• Installation Notes
Mount your LOE sensor so that it has a clear, perpendicular sound path to the surface being moni­tored. Your sensor should be mounted away from tank or vessel walls and inlets. (See Figure 2.1)
The sound path should be free from obstructions and as open as possible for the 9° o axis beam
pattern.
If you are using a stand pipe, please see our guide to stand pipes on our website:
http://www.apgsensors.com/about-us/blog/how-to-install-a-stand-pipe.
Figure 2.1
Mounting Instructions
Mounting your LOE is easy if you follow a few simple steps:
Never over-tighten the sensor.
Always screw in your sensor by hand to avoid cross-threading. Thread failure can be a problem if you
damage threads by over-tightening them or by crossing threads.
IMPORTANT: Do not over tighten! The sensor should be threaded in only hand tight.
NOTE: Do not mount the sensor where the beam will intersect objects such as ll
streams, pipes, ladder rungs, wall seams, or corrugated tank walls.

• Software Setup
Initial setup of the LOE and individual Modbus sensors is done via an embedded web server. The embedded server can be accessed by using either the serial number or local IP address of the LOE and a web browser
(Internet Explorer, Chrome, Firefox, etc).
NOTE: Port 6700 must be open on your local network for the LOE to connect.
Accessing LOE Embedded Web Server via Serial Number
The easier way to access the embedded web server is to type loe_xxx into a web browser on a computer connected to the same local network as the LOE. xxx represents the numeric portion of the LOE’s serial number. See Figures 2.2 and 2.3.
Figure 2.2
Figure 2.3
NOTE: If your web browser performs a web search for “loe_xxx” istead of accessing the
server, type “http://loe_xxx”.
Some networks will block this direct access to the LOE. If this is the case, you will need to use the IP address of your LOE to access the embedded web server. The IP address can be obtained two ways: ask your local network administrator, or logon to your APG-provided website, www.levelandow.com.

Chapter 3: Programming with Modbus TCP/IP
Modbus Polling via Ethernet with Modbus TCP/IP
Using the LOE’s IP address, and port number 502, readings can be polled from the LOE for any attached sensors via RS-485 Modbus commands. Up to 14 16-bit Input Registers, beginning with register 299, can be polled with a single command. Below is a sample Modbus command illustrating the necessary syntax.
Example:
00 01 : Transaction Identier 00 00 : Protocol Identier 00 06 : Message Length (6 bytes to follow) 0B : The Reporting Unit Identier [sensor number] (0B hex = 11) 04 : The Function Code (04 = read Input Registers) 01 2E : The Data Address of the rst register requested. (12E hex + 1 = 303) 00 02 : The total number of registers requested. (read 2 registers, i.e. 303 to 304)
Byte order (hex values) 00 01 00 00 00 06 0B 04 01 2E 00 02
Notes:
Reporting Unit indicates the sensor reading being polled from the LOE, in hex. 01 - 0A are for Modbus sensors 1 - 10 attached to the LOE. 0B (i.e. sensor 11) reads the values from the LOE sensor (See Figure
2.8). Unused registers (i.e., those not associated to an attached sensor) will return zeros when polled.
Function Code 04 reads the Input Registers. No other functionality (e.g., polling from or writing to Hold­ing Registers) is supported via Modbus TCP/IP with the LOE. Complete control functionality is available through the embedded web server and through your APG-provided website (www.levelandow.com).

PARAMETER RANGE
Sensitivity 0 - 100%
Sensitivity sets the level of gain that is applied to the echo. When operating in AutoSense, Hard-Target, or
Soft-Target (see Gain Control), Sensitivity sets an upper limit for the amplication that can be applied to the echo. If operating in Manual, this parameter sets the gain.
When using manual gain control, set Sensitivity to the minimum value that will allow the target to be reliably tracked through the full range of expected environmental conditions.
IMPORTANT: Parameter values stored on the LOE will not update until the “Change”
button is clicked or the Enter key is pressed.
PARAMETER RANGE
Blanking Determined by sensor model
Blanking sets the blanking distance, which is the zone from the Zero Point of the sensor to the point from
which the rst echo will be accepted. While blanking distance can be used to ignore unwanted targets--such as welds, seams, pipe ttings, or gaskets--between the sensor and the closest acceptable target level, such objects generally create additional reections and echoes, which are hard to lter out. More often, blanking
distance is used for a sensor installed in a stand pipe.
Because of the physical properties of an ultrasonic sensor, objects cannot be detected closer than approximately 1 foot from the face of most transducers (5 inches for LOE-7126, 7 inches for LOE-6126). However, this distance varies according to how much energy is being transmitted (Pulses) and the
installation.
IMPORTANT: Blanking is always measured from the Zero Point of the sensor. See Fig-
ures 4.5 - 4.7.

