Important benefits you need to know about
the Heron dipper-log.
The dipper-log is easy to
use.
Just follow the tree easy steps in the
windows and pocket PC based software (Win 95,98,ME,2000 & XP) for
successful installation.
Quick and easy data
download. No calculations needed. The results are shown as compensated
height of water above the logger and depth of water below datum together
with temperature which can be graphed at the click of a mouse.
Barometric Compensation
The dippper-log does not use vented cable.
The dipper-log automatically takes a
barometric pressure reading during the logger installation. This value
is stored in the logger and used to compensate all the water depth and
height results obtained during the mission. The value is also used when
taking real time readings.
Automatic Elevation and Barometric
Compensation
The
dipper-log automatically takes a barometric pressure reading during the
installation procedure. Because the barometric pressure at any point
varies with elevation this reading also compensates for the elevation of
the well. If a bar-log is not used, this one time reading is used by the
logger to compute the depth and height of water based on the barometric
pressure at the time of the launch. This value lso compensates for the
elevation of the site. The forgoing only applies when the dipper-log is
set up at the site of the installation.
Variable Sampling Intervals
A wide
range of sampling intervals is available to the user from one per second
up to one every 255 hours in steps of seconds, minutes or hours. A "log
time" interval is included. This facility increases the reading interval
by one second for each reading allowing a total of 255 measurements over
nine hours, ideal for short term pump tests. The dipper-log can also be
set up to start at a future date and time to take readings at the preset
intervals.
Depth Of Water Range
The
compact design of the dipper-log is ideal for monitoring surface water
and deep water wells. The dipper-log is launched and then installed in
the well with a simple wireline at the required depth. The unit can be
stored inside the well casing giving protection against vandalism.
Well Head Read Out Data Access
For
installations where frequent downloading is required, a well head
readout version is available. This allows full downloading and control
of the dipper-log from the surface without having to constantly remove
the logger from the well. This version also allows real time readings to
be taken, a useful feature for pump and drawdown tests.
