• 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
fi 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.

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.

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 off
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 Iden fi er
0000: Protocol Iden fi er
0006: Message Length (6 bytes to follow)
0B: The Unit Iden fi 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)

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.

Website Alarms

There are three diff erent types of website alarms: Immediate, Interval, and
Heartbeat. Refer to descrip ons below.

Immediate Alarms: results from an alarm condi on on one of the LOE’s solid
state relays (Trip 1 & Trip 2). If one of the trip relays enters an alarm condi on,
the LOE will report the alarm to the website without wai ng for the next
scheduled call-in interval.

NOTE: in addi on to se ng an alarm on the website, the LOE’s trip relays
must also be confi gured for website alarming. See “Confi guring the LOE for
Website Alarms” on page X for details.

Rev. B, 1/12 LOE Series

Interval Alarms: alarm condi on is based solely on the sensor readings as
reported at the scheduled call-in interval. i.e. the alarm is a func on of the
website and is not generated by the sensor itself.

Heartbeat Alarm: once every 4 hours the website checks the call-in status of all
sensors that have been assigned a heartbeat alarm. If the LOE missed the last
scheduled login, an alert message would then be sent to no fy the user(s) that
the sensor is not reported to the website.