PARAMETER RANGE
Pulses 0-20
Pulses sets the maximum number of pulses the sensor can transmit when operating in AutoSense, Hard-
Target, or Soft-Target (see Gain Control), or sets the number of pulses when operating in Manual. The more pulses that are sent in a burst, the stronger the returning echo.
When operating in Manual, increase the strength of the transmission by increasing Pulses for detecting soft targets in damping environments. In acoustically active environments or small enclosed areas, decrease
Pulses to reduce multiple echoes.
PARAMETER RANGE
Gain Control 0 = Manual
1 = AutoSense 2 = Hard-Target 3 = Soft-Target 4 = Auto-Soft Target 5 = Auto-Hard Target
Gain Control selects the control mode for the LOE sensor’s gain settings (Sensitivity and Pulses). In AutoSense, the sensor automatically adjusts the sensitivity and pulses for the best quality return signal. Manual, Hard Target, and Soft Target are user controlled scenarios. In Manual, the user is in full control of Sensitivity and Pulses. For Hard and Soft Target, the user sets maximum Sensitivity and Pulses, but the overall gain is either ramped up slowly (Hard Target) or quickly (Soft Target) by the sensor.
PARAMETER RANGE
Average 1-32
Average sets the number of qualied samples to average for the displayed reading. Qualied samples are
placed in a rst-in, rst-out buer, the contents of which are averaged for Distance. The larger the number of qualied samples being averaged, the smoother the Distance reading will be, and the slower the reading will be to react to quick changes.

PARAMETER RANGE
Window 0 - Sensor Maximum
Window determines the corresponding physical range for qualied samples, based on the current Distance.
Samples beyond the +/- Window range of the current Distance will not qualify unless the average moves. Samples outside the extents of the Window are written to the Out of Range Samples buer. (See Figure 4.8.)

PARAMETER RANGE
Out of Range Samples 0-250
Out of Range Samples sets the number of consecutive samples outside the Window necessary to automatically adjust the current Distance and move the Window.
PARAMETER RANGE
Sample Rate 1 - 20 Hz
Sample Rate is the number of sample readings taken by the LOE every second.
PARAMETER RANGE
Multiplier 0 - 1.999
Multiplier is used to calibrate the LOE sensor for variations in the speed of sound due to variations in
atmospheres. The default of 1.000 is used for most applications.
PARAMETER RANGE
Temp Comp. 0 = O 1 = On
Temperature Compensation activates or deactivates the LOE’s internal temperature compensation circuit.
The speed of sound changes with changes in temperature, therefore changes in temperature can aect distance measurements. These eects can be minimized by activating temperature compensation.

PARAMETER RANGE
Oset -10 ft - + 10ft
Oset is used to change the Zero Point of the LOE sensor. The Zero Point of the sensor is the point from
which the calculated distance is measured. When the Oset is set to 0, the Zero Point of the sensor is at the face of the transducer (See Figure 4.5). A positive setting will move the Zero Point forward, in front of the sensor face (See Figure 4.6). Setting the Oset to a negative number will move the Zero Point backward, behind the sensor face (See Figure 4.7).
In all cases, Blanking is measured from the end of Oset, and the eective measurement zone of the sensor begins at the forward end of Blanking. If Oset is more negative than Blanking is positive, the net dierence will be a loss in sensor maximum range (See Figure 4.7).
PARAMETER RANGE
Max Distance Determined by sensor model
Maximum Distance sets the maximum acceptable signal range (up to the physical maximum of the sensor), measured from the Zero Point. Signals beyond the Maximum Distance are ignored. Under Loss of Echo conditions, the Distance reading will display the Maximum Distance.

Chapter 5: Maintenance
General Care
Your LOE series controller is very low maintenance and will need little care as long as it is installed correctly.
However, in general, you should:
Avoid applications for which the sensor was not designed, such as extreme temperatures, contact with incompatible corrosive chemicals and fumes, or other damaging environments.
Inspect the threads whenever you remove the sensor from duty or change its location.
Troubleshooting
Should you have problems with your LOE Ultrasonic Sensor, here are some troubleshooting steps.
Check the received signal strength (See Figure 4.9). If the signal strength is low, alternately increase Pulses and Sensitivity (See Figure 4.4) until the signal strength improves.
Ensure Temperature Compensation (See Figure 4.4) is On (set to 1).
Set the Gain Control to AutoSense (See Figure 4.4).
Ensure that Blanking (See Figure 4.4) is accurately set to account for any unwanted targets between the
sensor and the closest acceptable target (See Figures 4.5 - 4.7).
Should you have problems with your LOE Modbus Network Controller, here are some troubleshooting
steps.
Check the Modbus Network connections at the LOE and at each of the attached sensors.
Ensure that each attached sensor has been assigned a unique Sensor Number (Figure 4.23; Assigning
Modbus Sensor Numbers, page 12).
Check the Holding Register Settings for each attahed sensor (Figures 4.17 and 4.18).

• Calibration
This procedure uses targets at known distances to calibrate the LOE sensor’s accuracy. A wall or other large, at object is recommended for the long range target.
Point the sensor at a target at a known distance near the maximum range of the sensor (See Figure
5.1).
Adjust the Multiplier value until the distance reading on the sensor matches the actual measured dis­tance to the target (See Figure 4.4).
Point the sensor at a target near the minimum measurement range, 1’ plus any Blanking distance (See Figure 5.2).
Adjust the Oset value until the distance reading on the sensor matches the actual measured distance to the target (See Figure 4.4).
Repeat previous two steps until no further adjustment is required.
