3 1 INTRODUCTION The SmartSonic ultrasonic level transmitters from PRINCO are excellent tools for level measurement of liquids and free-flowing solids. This manual applies to four-wire units with model numbers beginning with L4660- ST_- or L4660-SB_-. For other Princo Model L4660 Series units refer to manuals designated for Two-Wire Smartsonic and Remote Two-Wire Smartsonic. The units are available with two input power options: 85 to 255Vac and 10.5 to 40Vdc. Application The level measurement technology is based on the noncontacting ultrasonic principle. It is especially well suited for applications where, for any reason, no physical contact may be established with the material being measured. Such reasons may include corrosive attack by the process medium against the measuring device material (acids), possible contamination (sewage) or, particles of the process medium adhering to the measuring device (adhesive materials). Principle of Operation The ultrasonic level measurement technology is based on the principle of measuring the time required for the ultrasound pulses to make a round trip from the sensor to the level to be measured and back again. The sensor emits an ultrasonic pulse train and receives the reflected echoes. This intelligent electronic device processes the received signal by selecting the echo reflected by the surface and calculating the time of flight. Thus, the SmartSonic measures distance only. All other parameters, such as level, flow and volume are calculated by the unit based on this highly accurate distance measurement and on specific application data programmed into the unit by the user. The unit calculates level by subtracting the measured distance from the programmed value of the maximum measuring distance. Advanced Features The SmartSonic contains numerous features that enhance its reliability and accuracy beyond that of previous generations of ultrasonic devices. Simplified and Full Programming Modes Many basic level measurement applications can be set up using an abbreviated programming mode called Quickset. This saves the personnel involved the time required to program in the Full Parameter Access mode. The same SAP-100 plug-in display module may be used for either programming mode. The module is transportable and can be used for any number of SmartSonic units. Metric or US Engineering Units The SmartSonic may be easily set up to display either metric or US engineering units. Mathematical Algorithms for Volume and Flow The SmartSonic contains within its memory a wide array of algorithms by which it can calculate volumes based on various tank geometries, and flow rates based on various flume and weir specifications. 32-point Linearization The unit may be programmed by the user with a 32-point linearization table for applications not included in the unit s set of internal algorithms. Echo tracking and Selection The reliability of the SmartSonic is enhanced by its ability to select the correct echo if more than one echo is present. The nature of ultrasonic measurement technology is such that a device emitting an ultrasonic signal will often receive more than one return signal. The geometries of the holding vessel may diffract the return signal into different signals returning to the sensor at different times. The SmartSonic maintains a measurement window around the signal that it is tracking, disregarding other signals. If there are two signals within the measurement window, it will normally track the stronger of the two signals, but can be programmed to track the first one received. The SmartSonic can also be programmed to ignore up to two fixed objects that lie within its signal path, as well as to ignore signals within a certain proximity of the sensor or within a certain distance from the bottom of the vessel. The unit can also be set up to read accurately through atmospheres other than air. Sound travels at different speeds through different gases. This affects the accuracy of the measurement. The SmartSonic can be programmed for the sound velocity of whatever gas is present. The default setting is the sound velocity in air (343.8 m/sec, 1128 ft/sec.) Informational and Self-diagnostic Functions The SmartSonic automatically displays error codes for certain self-diagnostic functions. The codes may be interpreted according to the Error Code chart in Section 7. The SmartSonic memory also records the following information which may be read out on the SAP-100 display by the user: overall operating hours, time elapsed since last switch-on, actual temperature of transducer, and the maximum and minimum recorded temperatures of transducer. The unit will also provide data that is useful for problem diagnosis. These include the number of echoes the unit is presently receiving and the relative amplitudes of these L4660 Four-Wire Instruction Manual Page 1 of 34 Pages Rev 2, Sept 2011

