GENERAL DESCRIPTION
Process

Air
Acoustic
The SmartSonic Acoustic Wave Transmitter is designed for high accuracy level measurement of a variety of liquids. The SmartSonic Integral can also be used for Open Channel Flow Measurement.
PRINCIPLE OF OPERATION
The SmartSonic Transmitters consist of two main components:
• The Electronics
• The Sensor (Transducer)
The transducer contains a piezoelectric crystal that converts an electrical signal from the electronics, into acoustic (sound) waves. These acoustic waves are directed through the air toward the process media surface. They are then reflected off of this surface and returned to the transducer. The piezoelectric crystal then converts the received waves into an electrical signal which is analyzed by the electronics.
The time difference between the transmitted wave and the received wave is proportional to the distance from the face of the transducer to the process media surface. This distance is used by the electronics to calculate level or open channel flow in the units selected by the operator.

MOUNTING GUIDELINES
MOUNTING INSTRUCTIONS
Precautions:
• Ensure that the sensor is mounted in an area that meets the stated temperature, pressure and technical specifications.
The transmitter must be mounted in such a way, as to avoid the process fluid level from entering the Dead Zone.
If the level enters the Dead Zone, an error will occur, and the transmitter will not measure the fluid level
The sensor needs to be mounted as far away as possible from processes that can interfere with the Acoustic Wave. This example shows a fluid filling inlet.
While the narrow wave diameter of the Kenco Acoustic Wave Transmitters allows you to mount the sensor closer to the vessel wall, than other Ultrasonic transmitters, it is recommended to mount the sensor at least 1.64 feet away from the wall.
The sensor must be mounted perpendicular with the process fluid level. Even the slightest mounting off perpendicular will affect the measurement. Anything over 4º will usually result in a loss of echo or at the very least, an inaccurate reading
• Ensure that high voltage (ac) sources or cables are at least 1 yard away from the sensor and its cable.
• Installation and Operation of this transmitter must conform to the National Electric Code and any applicable local
codes.
Direct Mounting of the Sensor to the Tank
1.) Open the top of the tank
2.) Feed the free end of the sensor cable from the inside of the tank, through the 1” NPT coupling attached to the top of the tank (customer supplied).
3.) Keep feeding the cable until the sensor threads are touching the coupling. Screw the sensor threads into the coupling.
Page 4
Mounting the Sensor to a Flange

JP1
1.) Feed the free end of the sensor cable through the 1” NPT threaded connection on the flange. Feed the cable from the process side of the flange
2.) Keep feeding the cable until the sensor threads are touching the inside of the flange. Screw the sensor threads into the 1” NPT threaded connection on the flange.
3.) Bolt the flange to the top of the tank. Use a soft gasket.
Mounting the Transmitter (Electronics)
1.) Drill (2) holes, 2.75” apart, onto the desired mounting surface. Install (2) screws into these holes.
2.) Attach the mounting plate to the SmartSonic, using the (4) screws provided.
3.) Mount the SmartSonic onto the desired mounting surface, using the slotted holes on the mounting plate and the (2) screws on the desired mounting surface from Step #1.
WIRING
It is recommended that conduit be installed onto the ½” NPT connections (C1 thru C4) on the electronics housing. Seal drain fittings should be used to prevent moisture from entering the transmitter. In high humidity areas, use breather drains to minimize moisture intrusion.
All wiring, conduit, and fittings must conform to local electrical codes for the location selected. If the transmitter is to be used in a Hazardous Area, the applicable sections of the National Electric Code must be followed as well.

Sensor cable side
Wiring Connections
In order to connect the wiring, remove the ribbed faceplate on the front of the electronics, using a 7/64” (3mm) Allen wrench. Ensure that the cover is reinstalled, with the gasket in place, after completing the wiring. Refer to the drawing on the previous page for the location of the wiring connections and cable entries.
NOTE: Power must be off when wiring the electronics. Damage and/or injury may occur if power is applied during wiring.
Wiring the Sensor Connections
The sensor uses a custom 5-conductor cable between the sensor and electronics. The cable comes with a cable connector, which can be used to extend the length of the cable. Make sure that you use Helukabel p/n 16028. Use of any other cable may damage the sensor, or interfere with the signal.
If you are only using the standard 16.4 ft. of cable supplied attached to the sensor, or the non-connector end of an extended cable:
1.) Remove the cable connector from the sensor-side of the cable (the male plug). Skip this step if you are using the non-connector end of an extended cable.
2.) Thread the cable through aperture (C1 – see wiring drawing on page 5) located on the right side of the SmartSonic electronics base.
3.) Connect each wire by color, to the appropriate screw terminal on connector JP5. If the cable contains multiple black wires, connect as follows:
JP5 Post Color
1 Green (Black 1) 2 Brown (Black 2) 3 Blue (Shield) 4 White (Black 3) 5 Yellow
If you are using the cable connector, follow these directions:
Nut
1.) Unscrew the nut holding the cable connector together.
Loose cable side
2.) Disassemble the “loose cable side” of the connector.
3.) Disconnect the “dummy cable” wires from the connector, and connect the wires from the extended cable (supplied separately). The blue wire is connected to the cable shield. Make sure that the wires match exactly. If you aren’t sure, disassemble the “Sensor cable side” connector and match up the pins to the wire color. If you have any questions, please contact Kenco. Do not apply power unless the connector is wired correctly.

