Leveloader Gold
The sealed design of these
Leveloggers offers protection against
power surges such as nearby pumps or lightning, and greatly simplifies
maintenance.
The Model
3001 Levelogger
Gold (shown) comes in a variety of ranges suitable to measure
compensated water levels and open bodies of water. Levelogger has a datalogger, 10-year battery,
pressure transducer and temperature sensor, all housed in a very
small, minimal maintenance, 7/8" x 4.9" (22 x 125 mm) stainless steel
housing. The 10 year battery life, high accuracy and
long-term stability make this the ideal device for recording water
levels in monitoring and production wells, boreholes, lakes, rivers,
tanks, harbors, etc.
The Model 3001 LTC
Levelogger combines a 4 electrode platinum conductivity sensor with
a pressure transducer, thermistor, 8 year battery and a datalogger all
within a factory sealed maintenance free 0.87" x 10.2" stainless
steel housing.
The software displays temperature
compensated conductivity and water level readings, and temperature. Memory
capacity is 16,000 sets of readings, with options for linear or
event-based sampling, in any interval between 1 second and 99 hours. It
has an accuracy of +/- 0.1 mg/L.
The Barologger
is similar to the LT in a low pressure range ideal measuring atmospheric pressure, to give the most accurate compensation available.
The new
Leveloader Gold is a significantly
improved, backward compatible data transfer unit designed for use with all
versions of the Solinst Levelogger® and Barologger. It is used to download
and store multiple Levelogger data files, using 8Mb of non-volatile FLASH
memory.

Features
Leveloggers can be inexpensively suspended
on a simple wireline, or connected to the surface with direct read cable
for rapid downloading of data and/or reprogramming, without removal from
the water. Using a wireline reduces costs and allows the Leveloggers to be
totally hidden from view and locked away from possible damage.
An inexpensive barologger is available to
provide the most accurate and easy method of barometric compensation/ The
Leveloggers themselves are available in a variety of ranges, as well as in
a version that also measures dissolved oxygen and another that also
measures conductivity.
The fully automatic, easily programmed
Levelogger allows measurements at selected time intervals as small as 0.5
sec. with no wraparound, so that it does not overwrite data. Logarithmic and event-based sampling regimes are also easily programmed in the
easy-to-use software.

Model
3001 Operating Principles
Programming of the
Leveloggers requires one optical reader. Place the first Levelogger
into a reader attached to a desktop or portable computer. Then fill
out the various fields in the program screen with site information and
choice of sampling regime.
The Leveloggers can then
be started immediately, or with a future start time. They can be
pre-programmed and taken to the site at a later time. If immediate
start is chosen the operator can see the loggers working before
deploying them.
A manual measurement of
the initial depth to water is taken in each well and noted as a base
line measurement. When a Barologger is used for barometric pressure
measurements, it is set above high water level in one location on
site.
If direct read cables are
being used, data can be viewed and retrieved from the Levelogger at
any time. Use the handy Leveloader or a portable computer.
To download data from a
Levelogger suspended on wireline, simply remove it from the well and
place it in an optical reader attached to a Leveloader in the field,
or to a computer in the field or back in the office.
Data that has been collected
is retained in the Levelogger until the Levelogger has been restarted.

Software
Leveloggers are programmed
using a desktop or portable computer and an optical reader. The Windows
software is very easy to use. Setup and programming are fast and simple.
The measurement time interval
can be set between 0.5 seconds and 99 hours in linear sampling mode, set to a
choice of short, medium or long logarithmic options or to event-based
options. There is ample space for entering site, customer and sampling
information.
Leveloggers may be
synchronized to the computer clock, and there are options for immediate
start or a future start time. The battery has an estimated life of ten
years and the percentage life remaining is indicated on the programming
screen.
The data downloaded from a
Levelogger has already been automatically temperature-compensated. If the
altitude of the logger has been entered into the altitude field, it will
also have been adjusted for altitude. When a Barologger and the Windows
software is used, barometric compensation is highly accurate and problem
free. The Barometric Compensation Wizard can be used prior to export of
the data to other programs.
The software allows immediate
viewing of the data in graph or chart form, or simple downloading for
future examination. It also allows easy export into a spreadsheet or
database for further processing.
The software can be used with
any type of Levelogger including previous versions.