4 echoes, the amplitude of the echo in the measurement window, the echo time in milliseconds and the signal to noise ratio of the echo. The SmartSonic also has a current output test whereby the unit can be programmed to put out specified currents in the range of 3.9 to 20.5 ma. Additional Flow Metering Parameters Additional flow metering parameters include headwater value and re-settable and non-re-settable totalizer values. Basic Measurement Concepts Total Beam Angle A total beam angle of 5 to 7 at 3 db is featured by most of Princo s SmartSonic transducers ensuring a reliable measurement in narrow silos with uneven side walls as well as in process tanks with various protruding objects. Furthermore, as a result of the narrow beam angle, the emitted ultrasonic signals have an outstanding focus. Deep penetration through gases, vapor and foam is ensured. Dead Band X Dead Band is a feature common to all ultrasonic level meters. The unit cannot successfully make a level reading of a material that is within a minimum distance from the transducer. It is specified as the Minimum measuring distance in the Technical Data Table. Measurement within this range cannot be interpreted. Minimum measuring distance, Xm (Close-end Blocking) Minimum measuring distance (Xm) is the distance from the transducer (determined by the design of the unit) within which measurement is not possible (dead band). This distance can be extended by programming in order to avoid possible disturbing echoes coming from fixed objects. (Close-end Blocking). Maximum measuring distance (XM) Maximum measuring distance (XM) is the greatest distance (determined by the design of the unit) which can be measured by the unit under ideal conditions. The maximum measuring distance of the actual application (H) must not be greater than XM. The unit may be programmed for a smaller maximum measuring distance in order to ignore the disturbing effects of stirrers or heaters at the bottom of the tank. D X D (meters) (meters) (feet) (inches) Diameters corresponding to a 5 beam angle. Notes on Beam Angle: The basic formula for calculating the target area of the ultrasonic beam is D=tanΘ * X where D = the diameter of the target area, X = distance from the face of the transducer to the zero level point and Θ = the beam angle of the unit (in most cases 5 degrees). The example in the above chart is calculated for a unit with a 5 degree beam angle. A distance of.122 meters has been added to the result to account for a.122m diameter transducer. As a practical matter, when determining the distance a unit should be mounted away from a sidewall or other obstruction, calculate the target diameter (D above) and divide the result by two. Make sure that the outer diameter of the transducer (not the center) is at least this far from the sidewall or obstruction. L4660 Four-Wire Instruction Manual Page 2 of 34 Pages Rev 2, Sept 2011

9 4 INSTALLATION 4.1 Liquid Level Measurement POSITION The optimal position of the SmartSonic is on the radius r = (0.3 to 0.5) R of the (cylindrical) tank / silo. (Also review Notes on Beam Angle on page 3.) OBSTACLES Make sure that no in-coming flow, or objects (e.g. cooling pipes, ladders, bracing members, thermometers, etc.), or tank wall with ragged surfaces protrude into the sensing cone of the ultrasonic beam. Two fixed objects in the tank / silo that disturb the measurement can be blocked out by the appropriate programming of the SmartSonic (Parameters P29, P30) SENSOR ALIGNMENT The sensor face has to be parallel to the surface of the liquid within ± 2 to FOAM Foaming of the liquid surface may render ultrasonic level metering impossible. If possible, a location should be found, where foaming is the least (device should be located as far as possible from liquid inflow) or a stilling pipe or well should be used WIND Intensive air (gas) movements in the vicinity of the ultrasonic cone should be avoided. A strong draft of wind may "blow away" the ultrasound. Devices with lower measuring frequency (40, 20 khz) are recommended where air flow is a factor TEMPERATURE Make sure that the transmitter will be protected against overheating by direct sunshine. Sunshade FUMES / VAPORS For closed tanks containing chemicals or other liquids which create fumes and/or gases above the liquid surface, especially for outdoor tanks exposed to the sun, a strong reduction of the nominal measuring range of the ultrasonic device may occur. This must be considered during device selection. Devices with lower measuring frequency (40, 20 khz) are recommended in these cases MECHANICAL INSTALLATION When installing units with threaded transducers, be sure to grip only by the hexagonal area above the threads and avoid over-tightening. Twisting the unit by the head can cause serious damage including breaking the wire harness connection to the transducer and breaking the waterproof L4660 Four-Wire Instruction Manual Page 7 of 34 Pages Rev 2, Sept 2011

10 seal between the transducer and the head. Once installed, the head may be turned a maximum of 360 degrees to obtain best viewing angle. There is a stop which will prevent it from being turned further STAND-OFF PIPE The structure of a stand-off pipe should be rigid; the inner rim (r) where the ultrasonic beam leaves the pipe should be rounded. Princo SmartSonic Models of S-32 with plastic transducer must not be installed in standoff pipes since its transducer face has to protrude into the tank.

