PocketPC® operating system. The SD Card plugs into the
standard SD slot found on all PocketPC®s. The WEMS
Software requires a one-time installation per PocketPC®, and
includes programs for defining, accessing, and interrogating
multiple iMonitoring devices. Chapter 3, “WEMS Software”,
includes a detailed discussion on the installation and use of
the WEMS Software.
User-supplied Components
For on-demand sensor measurements and data acquisition in the
field, the user must supply a PocketPC®, such as the one shown
at the left, to interrogate the iCCU, iWPM-T, and iTLM-1. The
PocketPC® must have a CF Card slot to accommodate the iCFR,
and an SD slot for the WEMS Software SD Card

Chapter 2
Installation
The components in Luna iMonitoring’s Intelligent Wireless Sensor Suite are easy
to install using simple tools. The installation guidelines in this manual outline the
steps for selecting the proper site for the device, and for handling, mounting and
activating the device.
Site Selection for WEMS Components
The iTLM-1 and iWPM-T sensor modules mount directly onto oil and gas tanks,
pipelines, and wellheads in the field. The iCCU mounts on a variety of structures
in and around the oil field. Issues affecting the site selected for installation
include obstructions in the line-of-sight between the sensor module and the
iCCU; distance from the sensor module to an iCCU; height of the iCCU;
proximity of the component to other electronic equipment or large metal objects
that may affect the transmission of radio signals; orientation of the solar panels
on the component; hazardous environmental conditions; and the surface
mounting angle of the tank for the iTLM-1 installation.
Guidelines Concerning RF Signal Transmission
Luna iMonitoring’s sensor modules use RF signals to communicate with iCCUs
and PocketPC®s. Following the guidelines below maximizes the range over which
the WEMS components will be able to transmit signals.
•
•
•
Place the sensor module in the direct line-of-sight with the iCCU,
whenever possible. A direct line-of-sight between the sensor
module and the iCCU provides optimal signal transmission and
reception. With a direct line-of-sight, the WEMS components
communicate up to 2500 feet. However, without a direct line-ofsight, this distance decreases.
Place the iCCU as high as possible to improve signal transmission
and reception.
Avoid placing sensor modules and iCCUs near electrical equipment
or large metal objects. Electrical devices, such as large electric
WEMS Installer’s Guide
WEMS Software
motors, power lines, antennas, and electric fences cause electromagnetic interference that adversely affect signal quality. Large
metal objects, which are electrically conductive, reflect and scatter
radio signals when placed between two RF-linked modules.
The Luna iMonitoring sensor modules, iCFR and iCCU meet FCC requirements
for CFR 47 Part 15, which dictate that operation of the device is subject to the
following two conditions:
1) The device will not cause harmful interference, and
2) The device must accept any interference received, including
interference that may cause undesired operation.
Because the device meets FCC requirements for CFR 47 Part 15, the customer
requires no operating license to transmit radio signals using the device.
To comply with current FCC RF Exposure limits, the antenna used for the Luna
iMonitoring iCCU, iEFM, iTLM-1, and iWPM-T transmitter must be installed to
provide a separation distance of at least 20 cm from all persons.
The Luna iMonitoring iCFR, iEFM, iTLM-1, and iWPM-T must not be co-located
or operating in conjunction with any other antenna or transmitter.
The Luna iMonitoring iTLM-1 sensor module utilizes ultrasonic technology and is
subject to the following additional authorization: Verification as a non-consumer
ISM device as specified by Part 18.
The Luna iMonitoring iCCU is subject to the following additional authorization:
Verification as a transmitter as specified by Part 25.
Any changes or modifications not expressly approved by the manufacturer will
void the user’s authority to operate the equipment.
Every radio-linked device in the Luna iMonitoring Intelligent Wireless Sensor
Suite carries a label. Figure 3 below shows a typical label for a sensor device
which includes the Model Number of the device, the FCC ID Number, the UL
certification, the FCC certification(s), and the Serial Number.
WEMS Installer’s Guide
WEMS Software
Figure 3. Typical Label Found on all Luna iMonitoring Radio-linked Devices.
Guidelines Concerning Solar Panels
All of Luna iMonitoring’s sensor modules and iCCUs employ a single, solarassisted battery for power. Properly orienting the solar panels on the WEMS
component achieves a maximum battery life of more than two years. Place the
component in a non-shaded area with the solar panels facing toward the sun.
Also, ensure that the site chosen will not become shaded due to tree growth or
installation of other structures.
Guidelines Concerning Hazardous Environments
Luna iMonitoring sensor modules mount directly onto structures such as a tanks,
pipelines, or wellheads located in hazardous areas. These sensor modules
(iEFM, iTLM-1, and iWPM-T) are, by design, intrinsically safe and meet the
standard for UL-913 certification for Class I, Division 1, Groups C and D
hazardous areas. By definition, an intrinsically safe apparatus is one in which all
the circuits are intrinsically safe; and an intrinsically safe circuit is one in which
any spark or thermal effect is incapable of causing ignition of a mixture of
flammable or combustible material in air under prescribed test conditions,
according to the National Electrical Code.
The iCCU mounts onto structures outside the hazardous zones in the oil field; for
example, an area greater than 3 meters from an oil tank.
Guidelines Concerning iTLM-1 Mounting
The iTLM-1 uses Ultrasonic Sensing Technology to provide tank fluid level
measurements. The sensor projects an ultrasonic beam at the surface of the
liquid in a tank. The beam reflects off the liquid’s surface back to the sensor.
The iTLM-1 acquires the raw measurement and then compensates for the effects
of temperature on the raw data. To properly measure the fluid level in the tank,
WEMS Installer’s Guide
WEMS Software
the sensor must be mounted such that the path of the ultrasonic beam is
perpendicular to the fluid surface. A mounting angle greater than 5 degrees may
cause erroneous data. Figure 4 below provides a rendering of a properly
installed iTLM-1 sensor module.
Figure 4. Proper Mounting Angle for the iTLM-1 Sensor.
Pre-installation iTLM-1 Depth Calibration
Before installing the iTLM-1 sensor device on a tank, perform the iTLM-1 depth
calibration procedure. See the section on the iTLM-1 Depth Calibration in
Chapter 3, “WEMS Software”, for details.

