LOE Series Rev. B, 1/12
• Understanding Ultrasonics
Ultrasonic sensors use a transducer to transmit bursts of ultrasonic sound waves. Each burst contains a series of pulsed sound waves that emit in the shape of a cone, refl ect off the target, and are detected by the sensor. The  me required for the sound waves to travel to and from the target is converted into a distance measurement by the sensor. Ultrasonic sensing is aff ected by several factors including the target surface, distance, size, and angle. The following considera ons will help ensure the best possible target condi ons.
Surface
The ideal target surface is hard and smooth. This type of surface will refl ect a greater amount of signal than a so or uneven surface. Sound wave absorbent materials, such as granules and powders, will reduce the opera ng range of the sensor and decrease measurement accuracy.
Distance
Sound wave a enua on increases as the distance traveled increases. Therefore, targets at longer ranges require be er refl ec ve characteris cs than targets that are closer to the sensor.
Size
A large object will have a greater surface area to refl ect the signal than a smaller one. Therefore, a large target will be detected at a greater distance than a small target. The surface area recognized as the target will generally be the por on closest to the sensor.

Rev. B, 1/12 LOE Series
Angle
The inclina on of the object’s surface in rela on to the sensor face will aff ect the strength of the refl ected sound waves. Surfaces perpendicular to the sensor will refl ect more signal directly back to the sensor. If a surface is more than a few degrees off perpendicular, enough of the signal will be refl ected away from the sensor that the target will not be detected. Generally speaking, a target angle greater than 5 degrees off perpendicular will not be detected. The target angle becomes increasingly cri cal as the distance to the target increases.
Environmental Condi ons
Temperature, humidity, vapors, dust, and pressure can aff ect the sensor’s performance. APG ultrasonic sensors are designed to compensate for many of these condi ons. However, if the condi ons are extreme, sensor performance can be degraded enough to require the use of a longer-range sensor than normal condi ons would require. Ultrasonic sensors may not be suitable for applica ons with heavy chemical vapors (such as solvents or gasoline), heavy dust or when signifi cant surface foam is present.

LOE Series Rev. B, 1/12
DO NOT mount the sensor where the beam will intersect objects such as fill streams, pipes, ladder rungs, wall seams, or corrugated tank walls.
Installa on
The LOE must be mounted in a loca on with an unobstructed column of air to the target. The beam-spread chart on the previous page can be used as a rough guide to determine the required diameter of the air column for ranges of 10 feet or less. A 3 to 4 foot diameter air column is typically suffi cient even at the maximum range of the sensor.
The sensor should be mounted to ensure the target does not come closer than the minimum sensing range (blanking distance).
The sensor should be mounted so that the sensor face is perpendicular to the target surface. Even just a few degrees off -perpendicular can cause a loss of echo condi on. Proper alignment becomes increasingly important as the range to the target increases.
Stand Pipe Moun ng
When using a stand pipe to raise the sensor above a tank, use a single seamless piece of pipe to provide the sound waves a smooth path to propagate into the tank. Because the sound waves becomes concentrated along the pipe walls, even small sharp edges, such as seams or burs, can cause errant readings.

Sensor Setup via DHCP (automa c IP confi gura on)
Connect the LOE to a network that provides access to the internet, and apply power to the sensor. The COM LED should begin to fl ash once every 30 seconds, indica ng the DHCP is a emp ng to establish communica on with the web site. Once communica on is established, the COM LED will illuminated.
NOTE: see Troubleshoo ng DHCP if COM LED con nues to fl ash from more than 2-3 minutes.
Accessing the Internal Web Pages
To access the sensor’s se ngs, open an Internet browser, and in the address bar enter: loe_# where # is the sensor’s serial number beginning at the rst whole number. For example if the serial number is L000001275, then you would enter loe_1275 into the browser address bar. The following screen should appear:
NOTE: if typing the loe_# does not work, it may indicate the DHCP has saved a previous name for the IP assigned. Power down the sensor and have the System Administrator delete this name from the DHCP server.
Next, click the “Home” bu on and use the following default login when prompted: Username: admin Password: password
NOTE: use the Security link on the main page to set the desired Username and Password.

LOE Series Rev. B, 1/12
Basic Parameters (con nued)
Sensi vity
Controls the level of amplifi ca on applied to the target signal. The sensi vity se ng is expressed as a percentage; 0 to 100%. When opera ng in Autosense mode, the Sensi vity se ng acts as an upper limit constraint (see Gain Control for details).
Blanking
Sets the distance, beginning at the sensor face, to the point where the sensor will begin looking for target signals. All targets closer than the blanking distance will be ignored. The blanking should never be set to less than the minimum range specifi ca on of the sensor. If the target enters the blanking area, errant readings will occur.
NOTE: the LOE-6126 has the ability to track a target to as close as 1” from the sensor face. This feature is limited to targets that will remain perfectly perpendicular to the sensor face. Control to 1 (Autosense) and then se ng the Blanking to 0.
This feature is enabled by se ng the Gain
Pulses
Controls the number of sound wave pulses being sent in each ultrasonic burst. The greater the number of pulses, the stronger the transmi ed signal. When opera ng in Autosense mode, the Pulses se ng acts as an upper limit constraint (see Gain Control for details).
Gain Control (0, 1, 2, 3)
Determines the method in which gain is applied to returning target signals. In Manual mode, the Sensi vity and Pules se ngs are applied as a sta c values. In Autosense Mode, the sensor self-adjusts the Pulses and Sensi vity levels (within the bounds of their respec ve se ngs) in order to op mize the signal strength.
0 = Manual Mode (sta c Sensi vity & Pulses values) 1 = Autosense (auto-adjus ng Sensi vity & Pulses values) 2 = Hard-Target (increases gain slowly as distance increases) 3 = So -Target (increases gain quickly as distance increase)

