What is the LevelSCOUT?
The Seametrics LevelSCOUTSmart 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 replaceable ½ 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.

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 dened 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 dierence 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.