WEMS Installer’s Guide 15
WEMS Software
PocketConfig
The program PocketConfig includes menus for configuring and interrogating
devices. Before the PocketPC® can communicate with sensor and communication
devices, it must have certain information about the device. Therefore, the
software will not list any sensors at initial start-up of the program as in Figure 8.
Figure 8. PocketConfig Main Menu with No Defined Devices.
WEMS Installer’s Guide 16
WEMS Software
Adding New Devices
Every Luna iMonitoring device has a unique serial number found on the Luna
iMonitoring Serial Number label attached to the device. The software identifies
each device by its unique serial number. The sensor list contains the serial
numbers of the last ten devices accessed by the software. To add a device to
the sensor list, enter the unique serial number of the device in the space
provided and hit the “<” button. If the sensor list already contains ten serial
numbers as in Figure 9 below, then the least recently accessed device drops
from the sensor list. To interrogate a sensor already in the list, simply select the
proper serial number from the list and hit the “>” button to copy the serial
number into the Serial Number field. To access a sensor not in the list, type its
serial number in the space provided. The software automatically adds the serial
number to the list when the Configure button is selected. To clear the selected
sensor from the sensor list, hit the Clear button.
Figure 9. PocketConfig Main Menu.
WEMS Installer’s Guide 17
WEMS Software
Sensor Charge Modes
Sensor devices have four charge modes based on the current charge capacity of
the device’s battery. The four modes are
•
•
•
•
Always On mode, when the battery is at 100%;
Fast mode, when the battery is above 76.7% but below 100%;
Slow mode, when the battery is at or below 76.7% but above 0%;
Always Off mode, when the battery is fully discharged.
The device stays on continually in Always On mode which usually occurs on
sunny days when the solar panels can power the device and keep the battery
fully charged. In Fast mode the device “wakes up” every 10 seconds to see if it
is being interrogated. In Slow mode the device only wakes up every 2 minutes.
If the battery becomes fully discharged, then the device shuts off completely.
Setting the Default ReSync Time
The ReSync Time selected in the setup menu determines how long the software
waits for a response from a device. To access this menu, select the Setup tab
on the main menu, and hit the Options button shown in Figure 10 below.
Figure 10. Accessing the Setup Menu.
Figure 11 shows the setup menu and the ReSync Time options. If Wait for
devices in fast mode is selected, the software waits for 11 seconds to access a
WEMS Installer’s Guide 18
WEMS Software
device. Devices usually “wake up” every 10 seconds in Fast mode; therefore,
searching for 11 seconds should find the device. If Wait for devices in slow
mode is selected, the software waits for 121 seconds. The device may be in
Slow mode and will only “wake up” every 2 minutes. If Custom wait time is
selected, enter a wait time in milliseconds in the space provided. Once the
proper mode is chosen, hit the OK button to set the ReSync Time option.
Figure 11. ReSync Wait Time Selection Menu.
Finding Sleeping Devices
If a known device does not respond when interrogated, the device may be
“sleeping”, and the Resync Time may be set to only wait for devices in fast
mode. By default, the software searches for the device for the time interval
specified in the setup menu. To wake a sleeping device, enter its serial number
in the appropriate space under Find Sleeping Sensors in the main menu, and hit
the Wake button. If the software still does not find the sleeping device,
increase the search time to 121 seconds. If the software fails to find the device
after 121 seconds, check the device for possible battery failure. Using Find
Sleeping Sensors overrides the time interval selected in the setup menu. Note:
Find Sleeping Sensors wakes the device and places it temporarily in Always On
mode which significantly increases power consumption.