11 4.2 Open Channel Flow Measurement For best accuracy, install the sensor as close as possible above the expected maximum water level (see minimum measuring range). Install the device in a place defined by the characteristics of the metering channel along the longitudinal axis of the flume or weir. In some cases foam may develop on the surface. Make sure that the surface opposite to the sensor remains free of foam for proper sound reflection. With respect to measurement accuracy, the length of the channel sections preceding and following the measuring flume and their method of joining to the measuring channel section are of critical importance. Despite the most careful installation, the accuracy of flow metering will be less than that specified for distance measurement. It will be determined by the features of the flume or weir. 4.3 Installation & Electrical Connections Screw the unit into its place. Use open end wrench for tightening. Maximum torque is 20Nm. After tightening the enclosure can be rotated to the proper position. (Safety bolt prevents rotation of more than 350 degrees. The unit may be damaged by electrostatic discharge (ESD), via terminals. Thus, apply the precautions commonly used to avoid electrostatic discharge such as touching a grounded point before removing cover. Tightening, Aligning To access the wiring terminals, loosen the screw on the side of the unit and lift the hinged cover. The 4 to 20 ma signal cable the power supply cable and the output relay cable must be separated by shielding. Units with aluminum housings may be grounded either by using the grounding screw terminal on the outside of the housing, or when using a three-wire power cable, connecting the ground wire to the internal grounding screw terminal. Units with plastic housings are insulated and have no ground terminals. Thread wires through the ½ NPT or Pg16 conduit openings and fasten to appropriate terminal block connections per drawing below for AC or DC powered unit as applicable.

20 P03: a Values Displayed-Rounding It is important to keep in mind that the instrument is measuring distance as basic quantity. Measured distance X min 2m 2m 5m 5m 10m over 10m Displayed VOL or FLOW Resolution 1mm 2mm 5mm 10mm Displayed value Displayed form x.xxx xx.xx xxxx xxxxx xxxxxx. x.xxxx : e 1 million *10 9 (exponential form) over 1*10 10 (overflow) Err4 Rounding Parameter value a Steps in the displayed value 0 1 no rounding The resolution depending on the distance can be considered as a kind of rounding that will be contained in all further values (of level, volume or volume flow) calculated. Therefore if programmed for DIST or LEV measurement the setting of P03 is irrelevant. Obviously the decimal position will be shifted with increasing value displayed. (See table at the left). Values over one million will be displayed in exponential format where the value e represents the exponent. Over the value of 1x10 10 Err4 (overflow) will be displayed. A couple of millimeters of fluctuation of the basic DIST value (e.g. due to waves) will be enlarged by the mathematical operations. This enlarged fluctuation in displaying VOL or FLOW can (if disturbing) be avoided by rounding to be set in P03. Rounding value 2, 5, 10 etc represents the steps by which the calculated value will be changed in its (one or two) last digit(s). Examples: P03=1 steps by 2: 1,000; 1,002; 1,004 P03=5 steps by 50: 1,000; 1,050; 1,100 or 10,00; 10,05(0); 10,10(0); 10,15(0) (the 0 from the steps 50, 100, 150 etc will not be displayed) FACTORY DEFAULT: 0 P04: Maximum measuring distance The maximum distance to be measured is the greatest distance between the surface of the transducer and the level to be measured. This is the only parameter that has to be programmed for each application other than distance. (However, to avoid the disturbing effects of possible multiple echoes, it is recommended to do this for distance measurement applications also.) Values of the maximum measuring distance will be displayed as below. The DEFAULT value of P04 (see table below) can also be displayed by double key pressing NEXT + DOWN. Engineering Unit Display Format m x.xxx or xx.xx cm xxx.x ft xx.xx or xxx.x inch xxx.x The factory programmed DEFAULT values the greatest distances which can be measured by the units - are listed in the table below. For the actual application, the maximum distance to be measured, i.e. the distance between the sensor and the bottom of the tank, should be entered in P04. To obtain the best accuracy, measure this distance in the empty tank with the SmartSonic by using the GET LEVEL function (by double key pressing of UP + DOWN ), provided the bottom is flat. Enter the actual measured value displayed as P04. L4660 Four-Wire Instruction Manual Page 18 of 34 Pages Rev 2, Sept 2011