Rev. B, 1/12 LOE Series
Basic Parameters (con nued)
Averaging
Defi nes the number of target readings that will be averaged together. Each qualifi ed sample (see Filter Window and Out of Range Samples below) is placed into a fi rst-in, fi rst-out (FIFO) buff er and averaged with previous samples to gen- erate a steady output. A higher Averaging se ng will result in smoother read- ings, but will also result in slower the response  me to rapid target changes.
Window
Sets the width of the target acceptance window. The target acceptance window is a zone, centered around the current target reading, within which any target detected will be considered legi mate and fi gured into the averaging buff er. Any target detected outside of the Window will be considered “out of range” and will be ignored based on the se ng in the Out of Range Samples parameter (see below). The Filter Window extends both direc ons, both closer than and further away from, the current target reading. For example, if the sensor is detec ng a target at 5  . and the Filter Window is set at 1  ., then any target detected between 4  . and 6  . will be accepted.
Out of Range Samples
Determines the number of consecu ve target readings that must fall outside of the acceptance window before the “out of range” target is recognized and included in the averaging buff er. For example, suppose the Out Of Range Samples is set to 10. If a target is suddenly detected outside of the acceptance window, it will be ignored un l it has been detected for 10 consecu ve samples, at which point it will be qualifi ed as a legi mate target. If the “out of range” target was detected for only 9 consecu ve samples before moving out of the sensing area, it would never be acknowledged as a target and the reading would stay with the last qualifi ed target sample.
Sample Rate
Sets the interval between target readings. Op ons allow rates from once per second (1 Hz) to 5  mes per second (5 Hz). It is highly recommended that the Sample Rate be set only as fast as is necessary for the applica on.

LOE Series Rev. B, 1/12
Basic Parameters (con nued)
Mul plier
Sets the conversion Mul plier that will be applied to the sensor readings. The default is 1.000 (see note below) and typically does not need to be adjusted. However, since the speed of sound is not constant through all environments, the mul plier parameter allows the user to adjust for varia ons in atmosphere when maximum accuracy is required.
Temperature Compensa on (0 = Off , 1 = On)
Used to enable or disable the internal temperature compensa on of the sen- sor. Enabling the internal temperature compensa on can reduce the eff ects of temperature changes by 50% or more, depending on the temperature gradient through the sensing range.
Off set
Used to adjust the zero reference point of the sensor. When the Off set is set to 0, the zero reference of the sensor is at the face of the transducer. Se ng the Off set to a nega ve number will move the zero reference backward (behind the sensor face), while a posi ve se ng will move the reference forward (in front of the sensor face).
Maximum Distance
Sets the distance (beginning from the sensor face) to the point where the sen­sor will stop looking for target signals. Targets detected beyond the Maximum Distance value will be ignored by the sensor.

Rev. B, 1/12 LOE Series
Trip Point Relay Control
The standard version of the LOE comes equipped with two solid-state relay outputs (trip points), which can be programmed to perform one of several logic func ons. In addi on, the LOE can be confi gured to ini ate immediate email and/or text message alerts whenever either of the trip relays ac vates or deac vates (see Immediate Website Alarms for more informa on).
NOTE: all Trip Point distance values are referenced from the face of the sensor, regardless of the type of calculated reading being performed by the sensor (level, volume, etc.). Refer to Trip Type chart for more informa on.
Trip Distance: sets the distance from the sensor face to the closest ac on point (refer to Trip Type chart).
Trip Window: sets the distance, beginning from the Trip Distance loca on, to the farthest ac on point (refer to Trip Type chart).
Trip Type: determines the type of opera onal logic performed by the trip point relay (see descrip ons below and refer to the Trip Type chart).
Type 0 (Near): ac vates the relay when a target is closer than the Trip Distance. The Trip Window is not used with Trip Type 0.
Type 1 (Exclusive): ac vates the relay when a target is closer than the Trip Distance or farther than the Trip Distance + the Trip Window.
Type 2 (Hysteresis Near): When the target comes closer than the Trip Distance, the relay will ac vate and remain on un l the target moves beyond the Trip Distance + Trip Window. The relay will then deac vate and remain off un l the target once again comes closer than the Trip Distance. Used for emptying control or high alarm with hysteresis to prevent cha er.
Type 3 (Far): ac vates the relay when the target is beyond the Trip Distance. The Trip Window is not used with Trip Type 3.