brackets, [ ], in the Current Device Settings window may not be changed. The
new values will appear in the Current Device Settings window.
To change Amp Mode, select an option, Low/Medium/High, from the pull-down
list. To change XmitPower, use the up/down arrows to the right of the field.
The Amp Setting and XmitPower controls are available only to reduce the power
below the authorized limits stated Appendix A of this document when desired,
the control will not allow power greater than the authorized limits. To uplink a
sensor to a specific iCCU, enter the serial number of the iCCU in the CCU field,
or enter all zeros to broadcast to all iCCUs in listening range. The Sync to PC
option synchronizes the Real Time Clock on the device to the clock on the
PocketPC®. Use this option to synchronize all devices in the field to the same
clock. Normally, Day Begin and Day End are set to 12:00 AM. To change these
parameters, use the up/down arrows to the right of the field. These parameters
only increment in 1-hour intervals.
The Current Device Settings window provides other valuable information that is
accessible using the scroll bar. Figure 15 below shows the Current Device

To access these menus, select one of the tabs along the bottom of the screen.
Some menus are similar for all devices, and some menus are device-specific. All
devices have menus for configuration, uplink scheduling, updating firmware,
setting advanced parameters, and testing the device’s radio. The iCCU has a
status menu and an uplink menu, and sensor devices have calibration menus and
a data menu.
WEMS Installer’s Guide 24
WEMS Software
Uplink Scheduling Menu
The WEMS devices run autonomously according to the uplink schedule set in the
uplink scheduling menu. Sensors uplink to an iCCU, and an iCCU uplinks to a
computer via satellite. To access this menu, select the Sched tab as shown in
Figure 16 below. The software allows for four time schedules. For each time
schedule, the software allows three pull-down options - Enabled, Disabled, or
Hourly. In the Enabled mode, the device uplinks once daily at the time specified.
In the Hourly mode, the device uplinks every hour at the minute/second
specified. Normally, Hourly mode is only used for testing purposes. To change
the time, click on the desired field, (hour, minute, second, AM/PM), and use the
up/down arrows to change the field. Once the desired schedules and times are
entered, hit Set Uplink Times to accept the changes.
Sensor devices must uplink to an iCCU at specific time intervals when the iCCU
accepts data uplinks. The iCCU is active for one minute every ten minutes
“on the tens” of every hour. In other words, the iCCU is active from
00 min. 00 sec. after the hour to 01 min. 00 sec. after the hour; from
10 min. 00 sec. after the hour to 11 min. 00 sec. after the hour; from
20 min. 00 sec. after the hour to 21 min. 00 sec. after the hour; etc. Therefore,
synchronizing the real-time clocks on all devices and properly scheduling the
uplink times on sensor devices are very important.
When setting the uplink time on a sensor device, keep in mind that, over time,
the real-time clock may drift out of synchronization by a few seconds.
Therefore, do not select an uplink time that is too close to the beginning or end
of the uplink time window. Choose a value for the seconds field that falls
between 15 and 45 seconds as in the example in Figure 16. Also, if the iCCU is
linked to several sensor devices, space the uplink times for each device about
five seconds apart to keep two devices from uplinking at the same time.