21 SmartSonic Transducer material PP / PVDF Maximum measuring distance [m/ft] Transducer material PTFE Transducer material Stainless Steel S-38 6 / 20 5 / S-37 8 / 26 6 / S / / 23 S / / 39 S / / 49 Keep in mind that LEVEL (as the result of the measurement) = P04 (programmed) DISTANCE (measured by the device) The accuracy of level and all further calculated values depend on the accuracy of the maximum measuring distance of the application which is the distance between the sensor face and the tank / silo bottom. P05: Minimum measuring distance (Close-end blocking) The SmartSonic will not accept any echo within the blocking distance set here. Automatic Close-end-blocking (Automatic Dead Band control) By using the factory default value, the unit will automatically set the smallest possible close-end-blocking distance, i.e. the dead band. Manual close-end-blocking Manual close-end-blocking would be used, for example, to block out the echo originating from the bottom rim of a stand-off pipe or from any object protruding into the ultrasonic cone near the transmitter. By entering a value higher than the factory default, the minimum measuring range will be extended and fixed to the specified value. To display factory default of the minimum measuring distance press NEXT + DOWN.

A). Level measurement The far-end blocking can be used to avoid disturbing effects of stirrer or heaters at the bottom of the tanks. ma 20 ma 4 ma If the level of the medium sinks below the blocked out range: - Sub 0 will be indicated for the level and volume. - Distance value is not interpretable. - Current output will hold the value corresponding to the far end blocking level. Level Volume "SUB 0" indication below this level P06 Far end blocking If the medium level is above the blocked out range: The calculation of level and volume will be based on the programmed tank dimensions. Therefore the measured or calculated process values will not be influenced in any way by the far end blocking value. L4660 Four-Wire Instruction Manual Page 19 of 34 Pages Rev 2, Sept 2011

22 B). Open channel flow metering Far end blocking will be used for those small levels below which the accurate volume flow calculation is no longer possible. If the liquid level in the flume/weir falls below the blocked out range: The SmartSonic will act as follows: - Indicate No Flow on the Display. - Hold last valid data on the current output. If the level in the flume/weir is above the blocked out range: The calculation of volume flow will be based on the programmed flume/weir data; therefore the measurement values will not be influenced in any way, by the far end blocking value. FACTORY DEFAULT: Current Output P10: Value (of distance, level, volume or flow) assigned to 4 ma current output P11: Value (of distance, level, volume or flow) assigned to 20 ma current output Values are interpreted according to P01(a) and P02 (b & c). Level or Volume %: Please note that in case of programming for (LEV or VOL) % measurement, the min and max values have to be entered in the relevant engineering units of LEV (m, ft) or VOL (m 3, ft 3 ). Maximum Value: The largest number that can be entered into these parameters is Certain volume and flow applications may exceed this value. Therefore it may be necessary to convert the value to a workable unit of measure. For example, it may be necessary to convert gallons/hour to cubic feet/hour, or to convert liters to cubic meters in order to have a value of 9999 or less. This will require also making the equivalent change in P02. Inverse Proportion: Assignment can be made such that the relationship between the change of the (measured or calculated) process values and the change of the current output will be either direct or inverse. E.g., level of 1 m assigned to 4mA and level of 10 m assigned to 20 ma represents direct proportion and level of 1 m assigned to 20 ma and level of 10 m assigned to 4 ma represents the inverse proportion. FACTORY DEFAULT: P10 0 level (max distance) P11 max level (min distance) H P12: a Error indication by the current output In case of error the SmartSonic will provide one of the current outputs below. (For errors and their interpretation see Chapter 7).