Trip Point Relay Control (con nued)
Type 4 (Inclusive): ac vates when the target is within the trip window. This
can be used for various presence detec on applica on.
Type 5 (Hysteresis Far): When the target moves beyond the Trip Distance + Trip Window, the relay will ac vate and remain on un l the target moves closer than the Trip Distance. The relay will then deac vate and remain o un l the target once again moves beyond the Trip Distance + Trip Window. Used for fi lling control or low alarm with hysteresis to prevent cha er.
Type 6: Disables the trip point relay.
Type 7 (Loss of Echo): the relay will ac vate if the sensor enters a loss of
echo condi on (no targets detected).
Type 8 (Timed Relay): sets the relay to ac vate at a specifi ed interval. The Trip Distance parameter sets the  me interval between relay ac va ons (in minutes), and the Trip Window determine how long the relay remains ac ve at each interval (in seconds).
Type 9 (Rate of Change): allows the user to defi ne a maximum rate of change (distance over  me), which if exceeded will ac vate the relay. The Trip Distance parameter is used to defi ne the  me value, and the Trip Window parameter is used to defi ne the distance value.
Retry Time
Sets the delay between a empts to connect to the Website a er a failed connec on. The Retry Time is also used to set the delay before repor ng trip alarms to the website. Refer to Alarm Filter .

Website Alarms: the LOE’s trip relay outputs can be confi gured to report to the levelandfl ow.com website whenever an alarm condi on is detected, regardless of the sensors fi xed call-in interval. An Immediate alarm can then be setup on the website to ini ate email and/or text message alerts whenever an alarm is reported (see using the levelandfl ow website for more informa on).
NOTE: Immediate website alarms are subject to the Retry Time delay (30 to 180 second) as set in the LOE’s Basic Parameters page. Addi onal delays may occur in establishing a connec on to the website, depending on the speed and quality of the local internet connec on.
Confi guring the LOE for Website Alarms:
Placing a “1” in front of any of the Trip Types designates a closed or ac ve output as an alarm condi on. For example; Trip Type 3 would be designated as 13, and would send out an immediate alarm whenever the trip relay is ac ve (closed).
Placing a “2” in front of any of the Trip Types designates an open or inac ve output as an alarm condi on. For Example; Trip Type 3 would be designated as 23, and would immediately report an alarm whenever the trip relay is inac ve (open).
Alarm Filter: (located in the LOE’s Network Se ngs page) enabling the Alarm Filtering op on can help prevent nuisance email and/or text message alerts from being sent. If Alarm Filtering is enabled, all alarms condi ons that clear before the Retry Time delay expires will not be reported to the website, and no alert messages will be sent. If Alarm Filtering is disabled, all trip alarms will be reported to the website (and alert messages sent), even if the alarm condi on has cleared when the Retry Time expires.

Rev. B, 1/12 LOE Series
Modbus
The LOE has the capability to interface with up to 10 of APG’s Modbus based sensors. The LOE acts as the Master device, querying the Modbus sensors and repor ng their readings to the website along with the LOE’s own readings.
NOTE: each Modbus sensor will show up on the website as a sub-sensor to it’s LOE master. For example, if the LOE’s serial number is L00001219, then Modbus sensor 1 would be displayed as L00001219_1 and so forth.
RS-485 Modbus Input 1 & 2
These pages are used to confi gure the parameters of Modbus sensor currently selected (see “Sensor Number to View” under “RS_485 Network Se ngs” page). Not all parameters are applicable to every Modbus sensor. Refer to the Modbus sensor’s user manual for parameter descrip ons.
RS-485 Modbus Holding Registers
This page is available to view the readings of the Modbus sensor that is cur­rently selected.
Modbus TCP/IP
Using the LOE’s IP address and port number 502, the LOE’s readings can be polled at address number 11 on registers 30303-30304.
Example:
0001: Transac on Idenfi er 0000: Protocol Idenfi er 0006: Message Length (6 bytes to follow) 0B: The Unit Idenfi er (0B hex = 11) 04: The Func on Code (read Holding Registers) 012E: The Data Address of the fi rst register requested. (12E hex = 303) 0002: The total number of registers requested. (read 2 registers; 303 to 304)
Byte order (hex values) 00 01 00 00 00 06 0B 04 01 2E 00 02

RS-485 Se ngs
Baud Se ngs: selects the communica on baud rate between the LOE and the
a ached Modbus sensors. Refer to the Modbus sensor’s documenta on for the appropriate se ng (typically 9600 Baud).
Number of Sensors On Line: sets the number of Modbus sensors that are con­nected to the LOE.
Sensor Number to View: used to select the sensor number to be viewed or programmed (also see “New Sensor Number” below). The parameters of the selected sensor will populate the RS-485 Modbus Input pages, and the sensor’s readings can be viewed in the RS-485 Holding Register page.
New Sensor Number: used to change the sensor number of the sensor cur­rently being viewed (see “Sensor Number to View” above). Each Modbus sen­sor connected to the LOE must be assigned a unique sensor number (0 to 10). Duplicate sensor numbers will cause errors in communica on.
Delay Between Call-in Times: sets the delay between cycles of querying all at­tached Modbus sensors.
