner• Compare the actual installation with the Locator results• Verify the IPF numbers• Complete missing information if needed

• When the 3DLevelScanner is not mounted according to APM recommendation, there is no way to guarantee performance and is advice to correct the installation

Work Procedure


• Step 1: Locator

Work Procedure


• Step 2: • Connecting to the 3DLevelScanner from the customer’s

computer, this is to verify that the wiring is correct and more important that the 3DLevelManager is installed correctly and there are no driver’s/computer issues

• Running the 3DLevelManager and connecting to the Scanner

Work Procedure


• Step 2: Getting to know the 3DLevelManager

Work Procedure


• Step 2: 3DLevelManager Technician mode: techAPM

Work Procedure


• Step 2: 3DLevelManager

it’s position, limited between -1m to +1m (-3.28ft to +3.28ft)

• Steepest Material Slope• Set the angle of repose,

recommended numbers between 30 to 45 degrees, default – 35 degrees

Work Procedure


• Step 2: 3DLevelManager Configuration tabs• Extended Calibration:

• False Echo Mapping:• Automatic or manual scan of a

defined part of the vessel to delete false echoes

• Featured with the option to delete all mapped false echoes

Work Procedure


• Step 2: 3DLevelManager Connection Status and measured parameters• Display the connection status and allow a

reconnect operation in case of failure• Level / Distance – shows the Average, Min. and

Max. measurements• Volume – displays the volume in %• Mass / Volume – display calculated

measurements according to the scanner’s settings

• Temperature• SNR – a calculated value of the signal to noise

ratio• Output Current

Work Procedure


• Step 3: Connecting to the 3DLevelScanner• Different connection methods: HART,

RS-485, GSM, GPRS, TCP/IP• Configuration:

• Serial port• Polling Address: 00 to 63 or

Multiple• Communication log: Normal or

Verbose (collect more data)• Further Configuration – depending on

the communication method, additional info might be required

• Press Connect to establish communication to the 3DLevelScanner

Work Procedure


• Step 4: Configuration• Press Tools

Configuration Wizard or press F4

• Set Device Name• Length units (m, cm, mm,

ft, inch)• Temperature (Fahrenheit

or Celsius)

Work Procedure


• Step 4: Configuration• Set Vessel’s dimensions• Top / Bottom shapes – Flat,

cone, Pyramid or Dome• Center shape – Cylindrical

or rectangle

Note: In Top and Bottom Shapes, the Diameter refers to the Top or Bottom Diameter accordingly

Work Procedure


• Step 4: Configuration• Set Scanner position• Center of Axis is set to the

center of vessel• X and Y are the distance

from the center axis• Z is the mounting level of

the scanner measured from the bottom of the vessel

• The bottom “Set Device Z-Position to Ceiling” will set the Z value to the top most position of the vessel considering the X and Y values

Work Procedure


• Step 4: Configuration• Horizontal Angle – the

scanner must point to the center of the vessel, press the button “Set Horizontal Angle Towards Center”

• In case where the scanner is not pointing the center and it is not possible to physically mount it in that way, it is possible to adjust the angle manually

Work Procedure


• Step 4: Configuration• Filling Points

• Set maximum 10 filling points, the Z value must match the actual location of the filling point

Work Procedure


• Step 4: Configuration• Emptying Points

• Set maximum 10 emptying points, the Z value must match the actual location of the emptying point

Work Procedure


• Step 4: Configuration• Basic Settings

• Media Type – set the working frequency of the scanner

• Process Condition – Not to be changed

• Full and Empty Calibration levels are to be set according to the customer’s requirement, note the0.5m (1.6ft) of scanner’s dead band

Work Procedure


• Step 4: Configuration• Basic Settings

• Filling and Emptying Rates – must correspond to the actual process in the plant, values in Tons per hour

• Maximum Capacity – values in Ton, should represent the vessel’s capacity

Work Procedure


• Step 4: Configuration• Linearization

• Linear, Automatic or customized table

• Can be set with various mass or volumetric units

• Up to 32 points when setting the table manually

• Press OK or Upload All to set the parameters in the 3DLevelScanner

Work Procedure


• Step 5: Extended Calibration· Dumping Time – set the amount of data

the scanner accumulates in order to predict the material behavior, default value is 300 seconds

· Offset – set the scanner’s Z position offset from its settings in the configuration wizard, the values can be ± 100cm (40”)

· Steepest Material Slope – set the maximal angle of repose according to the material characteristics.

Work Procedure


• Step 6: Grades Analysis• Collecting data from the

3DLevelScanner:• Grade level• False echoes• Threshold

• Allowing continuous analysis• Enables Multidrop analysis

• Press Start to begin the grades process

• Note: it is recommended to perform the grades analysis when the SNR is high (above 13dB)

Work Procedure


• Step 6: Grades Analysis• Viewing the returned echoes allows to decide

whether an echo is false or real• The Grades helps to decide how to do the False

Echoes Mapping• Horizontal axis – Distance of echo from the scanner• Vertical axis – Relative Power level – Grade

Work Procedure


• Step 7: Advanced Parameters· Mechanics Type:

· I – 3DLevelScanner I· II – 3DLevelScanner II

· Transmission power to be set as High· False Echo Sensitivity – Ratio between

the mapped false echo and true echo· Activate Extrapolation – used with MV

models for mathematically enhanced 3D image, Inactive by default

· Grades Filter: attenuates measured grades that are 70% lower than the maxima

· Top Dead Band: Discard – don’t measure above Full Calibration line. Don’t Discard – Measure above Full Calibration line

Work Procedure


• Step 7: Advanced Parameters· Restrain Coefficient - Defines preference

of echoes between every pair of echoes (along the grades graph) above the steepest material slope, default is 10%

· Max. Emptying Rate, Max. Filling Rate and Max. Capacity are according to the settings in the configuration wizard

· Window Size – Size of window around the group of chosen echoes – to be set to 100m (328.084ft)

· CFAR sensitivity – Control the automatic threshold sensitivity above the noise (default 10 dB)

Work Procedure


• Step 7: Advanced Parameters· Good SNR [dB] – Set the threshold of the

good SNR. Above this level, the sensor increases its measurement speed

· Minimal SNR [dB] – The lower SNR threshold. Below this level the sensor does not measure and the reading stays stable.

· Exceeding Filling Rate After False Echo Loss – If set to Yes, the scanner will look for an echo at high level according to: Time of echo loss multiply by three times the filling rate

· Use Compressed Pulses: function for distances above 9m from the scanner

Work Procedure


• Step 7: Advanced Parameters· Side and Bottom margins are extensions

of silo size to allow additional information to be received

· Auto False Echoes Recognition – Ratio between the automatic false echoes and the true echoes, default is 1.2, set to 0 if Pulse compression is turned on

· Note: Press “Upload All” after changes were made to take affect in the scanner

Work Procedure


• Step 8: False Echo Mapping· After all settings are completed and the

scanner is reading the material surface, or there is a known interference inside the vessel that creates a strong false echo (based on grades analysis and visual confirmation), it can be removed manually in the False Echo Mapping.

· The options are: Scan, Manual Scan and Reset all false echoes mapping

· Scan – allow to select the span of distances to remove all false echoes

· Manual Scan – in addition to the distances, it allows the user to set the level of threshold of the false echoes

· Reset – remove all saved mapping