24 P23: a Angle of repose (repose formation) only for free flowing solids applications This parameter provides information for the QUEST+ software for optimizing the echo-search pattern. a Estimated angle of repose 0 No angle of repose (default) 1 Below 15 (α) 2 Over 15 (α) The optimal setting of this parameter can be achieved by monitoring parameter P72. Parameter P72 indicates the echo amplitude in db. The ideal setting of P23 is that at which the parameter value in P72 becomes the best (nearest 0). 1). Set P23 for a= 1, confirm it with [E] and switch to Measurement Mode then return to Programming Mode. 2). Observe the change of echo amplitude in P72 and record an average value. 3). Perform the above with the P23 = 2 setting. 4). Finally set P23 with the value of (a) at which the amplitude value in P72 is nearest to 0. FACTORY DEFAULT: 0 P24: a Target tracking speed a Tracking speed Remark 0 Standard For most applications 1 Fast For fast changing level 2 Special Only for special applications (measuring range is reduced to 50% of the nominal value). The measuring window is inactive and the SmartSonic will respond practically instantly to any target. Recommended to fast target tracking, but usually not applicable for level metering. FACTORY DEFAULT: 0 P25: a Selection of Echo within the measuring window A so-called measuring window is formed around the echo signal. The position of this measuring window determines the flight time for calculation of the distance of the target. (The picture below can be seen on a test oscilloscope.) Received signal amplitude Echo 1. Echo 2. "t" ultrasound flight time t Some applications involve multiple (target + disturbing) echoes even within the measuring window. Basic echo selection will be done by the Quest + software automatically.

25 P26: (m/h) Level elevation rate (filling speed) Very heavy fuming P27: (m/h) Level descent rate (emptying speed) Very heavy fuming These parameters provide additional protection against echo loss in applications involving very heavy fuming. The parameters must not be smaller than the fastest possible filling/emptying rate of the actual technology. For all other applications, use the factory default setting. FACTORY DEFAULT: 2000m/h or 6562ft/h for both P26 and P27 P a Echo-loss handling a Echo-loss error indication Remark 0 Delayed During echo-loss, display and analog output will hold last value. If the echo-loss prevails for 10 sec plus the time period set in P20 (damping time), the reading on the display will change to "no Echo" and the outputs will change according to the "Error Indication Mode" preset in P12. 1 None For the time of echo-loss, display and analog output will hold last value. 2 Advance to full During echo-loss in case of filling, the reading on the display and analogue output will shift towards the "full" tank/silo state with a level elevation rate (filling speed) preset in P26 3 Immediate In case of echo-loss, the display will immediately change to no Echo and the outputs will change according to the "Error Indication Mode" preset in P12. 4 No echo-loss indication in case of empty tank/silo Echo-loss may occur in completely empty tanks with a spherical bottom due to deflection of the ultrasonic beam, or in case of silos with an open outlet. If the echo is lost when the tank/silo is completely empty, the indication will correspond to empty tank, in all other cases echo-loss indication will function according to the Delayed. FACTORY DEFAULT: 0 P29 Blocking out of object #1 P30 Blocking out of object #2 Up to two fix objects in the tank/silo that disturb the measurement can be blocked out. Enter the distance of the object from the transducer. Use the Echo Map (P70) to read out the precise distance of disturbing objects. FACTORY DEFAULT: 0 P31: Sound velocity at 20 C (m/sec or ft/sec depending on P00(c) ) Use this parameter if the sound velocity in the gases above the measured surface differs largely from that of in air. Recommended for applications where the gas is more or less homogeneous. If it is not, the accuracy of the measurement can be improved using the 32-point linearization (P48, P49). For sound velocities in various gases see section 8, Sound Velocities. FACTORY DEFAULT: Metric (P00: EU ): m/s, US (P00: US ): 1128 ft/s P32: Weight If you enter a value (other than 0 ) in this parameter, the weight will be displayed instead of VOL. In order to display weight instead of volume, enter the weight per unit volume of the process material. The units of volume, as defined by P00 and P02, must be either m 3 or ft 3. Thus the number entered must be in either kg/m 3 or lb/ft 3. The volume will be multiplied by the value entered. This parameter will not function when the units are set to read gallons or liters. FACTORY DEFAULT: 0 [kg/m 3 ] or [lb/ft 3 ] depending on P00(c) and P02(b) must be set to 0. L4660 Four-Wire Instruction Manual Page 23 of 34 Pages Rev 2, Sept 2011