iCCU-Specific Menus
The iCCU tabs include menus for uplinking the iCCU to a computer and
displaying status information for the iCCU. Figure 19 shows the iCCU uplink
menu that is accessed by selecting the Uplink tab, and Figure 20 shows the iCCU
status menu that is accessed by selecting the Status tab.
iCCU Uplink Menu
The iCCU uplink menu, shown in Figure 19 below, uplinks the iCCU to a
computer which downloads a data set. The Uplink Mode has two options Modem, which is the default, and Direct. In Modem mode, the iCCU uplinks to a
satellite which uses the Phone # to dial up the computer. To use the Direct
mode, the iCCU must be hardware-configured to connect directly to the serial
port of a computer using a special cable.
Before beginning an uplink, verify that the current battery charge is above the
preset Uplink Threshold. To begin an uplink, choose the Uplink Mode, enter the
Phone # for the computer, and hit the Set Parameters button. Once the
software accepts the parameters, hit the Uplink NOW! button to send the most
recent data points for each device uplinked to the iCCU.

iCCU Status Menu
The iCCU status menu, shown in Figure 20 below, provides additional
information about the current status of the iCCU indicated by the serial number
in the CCU Status window. To get the current status, select the Status tab and
hit the Get Status button. The Charge field indicates the current charge of the
battery. Fast Mode Level is the battery charge level below which the device
switches from Fast Mode to Slow Mode, and the Always Off Level is the level
where the device shuts itself off.
Under Uplink Status, Last Uplink indicates the time of the most recent uplink to
the satellite, and Next Uplink indicates the scheduled time for the next uplink. A
Status code of 0x00 indicates that the last uplink was successful.

iTLM-1 Depth Calibration
The iTLM-1 depth calibration must be performed during the process of
installing the iTLM-1 sensor device on the tank.
At the time of the device installation, the iTLM-1 needs to know the exact depth
of the fluid in the tank to perform the depth calibration for the tank level sensor.
To set the depth calibration parameter, select the Depth Cal tab at the bottom of
the screen to access the depth calibration menu shown in Figure 26 below.
Enter the current depth of the fluid in the tank in inches in the Measured Depth
field, install the iTLM-1 sensor, and hit the Set Depth Cal button. Once the
depth calibration is complete, the value “-2” appears in the Measured Depth field
to block any inadvertent changes to the calibration parameters. Luna
iMonitoring personnel use the “-1” value, which removes the depth calibration
and reports distance. This is useful when performing the distance calibration.

Using the Charge Cable
Figure 38. WEMS Charge Cable.
Luna iMonitoring provides a device Charge Cable, shown in Figure 38 above,
with most Beta Test versions of the Wireless Enabled Monitoring System. The
Charge Cable is for use in a lab setting and is not tested or approved
for use in hazardous environments. The Charge Cable has an SMA
connector at one end and a USB connector at the other end. The SMA connector
plugs into the SMA antenna connector on the WEMS device being tested. The
antenna on each WEMS device simply screws off of the SMA connector. The USB
connector plugs into the USB port of any computer. The SMA connector serves
as an antenna connection as well as a power connection. Therefore, the device
receives power from the USB port on the computer when the computer is on.
Even though the antenna is disconnected, the device can still receive and
transmit radio signals in a lab setting.
The Charge Cable serves two purposes:
1) It quickly charges the battery to full capacity.
2) It maintains a full charge on the battery in a lab setting where the
solar panels can not charge the battery.
