What is the LevelSCOUT?
The Seametrics LevelSCOUT Smart Sensor is an integrated datalogger and level/temperature
sensor and is ideal for site assessments, tidal studies, environmental monitoring, surface
water discharge measurement, and aquifer level monitoring, as well as aquifer storage and
recovery. This sensor networks with all of the Seametrics Smart Sensor family.
This industry standard digital RS485 interface device records up to 50,000 records of level,
temperature, and time data, operates with low power, and features easy-to-use software
with powerful features. Constructed with 316 stainless steel, acetal, and Viton®, this sensor
provides high-accuracy readings in rugged and corrosive eld conditions.
The LevelSCOUT is an absolute sensor, requiring no vent tubes, desiccant, or bellows. It can
be paired with a BaroSCOUT barometric sensor and used with the Aqua4Plus 2.0 Barometric
Compensation Utility to adjust the LevelSCOUT readings for current atmospheric pressure.
A 1/2 AA 3.6v lithium battery powers the LevelSCOUT. The unit is programmed using
Seametrics’ easy-to-use Aqua4Plus 2.0 control software. Once programmed the unit will
measure and collect data at the time interval programmed.
Replace your analog sensor/datalogger with the Seametrics LevelSCOUT as a stand-
alone unit or network with other Seametrics Smart Sensors. While most will use the
LevelSCOUT with Seametrics Aqua4Plus 2.0 software, it is by no means limited to
that software. You can use your own Modbus® RTU software or logging equipment
to read measurements via RS485, tying into your existing systems and data bases.
Initial Inspection and Handling
Upon receipt of your smart sensor, inspect the shipping package for damage. If any
damage is apparent, note the signs of damage on the appropriate shipping form. After
opening the carton, look for concealed damage, such as a cut cable. If concealed damage
is found, immediately le a claim with the carrier.
Check the etched label on the sensor to be sure that the proper range and type were
provided. Also check the label attached to the cable at the connector end for the proper
cable length.

Seametrics • 253.872.0284 Page 5 seametrics.com
How Pressure/Level Sensors Work
Liquids and gasses do not retain a xed shape. Both have the ability to ow and are often
referred to as uids. One fundamental law for a uid is that the uid exerts an equal
pressure in all directions at a given level. Further, this pressure increases with an increasing
depth of “submergence”. If the density of a uid remains constant (noncompressible...a
generally good assumption for water at “normal” pressures and temperatures), this
pressure increases linearly with the depth of “submergence”.
We are all “submerged” in the atmosphere. As we increase our elevation, the pressure
exerted on our bodies decreases as there is less of this uid above us. It should be noted
that atmospheric pressure at a given level does vary with changes in the weather. One
standard atmosphere (pressure at sea level at 20º C) is dened to be 14.7 PSI (pounds per
square inch).
There are several methods to reference a pressure measurement. Absolute pressure is
measured with respect to an ideal vacuum (no pressure). Gauge pressure is the most
common way we express pressure in every day life and is the pressure exerted over and
above atmospheric pressure. With this in mind, gauge pressure (Pg) can be expressed
as the dierence between the absolute pressure (Pa) and atmospheric pressure (Patm):
Pg = Pa - Patm.
The LevelSCOUT is an absolute sensor and will require an outside barometric reference
to obtain “gauge” type readings.
GENERAL INFORMATION
Do handle the device with care.
Do store the device in a dry, inside
area when not in use.
Do install the device so that the
cable connector is kept dry.
Don’t support the device with the connector.
Use a strain relief device to take the
tension o the connectors.
Don’t allow the device to free-fall down a well
as impact damage can occur.
Don’t bang or drop the device on hard
objects.

General Specication
The Seametrics LevelSCOUT is a microprocessor based digital intelligent sensor designed
to measure and record level, temperature, and time, utilizing state-of-the-art low power,
battery operated circuitry.
Level is measured with an extremely rugged and stable piezo-electric media-isolated
pressure element combined with an analog-to-digital converter. This provides extremely
accurate and stable pressure input into the microprocessor on the circuit board.
Temperature is measured with an epoxy bead thermistor. The data is stored in non-
volatile memory. A serial communication link (RS485) provides communication to the
host computer.

Power
The LevelSCOUT comes with a 1/2 AA 3.6v lithium battery.
Connecting the LevelSCOUT to a Computer
In its cabled conguration, the sensor cable is terminated with a weather-resistant
connector. In its cableless conguration, the sensor is terminated with a weather-
resistant connector inside a screw-cap. Connect the weather-resistant connector to
your computer’s USB port as shown below.
Connect the sensor to your PC using Seametrics’ USB to RS485
adapter.
Installing the Aqua4Plus 2.0 Software
The LevelSCOUT comes with the Aqua4Plus 2.0 host software that is installed on your PC
or laptop. Use this software to program the datalogger, to retrieve data from the logger,
to view collected data, and to export data to external les for use with spreadsheets or
databases.
Refer to the Aqua4Plus 2.0 software manual for details on installing and using the software.
LevelSCOUT can also be used with the full Aqua4Plus 2.0 software.
Using the LevelSCOUT Without Aqua4Plus 2.0