Options
Direct Read Cables
When it is desired to get
real-time data and communicate with Leveloggers without removal from the
water, they can be deployed using direct read cables.
The lower end of the direct
read cable has a miniaturized infra-red optical reader. The top cap of the
Levelogger is removed and the direct read cable is attached in its place.
In turn the upper ends of the cable attaches, via a PC Interface Cable to
the portable computer.
This allows viewing of the
data, downloading and/or programming in the field.
The full benefits of a sealed
Levelogger with no vent tube or electrical cable connection are also
maintained. The logger is still sealed from all electrical interference
through a Faraday cage effect and cable handling problems are minimized.
Direct Read Cables are
available in standard lengths of:
50', 100', 200', 300', 500',
and 15m, 30m, 60m, 80m, and 100m.
Custom cable lengths up to
1640' (500m) are also available, to fit particular monitoring situations,
as required. Cable markings, each 5' or one meter, may be requested, for
situations where the direct read Leveloggers need to be used in a variety
of locations.
The 1/10" diameter (2.54
mm) cable has an HPDE outer jacket for strength and durability. The
stranded stainless steel central conductor gives non-stretch accuracy.
The upper end of the direct
read cable is fitted with a connector that can act as a well cap for a
1" well. This connector fits into Solinst Levelogger well caps
designed for 2" or 4" wells, and can easily be attached at
surface in other situations.
Wireline Suspension
Leveloggers may also be
suspended in the water on wireline. This is an inexpensive method of
deployment, and if in a well, allows them to be locked out of sight and
inaccessible to anyone with a special key.
Solinst has adapted the Enviro
Cap™ by putting a vent hole in the cap to allow for the equalization of
barometric pressure. The well cap has a convenient eyelet from which to
suspend the Levelogger. It slips over the casing and is locked in place
with a special key.
The Enviro Caps are available
sized for 2" and 4" wells, and well caps for other sizes of well
can also be used.

BaroLogger
Leveloggers measure absolute pressure
(water pressure + atmospheric pressure) expressed in feet or centimeters
of water volume.
The most accurate method of obtaining
changes in water level is to compensate for atmospheric pressure using a
Barologger. This avoids an time lag in the compensation figures and any
errors introduced due to moisture buildup, kinking or damage to vented
cable. It can also be useful to have recorded barometric information to help
determine barometric lag and/or any damping effect from the surface to the
monitored aquifer.
The Barometric Compensation Wizard in the
Levelogger Windows software simplifies the adjustment of the level
measurements for barometric pressure changes, by using the synchronized
data from all Leveloggers on site and the site Barologger.
The overall results give more reliable,
highly accurate level data than that obtained when using high maintenance
and expensive vented cable.

Transferring Data
The Leveloader Gold eliminates the need for a laptop or
PDA as it can perform, in the field, almost all
the functions the user can do with a desktop
computer and the Levelogger Software.
The Leveloader Gold comes
with sturdy cables for USB and RS232 connection
to a PC and with a two-ended ‘Y’ cable for
attachment either directly to a Levelogger, or to the Direct
Read Cable of a Levelogger deployed in the water. On return
to the PC, the Levelogger Gold Software allows downloading
of individual files or all files at the same time.
Field Friendly
Field-located Leveloggers can be reprogrammed on the fly,
or for convenience, with up to 10 personalized
settings files with a ‘future start’ or ‘start
now’ option. These settings files each store a
customized sampling regime, instrument location,
identification, and altitude, which can be pre-programmed in
the Levelogger PC Software at the office and transferred to
the Leveloader Gold for use in the field. The Leveloader can
be synchronized to your PC clock. In turn you can
synchronize Levelogger times to the Leveloader time, to
maintain consistency between field-deployed Leveloggers.
The Leveloader Gold also displays useful information on
battery life, memory levels and firmware versions for both the
Leveloader itself and the attached Levelogger. As with the
Solinst Levelogger Gold, the new Leveloader Gold has
upgradeable firmware, which allows future improvements to
be added to older units. Users can download and install any
future improvement to the onboard software, free of charge.
For security, there is password protection built into the
Leveloader Gold to prevent unauthorized changes to the
Levelogger settings, logging sessions or stored data.