Wiring the Digital and Analog Communication Cables
SmartSonic data can be monitored on a PC or PLC via RS-485 (MODBUS RTU) digital communications, when connected to JP22. You can also monitor a 4-20mA output by connecting to JP32 (the 4mA and 20mA settings are discussed in the CALIBRATION section).
1.) Thread the connection wires through aperture C2.
2.) Connect each wire to the appropriate screw terminal at connection block JP22 (MODBUS) and / or JP32 (4-20mA). JP22 connections are as follows:
JP22 Post Wire
1 B (TxD) 2 A (RxD) 3 Ground
JP32 connections are as follows: Post 1 (+); Post 2 (-).
JP32 Post Wire
1 + 2 -
Wiring the Power Connections
1.) Thread the power wires through aperture C4
2.) If you have 100-230Vac power, connect each wire to the appropriate screw terminal on JP1 as follows:
JP1 Post Wire
1 Neutral 2 Hot
GND Ground
NOTE: If you are using 100-230Vac leave the red and black wires connected to JP2.
3.) If you have a 24Vdc power source, disconnect the red and black wires from JP2, and connect your power wires:
JP2 Post Wire
1 + 2 -
NOTE: Use either JP1 or JP2. Do not connect external power to both.
Wiring the Relays
1.) Thread the power wires through aperture C2 (DC Power) or C4 (AC Power). C3 may not be available when using conduit.
2.) Connect each wire to the appropriate screw terminal (see wiring drawing on page 5).

Default Screen
As soon as SmartSonic is fully installed and powered on, the LCD displays the default screen. The default screen provides continuously updated measurement readings and displays the current settings for some functions (either the default settings or the settings selected from the main menu). The relay number is displayed for each activated relay. You can toggle between display indication types, such as: level, distance, volume and others, by using the SmartScan Main Menu.
The tank graphic in the default screen gives an approximate visual indication of the current level of the tank contents, while the numerical area gives the exact reading. If the level enters the dead zone, the numerical area displays FF FFF. If the tank is empty, the numerical area displays the tank height. 000000 may be displayed temporarily while SmartSonic is taking a reading. You can refresh the reading by pressing the ENT and BACK buttons simultaneously.
NOTE: By default, the displayed value is in meters, and gives the distance measurement, meaning from the sensor face to the level of the fluid. The measurement indication mode and measurement unit can be changed, as described in Setting

NOTES: After you select any option the “Tank Graphic” will cycle a few times. Wait until one of the options starts to blink before proceeding to the next step.
When you change an option, a flashing “Ar. 5” may appear. This is just to remind you that the option you just selected may affect the Relay or 4-20mA Settings, and that you need to review these settings.
Setting the Indication Mode
The first function in the Main Menu is the Indication Mode. This sets the type of measurement. The options are:
• DIST: The displayed reading represents the distance from the sensor face to the process media.
• LEVEL: The displayed reading represents the level of the process media measured from the bottom of the vessel.
• FLOW: The displayed reading represents the flow rate through the configured Flume or Weir.
• DIA: DO NOT USE
Setting an Indication Mode enables you to toggle between other indication types as well, using the BACK and NEXT buttons as described in the table below: For example, if the unit is configured for Level, the BACK and NEXT buttons will toggle between Level and Distance.
Indication Toggle Selections (BACK / NEXT Buttons)
Distance Distance / Level
Level Level / Distance
Flow Flow / Level / Distance / Totalization (High) / Totalization (Low)
Totalization indicates the total accumulative flow. It is expressed in 10 digits. The first 5 digits (High) are shown as H00000, and the second 5 digits (Low) are shown as L00000. This function will be described later in this manual (Additional Features).