Seametrics • 253.872.0284 Page 9 seametrics.com
Installing the Sensor
The LevelSCOUT measures level. The most common application is measuring liquid levels
in wells and tanks. In order to do this, the sensor must be installed below the water
level at a xed depth. The installation depth depends on the range of the sensor. The
sensor should not be installed below its maximum depth. If the sensor is installed below
its maximum depth, damage may result to the sensor and the output reading will not be
correct.
Note: If you are using an absolute sensor and you want to enter a depth-to-water
reference after data is collected, then see Appendix E before proceeding.
• Lower the sensor to the desired depth.
• Fasten the cable to the well head using tie wraps or a weather proof strain-relief
system.
• Take a measurement to insure the sensor is not installed below its maximum range.
Be sure the supplied cap is securely placed on the weather-resistant connector at the
top of the cable. Do not install such that the connector might become submerged with
changing weather conditions. The connector can withstand incidental splashing but is not
designed to be submerged.
The sensor can be installed in any position; however, when it leaves the factory it is
tested in the vertical position. Strapping the sensor body with tie wraps or tape will
not hurt it. If the sensor is being installed in a uid environment other than water,
be sure to check the compatibility of the uid with the wetted parts of the sensor.
Battery Life Calculator
The LevelSCOUT has a battery life calculator that is set at the factory when batteries are
rst put in the sensor. If you need to replace the batteries, see the Maintenance section
for replacement information and for information on resetting the battery life calculator.
If the battery life calculator is not reset, the remaining life information will be
incorrect.

While the LevelSCOUT comes with Seametrics’s easy to use Aqua4Plus 2.0 software, you
can also use standard Modbus® RTU equipment to easily take readings, so as to tie into
your existing equipment or networks.
Setting Units for Direct Read
By default, the LevelSCOUT uses the following units:
Temperature Degrees Celsius
Level PSI
However, you can select from a variety of units for direct read measurements. If you want
to change to dierent units, for example, degrees Fahrenheit for temperature or feet of
water for level, set these units using Aqua4Plus 2.0 (see sensor settings).
Once set, these units are saved on the sensor and direct readings will return values using
these units. (Note: These settings do not aect the units used on the Aqua4Plus 2.0 display.
Refer to the software manual for details.)
DIRECT READ MODBUS/SDI-12
LEVELSCOUT INSTR
Seametrics • 253.872.0284 Page 31 seametrics.com
Reading Via Modbus® RTU
Taking Measurements
Read measurements using Modbus function 03 – Read Holding Registers.
Readings are located in two registers each, starting at address 62592. (LevelSCOUT register
addressing is zero based, i.e., starts at zero. If your equipment uses one based addressing,
you will need to add one to the register addresses.)
Measurement Timing
When you request a reading via Modbus, the sensor wakes up, returns the current values
in the registers, and then starts taking new readings and updating the registers. After
approximately four seconds, if no more readings have been requested, the sensor goes
back to sleep.
Because of this, the rst reading you get will be old. If you are taking readings at intervals
of less than four seconds, simply ignore the rst reading — all remaining readings will
be current. On the other hand, if you are taking readings at intervals of greater than four
seconds, take a reading, ignore it, wait one second, take another reading. Record this
second reading.
Data Format
The data is returned as 32-bit IEEE oating-point values, highword rst, also referred to as
big-endian or oat inverse.

Changing Batteries
The LevelSCOUT is powered by a single 1/2 AA 3.6 lithium battery. In most situations
the battery will last for years. If you need to replace the battery, contact Seametrics for
information on getting it replaced. You cannot simply replace the battery itself but must
replace the entire compartment.
Miscellaneous
Sensor: There are no user-serviceable parts, other than the batteries. If problems develop
with sensor stability or accuracy, contact Seametrics. If the sensor has been exposed to
hazardous materials, do not return it without notication and authorization.
Cable: Cable can be damaged by abrasion, sharp objects, twisting, crimping, crushing,
or pulling. Take care during installation and use to avoid cable damage. If a section of
cable is damaged, it is recommended that you send your sensor back to replace the cable
harness assembly.
End Connections: The connectors used by Seametrics are not submersible, but are
designed to be splash-resistant.
IMPORTANT NOTE!
When changing batteries, it is important to reset the Battery Life Calculator.
If the battery life calculator is not reset, the remaining life information
will be incorrect. Access the Battery Life Calculator from the Congure Menu
- Battery Information and Reset. If you have put in new batteries, checkmark
the box “I have just put in fresh batteries.” Click Save and Close.
MAINTENANCE

Erratic Readings
Erratic readings can be caused by a poor connection, damaged cable, moisture in the unit,
or a damaged transmitter. In most cases, erratic readings are due to moisture getting
into the system. The rst thing to check is the connection. Look for moisture between
contacts or a loose or broken wire. Next, check the cable for cracking or fraying. If
the connections and cable appear OK, but the readings are still erratic, the transmitter
may be damaged. Contact Seametrics for evaluation and repair. Erratic and erroneous
readings can also occur due to improper grounding. See Grounding Issues, below.
Zero Readings When Pressurized
Continuous zero readings are usually caused by an open circuit which may
indicate a broken cable, a bad connection, or possibly a damaged transmitter.
Check the connector to see if a wire has become loose or if the cable has been cut.
If damage is not readily apparent, contact Seametrics for evaluation and repair.
Grounding Issues
It is commonly known that when using electronic equipment, both personnel and
equipment need to be protected from high power spikes that may be caused by lightning,
power line surges, or faulty equipment. Without a proper grounding system, a power
spike will nd the path of least resistance to earth ground – whether that path is through
sensitive electronic equipment or the person operating the equipment. In order to ensure
safety and prevent equipment damage, a grounding system must be used to provide a
low resistance path to ground.
When using several pieces of interconnected equipment, each of which may have its own
ground, problems with noise, signal interference, and erroneous readings may be noted.
This is caused by a condition known as a Ground Loop. Because of natural resistance in
the earth between the grounding points, current can ow between the points, creating an
unexpected voltage dierence and resulting erroneous readings.
The single most important step in minimizing a ground loop is to tie all equipment
(sensors, dataloggers, external power sources, and any other associated equipment) to
a single common grounding point. Seametrics recommends connecting the shield to
ground at the connector end.