Setting the Measurement Mode
This function is used to select the units used for the display. The following measurement options are available:
• METER (default), INCH, or FEET: Select one of these options for Level or Distance measurements
• M3/HR or G.P.M.: Select one of these for Flow measurements
After setting the measurement unit, the selected unit flashes on the display whenever you enter numerical values during the setup procedure. The values for functions, such as Relay, will be displayed in the selected measurement unit.
Press / Action Display Description
Move between the available options.
and
For Example
Select the desired option. This will show on the display for a few moments, then return to the Main Menu
Go to the next function (Relay Values)
NOTE: If you select METER any relevant flow measurement will be in metric units (M3/HR). The opposite also applies, so that if you select M3/HR, any relevant distance or level measurements will be in meters. If you select INCH or FEET, the flow measurements will be in G.P.M.. If you select G.P.M., any relevant distance or level measurements will be in inches.
If you select METER when using a FLOW unit configured to show G.P.M., the METER sign will flash rapidly for a few seconds. If you approve the selection by pressing ENT, the flow unit will change to M3/HR.
Setting the Relay Values
The relays in the SmartSonic Remote are SPDT (Single Pole, Double-throw). This means that each relay has (3) connections:
• Normally Closed (NC)
• Common (C)
• Normally Open (NO)
In the SmartSonic, the term CLOSED means that the relay is de-energized. In this state the NC and C terminals are closed (connected), and the NO and C terminals are open (disconnected).
The term OPEN means that the relay is energized. In this state the NC and C terminals are open (disconnected), and the NO and C terminals are closed (connected).
In the event of power loss to the SmartSonic, the relays automatically go to the CLOSED state (NC & C are connected; NO & C are disconnected). Make sure that any auxiliary equipment connected to the SmartSonic relays, will be in a safe condition upon loss of power to the SmartSonic.
You can set the relays to (5) different indication modes:
• Level
• Distance
• Flow
• Volume
• Totalization
Page 12
Volume and Totalization should only be configured after setting the Volume/Totalization options in the Additional Features Section later in this manual. The following are the relay setup options:
Indication Mode Relay Mode
Distance Distance / Level
Level Level / Distance
Volume Volume
Flow Flow / Distance / Level
Totalization Flow / Totalization
For example, if the SmartSonic is set to FLOW Indication Mode, the relay can be set to Flow, Distance or Level values. Each of the (5) relays in the SmartSonic allows you to define OPEN and CLOSED values, enabling its use for functions such as triggering an alarm or controlling pumps. As an alternate, Relay #4 can be configured to report error messages, and Relay #5 can be configured for a Flow Totalization pulse (see instructions later in this section).
The relay values function as follows:
• OPEN: The relay energizes if the level measured in the vessel is higher than the programmed OPEN value.
• CLOSED: The relay de-energizes if the level measured in the vessel is lower than the programmed CLOSED
value.
The default value for the OPEN and CLOSED functions is 0. The indication mode default value is LEVEL.
NOTE: The CLOSE value must be at lease 1 inch lower than the OPEN value. An error (Err. 3 or Err. 10) will appear if this is not the case. If a relay value greater than the tank height is entered error (Err. 7) will appear

This screen allows you to enter up to (5) digits of Low numbers of flow values.
In the example above, the relay values were configured in the following way:
• 00001 was entered in the High numbers (H = 1)
• 20000 was entered in the Low numbers (L = 20,000)
This would mean that the OPEN value was set at 120.000 (G.P.M. or M3/HR)
NOTE: The same procedure is used for the Volume and Totalization Modes. The units for the Totalization Mode are
Gallons when the selected Measurement Unit is G.P.M. The units for the Volume Mode are the same used when entering the Volume Strapping Table (see Additional Features Section later in this manual).
Setting Relay #4 to Report Errors
This allows you to use Relay #4 as a trigger to set an alarm if the unit has a “Lost Echo”, indicates a level higher than the Tank Height, or when the level moves into the “Dead Zone”. Once the error mode is enabled, and an error occurs, the relay will de-energize and the error message will show on the display. The following are the error displays:
• EE EEE: Loss of Echo, or measurement value is greater than the Tank Height.
• FF FFF: Process media is in the “Dead Zone”.
The relay will be energized as long as the unit is functioning properly.
Repeat the previous steps to set a CLOSED value for the relay.

Setting Relay #5 for Flow Totalization Pulse
You can choose to set Relay #5 for flow totalization pulse or to remain in normal set-up mode. This option enables you to reserve the accumulated value gathered by the unit, by using an external counter. In this way the total value will be reserved even if the unit will be replaced. Once set for this option, the relay will generate a pulse per Xm^3 or Gallons of flow depend on the value that you have selected from the following list of optional values (you can define the X value): 1, 10, 100, 1000, 10000, 100000. An electrical pulse will be generated whenever the relay total flow value will be larger than the value selected from the list. You can also choose a pulse width between 20 to 2000 milliseconds with a resolution of 10 milliseconds to match your equipment requirements. For example, the relay will generate a pulse with a duration of 1000ms and each time the value of flow will reach 10,000 M^3 (provided that this value was selected from the optional list of values).
Move to Relay #4, then press ENT.
Choose Err En to enable error alert; Choose Err dS to disable error alert.
NOTES: Prior to setting Relay #5 for pulse indication, you should configure the SmartScan for Totalization (see Additional Features Section later in this manual).
To configure Relays #4 and #5 to work in a normal setup, select OPEN or CLOSE mode and enter the required parameters. When configuring Relay #5 as tOt En (Totalize Enable), the active options are tOt En and tOt dS (Totalize Disable). To go back to normal work press tOt dS.
The result of the totalization amount is updated every 30 seconds.

Setting the Application Type
This displays the application function of the transmitter. Either Liquid (Level / Distance mode) or Flow (Flow Mode).
Setting the Operation Mode
The Operation Mode function enables you to set SmartSonic Remote to compensate for environmental conditions that affect the measurement readings.
For liquid applications, each mode determines the reaction time required for SmartSonic Remote to recalibrate when there is a change in the environmental conditions. Depending on the specific requirements for your application, you can select a mode that provides faster readings but with less precision (by performing a smaller number of calculations per cycle), or slower readings with a greater degree of accuracy (by performing a larger number of calculations per cycle).
Three modes are available for SmartSonic Remote. Each mode is recommended for use as follows:
F : Recommended in the following conditions:
v Level/Distance Change: 0 – 0.65 ft/sec v Wavy surfaces v Slow filling/emptying rate v Applications where the sensor is installed near the tank wall
Used to select the desired value. Press ENT when finished.
v Level/Distance Change: 0 – 1.3 ft/sec v Wavy surfaces v Slow filling/emptying rate v Applications where the sensor is installed near the tank wall
F : This mode is suitable for applications where a fast reading is more important than
precision. A reading will be displayed within a short time, even if the signal processing procedure was not completed.
F Recommended in the following conditions:
v Level/Distance Rate Change: 0 – 3.3 ft/sec v Foamy top surface v Presence of agitation v Presence of vapor v Applications requiring very fast readings
: (Twice as fast as STORAGE I): Recommended in the following conditions:
Page 18
NOTE: STORAGE I and STORAGE II are not suitable for measuring liquids containing foam, since these modes cannot perform signal processing.
The operation modes are not relevant for flow applications. If one of the STORAGE I, STORAGE II or PROCESS options is selected when SmartScan is in FLOW application mode, an warning
message is displayed and SmartScan reverts to distance mode. You must then reset the unit to flow mode.
Press / Action Display Description
or
Move to STORAGE I (flashing). Select one of the three modes: (STORAGE I, STORAGE II, PROCESS)
Setting the Sensor Offset
SmartSonic Remote takes measurements from the tip of the sensor. However, when the sensor is located at a point that is above or below the true height of the tank, you can use the MAN function to enter the difference. This may be required, for example, if the sensor is installed at the top of an external pipe, or at the base of an internal pipe in the tank.
When the sensor is located above the tank height, the difference must be subtracted from the actual measurements, so the offset distance is entered as a negative value and vise versa. The maximum permitted offset value is 2.0 m and the minimum permitted value is -2.0 m. Values can be entered in meter units only.

Page 19
Setting the Scan Distance Values (False Targets)
Up to eight interfering signals (false echoes) can be located by SmartSonic Remote and stored in its memory. The false echoes, which may be caused by obstructions such as a tank agitator or a side wall, can generate false readings and so interfere with the true scanning of the tank contents. Defining interfering signals is done while the tank is empty.
Each scan distance reading is stored as an interfering signal until a reading is achieved that indicates the true echo. If eight interfering signals are already stored and a ninth reading is received, the first value stored is deleted and the new one saved.
The scan distance function is accessed from the default screen. AUTO. CAL is displayed at the base of the display screen during the scan distance operation, indicating that you are working in scan distance mode.
NOTE: The reading of the actual target height may not be exact; for example, a target height of 6 feet may give a reading of 5.998.

OPEN CHANNEL FLOW MEASUREMENT
and
This section describes how to set the flow measurement parameters for Open Channel Flow measurement. It also covers the flume/weir codes used when selecting the flume or weir of your application.
The PARSH.FLUM function in the main menu enables you to select one of the preset flumes/weirs settings for flow measurements.
When setting flow-measurement parameters, the flume/weir type value (X) is entered first, followed by the letter (U) or (E) as an indication for American or European open channel flow standard and followed by the code value (FF) that represents the appropriate flume/weir dimensions, in the following format: . The default is European standard. The open channel types and codes are described in later in this section.
If you wish to insert custom flume measurements, you must enter 0.E (or U) 01 for this function. This entry will automatically initiate an additional menu function (Pr 1), enabling manual insertion of custom flume values in an accordance table, as described in the section titled Additional Features.

Manually Inserting Strapping Table Values
The Pr 1 function enables you to manually create a strapping table of distance points for either volume calculations or custom flume measurements.
The strapping table is used for manual insertion of distance/volume values when IND 1 was selected as the value for Pr 0, Manual insertion is applicable when the ratio between the distance and volume of the tank is known or for applications such as custom-shaped tanks. Up to 24 linear points can be entered in the strapping table, starting from the smallest distance and largest volume for point 1 (which is the closest point to the sensor). The distance should increase and the volume decrease with each subsequent entry.
The strapping table automatically enters custom flume mode after .001 is entered as the PARSH.FLUM value in the main menu. In this mode, the table is used to manually insert up to 24 distance/custom flume measurement values, in the same way as for distance/volume values. Any custom flume measurement can be entered, as long as the maximal value entered is the measurement of the distance between the sensor and the flume.
NOTE: You can exit Pr 1 at any time by pressing the ESC button. However, it is recommended that you enter at least 8 points for this function. Values are entered in DISTANCE or LEVEL units.
When working in custom flume mode, exiting Pr 1 returns you to the main menu

Setup for the second point. Repeat the previous steps to enter at least 8 points. Press ESC to exit.
Semi-automatic Inserting Strapping Table Values
The Pr 2 function enables you to create a strapping table for distance/volume values using distance values measured automatically by SmartScan, rather than entered manually as described in the previous section. This method enables more accurate volume indications than the manual method, but entails slower calibration due to the need for additional instruments, such as a flow meter.
This function should be started when the tank is full, so that point 1 (P 1) is calculated for the smallest distance/highest volume. The subsequent points are calculated as the tank empties.
NOTE: You can exit Pr 2 at any stage by pressing the ESC button. However, it is recommended that you first enter at least eight points for the function. The same strapping table is used for functions PR 1 and Pr 2. Any change made to either of the functions will be applied to the one mutual table. A minimum of (8) strapping points should be entered into the table to make accurate readings. Maximal number of strapping points to be entered is twenty-four (24).

Entering a Coefficient for Readings
Then
The Pr 3 function enables you to enter a coefficient value, K, which can be used for three different options. For each option, the entered K value is used by SmartScan in the following formula: Y = K(X)
F The variables represent the following values:
• Y = Result according to the new measurement unit
• K = The factor difference between the previous measurement unit and the current unit
• X = Result according to the previous unit (such as meters, feet or inches)

Configuring Height for a Cone Bottom Tank
The Pr 5 function enables you to enter the cone height for tanks that have a conical base. This may be required if you are unable to mount the sensor at the center of the tank, or if the cone is causing false echoes and consequently faulty measurements. The entered cone height value can be from a minimum of 000.000 (the default value) up to a maximum of half the tank height value.
NOTE: An Err. 1 message is displayed if the cone height (h) is more than halt the Tank Height (H) value.

Defining the 4-20mA Error Signal (3.7mA or 22mA)
The Pr 6 function allows you to define whether the following signal error indications Near Zone and Lost Echo will be active when the current output reaches 22mA or 3.7mA. The SmartScan default setting enables 22mA analog current and error messages to appear on its LCD display.
Near Zone - Whenever the level is below the defined Dead Zone message will be displayed on the SmartSonic Remote's LCD.
Lost Echo - whenever the level falls below the programmed 4mA value, or if the echo is lost, message will be displayed on the SmartSonic Remote's LCD.
Tank Empty – whenever the tank is empty or when the measured distance is higher than the tank height.
(typically in empty tanks with conic ending), message will be displayed on the SmartSonic Remote's LCD.
You can choose to enable or disable these error messages and 3.7mA/22mA analog signals as follows:
• 0: Enables 22mA signal error messages
• 1: Enables 3.7mA signal error messages
• 2: Disables signal error messages
